From specialized birds soaring above steaming craters to resilient mammals that have evolved to thrive in these harsh conditions, the biodiversity surrounding active and dormant volcanoes presents a fascinating glimpse into nature’s adaptability. This article explores some of the world’s most remarkable volcano trails where visitors might be fortunate enough to spot rare and unique wildlife, combining the thrill of volcanic landscapes with unforgettable wildlife observation experiences.
Mount Kilimanjaro, Tanzania: Home to Endangered Primates
Africa’s highest peak offers more than just a challenging climb—it’s a biodiversity hotspot featuring distinct ecological zones. As hikers ascend Mount Kilimanjaro’s slopes via the Machame or Lemosho routes, they traverse through lush rainforest zones where the endangered Abbot’s duiker, a rare forest antelope found almost exclusively on this mountain, might be glimpsed in the early morning hours. The secretive black-and-white colobus monkeys, with their distinctive long white tails, often gather in the canopy, while the vulnerable Abbott’s starling—a bird species found only in a few mountainous regions of Tanzania and Kenya—can occasionally be spotted in the montane forests.
What makes Kilimanjaro particularly special is its isolated ecosystem, essentially creating an island of biodiversity surrounded by plains. This isolation has led to the evolution of endemic species and subspecies. The Kilimanjaro shrew and the chameleons of the upper forest zone have adapted specifically to this volcanic environment. For wildlife enthusiasts, the Shira Plateau offers the best viewing opportunities, especially during the dry seasons (January-March and June-October) when animals congregate near water sources. Rangers recommend hiking with local guides who know precisely where these elusive creatures tend to appear.
Volcanoes National Park, Rwanda: Sanctuary of the Mountain Gorillas
Few wildlife encounters rival the emotional experience of observing mountain gorillas in their natural habitat, and Rwanda’s Volcanoes National Park offers one of the most accessible opportunities to witness these critically endangered primates. The park encompasses five volcanoes from the Virunga Mountains, creating a dramatic backdrop for gorilla trekking expeditions. Beyond the famous gorillas, the volcanic slopes harbor golden monkeys, another endangered primate species with striking orange-gold coloration that’s endemic to the Albertine Rift. These playful creatures are often spotted in bamboo forests, providing a delightful secondary wildlife objective for trekkers.
The volcanic soil of this region supports dense vegetation that provides ideal habitat for over 200 bird species, including the rare Rwenzori turaco with its crimson wings and distinctive crest. Hiking the Bisoke Volcano trail, visitors might encounter forest elephants, buffalo, and giant forest hogs in the lower elevations. Conservation efforts in Volcanoes National Park have created one of Africa’s greatest wildlife success stories, with mountain gorilla populations slowly increasing after decades of decline. Guided treks to see these magnificent creatures require permits that should be secured months in advance, particularly during the dry seasons (December-February and June-September).
Arenal Volcano National Park, Costa Rica: Biodiversity in Volcanic Rainforests
Costa Rica’s most active volcano until 2010, Arenal now offers relatively safe hiking opportunities through former lava fields and rainforests teeming with wildlife. The Arenal 1968 Trail and the Los Tucanes Trail wind through secondary forests and old lava flows, providing unique habitats where specialized species have colonized the volcanic terrain. Lucky hikers might spot the resplendent quetzal, considered one of the world’s most beautiful birds with its iridescent green plumage and long tail feathers. The endangered great green macaw also makes its home in this region, with several pairs nesting within the park boundaries.
What makes Arenal particularly fascinating for wildlife enthusiasts is the visible ecological succession—observing how plant and animal communities gradually reclaim areas previously devastated by eruptions. The volcano’s slopes harbor three-toed sloths, howler monkeys, and white-faced capuchins, while the elusive jaguarundi and margay (small wild cats) occasionally cross the trails in early mornings. Approximately 850 bird species have been documented in the greater Arenal region, including the fascinating bare-necked umbrellabird with its distinctive umbrella-like crest. For the best wildlife viewing opportunities, guides recommend hiking during the transitional hours of dawn and dusk, and visiting during the dry season (February to April) when animals frequently visit water sources near the trails.
Tongariro Alpine Crossing, New Zealand: Endemic Birds in Volcanic Landscapes
New Zealand’s most famous day hike traverses a dramatic volcanic landscape featured prominently in “The Lord of the Rings” films. The 19.4-kilometer Tongariro Alpine Crossing takes hikers past active craters, emerald lakes, and ancient lava flows—environments that support unique wildlife adapted to alpine volcanic conditions. The endangered North Island brown kiwi maintains a small population in the shrublands surrounding the volcanic massif, though these nocturnal birds are rarely spotted by day hikers. More commonly observed are the New Zealand falcon (kārearea) and the endemic New Zealand pipit (pīhoihoi), both of which have adapted to the harsh alpine environment.
What makes Tongariro particularly special is how wildlife has adapted to the geothermal features. Several insect species, including unique alpine wētā (large flightless insects endemic to New Zealand), have evolved to use the warm volcanic soils to survive the harsh alpine winters. The colorful alpine grasshopper—found only in New Zealand’s volcanic regions—has developed specialized physiological adaptations to thrive in this extreme environment. Conservation efforts focus on predator control to protect ground-nesting birds like the rare blue duck (whio), which can occasionally be spotted in streams near the beginning and end of the crossing. For wildlife enthusiasts, hiking outside peak summer months offers better opportunities for bird sightings, though winter conditions require advanced alpine skills and proper equipment.
Mount Etna, Sicily: Mediterranean Wildlife on Europe’s Most Active Volcano
Europe’s tallest active volcano offers surprisingly rich wildlife viewing opportunities across its diverse elevation zones. The Piano Provenzana trail on Mount Etna’s northern slope and the southern Rifugio Sapienza route allow hikers to explore multiple ecosystems as they ascend toward the summit craters. The Etna birch (Betula aetnensis), a species unique to this volcano, creates distinctive woodlands that support endemic subspecies of birds including the Etna long-tailed tit and the local race of rock partridge. One of the most charismatic mammals found on Etna’s slopes is the Etna wild rabbit, a subspecies that has evolved distinctive characteristics from mainland populations.
What makes Etna’s wildlife particularly fascinating is how animals have adapted to periodic eruptions and landscape changes. Several reptile species, including the Sicilian wall lizard, have developed populations on the volcano with unique coloration patterns that provide camouflage against the dark volcanic rocks. Bird watchers might be rewarded with sightings of the elusive rock thrush and the Egyptian vulture, which maintains one of its last Italian breeding populations on Etna’s remote slopes. Spring (April-June) offers the best wildlife viewing opportunities when migratory birds return and wildflowers attract numerous butterfly species, including the endemic Etna brimstone butterfly. Local guides emphasize that morning hikes starting at dawn provide the best chances to spot wildlife before the arrival of larger tourist groups.
Hawaiʻi Volcanoes National Park: Evolution in Isolation
Home to two of the world’s most active volcanoes—Kīlauea and Mauna Loa—this remarkable national park showcases how wildlife evolves in extreme isolation. The Kīlauea Iki Trail and the Crater Rim Trail offer accessible routes where visitors might encounter some of Hawaii’s unique endemic species. The ‘amakihi, a native honeycreeper, has remarkably adapted to living in volcanic landscapes and can be spotted feeding on the nectar of ʻōhiʻa lehua flowers that colonize recent lava flows. The Hawaiian hawk (ʻio), an endangered raptor found nowhere else on Earth, soars above the volcanic landscape hunting for prey among the recovering forests.
The park’s isolation has led to remarkable evolutionary adaptations. The happyface spider, named for the distinctive marking on its abdomen, has evolved various color morphs specific to different habitats within the volcanic environment. Night hikes with certified guides offer opportunities to spot the endangered Hawaiian hoary bat (ōpeʻapeʻa), Hawaii’s only native land mammal. Perhaps most remarkable are the lava tube ecosystems, where specialized cave-adapted creatures—some found nowhere else on the planet—have evolved in complete darkness. For optimal wildlife viewing, rangers recommend visiting during the cooler months (October to April) and exploring different elevation zones throughout the park, from coastal areas to upper mountain slopes where distinct wildlife communities have developed.
Galápagos Islands, Ecuador: Volcanic Evolution Laboratory
The Galápagos Islands represent one of Earth’s most remarkable wildlife destinations, where volcanic activity has created the foundation for evolutionary processes that inspired Darwin’s theory of natural selection. Hiking trails on Isabela Island—particularly those around Sierra Negra and Volcán Chico—take visitors across recent lava flows and into habitats where endemic species have evolved in isolation. The iconic Galápagos giant tortoise can be observed grazing on vegetation that has colonized volcanic slopes, while the marine iguana—the world’s only sea-going lizard—basks on coastal lava rocks after feeding on underwater algae.
What makes the Galápagos volcanic trails particularly special is witnessing how different species have adapted to distinct volcanic environments across the archipelago. The Galápagos hawk, the islands’ top predator, nests on volcanic cliffs and hunts across the lava fields. Various Darwin’s finch species demonstrate specialized beak adaptations for exploiting different food resources available in these volcanic habitats. For visitors seeking rare wildlife, the mangrove finch—critically endangered with fewer than 100 individuals remaining—can sometimes be spotted in specific locations on Isabela Island. The National Park Service strictly regulates hiking to protect fragile ecosystems, requiring visitors to be accompanied by certified naturalist guides who know precisely where and when to look for specific species, particularly during the cool, dry season (June to November) when many animals are most active.
Mount Fuji, Japan: Alpine Wildlife on an Iconic Volcano
Japan’s most recognizable natural landmark harbors surprising biodiversity across its different elevation zones. The Yoshida Trail, the most popular route to Mount Fuji’s summit, passes through four distinct ecological zones where specialized wildlife has adapted to the volcanic environment. The Japanese serow, a goat-antelope designated as a Special Natural Monument in Japan, occasionally appears on the mountain’s middle slopes. Bird enthusiasts might spot the Japanese accentor, an alpine species that nests among the volcanic rocks above the treeline, while the Asian stubtail warbler can be heard singing in the forests at lower elevations.
What makes Fuji’s wildlife particularly interesting is how some species have developed specialized behaviors to take advantage of the mountain’s microclimates. The Japanese dormouse hibernates in the volcanic soil, utilizing its insulating properties during winter months. Several butterfly species, including the endemic Fuji copper butterfly, have evolved populations specifically adapted to the mountain’s volcanic habitats and can be seen during summer months pollinating alpine flowers. Though Fuji is extremely popular with hikers, wildlife viewing opportunities are best during weekdays in early summer (June-July) before the main climbing season begins. Local conservation groups offer specialized guided hikes focused on wildlife observation along less-traveled routes on Fuji’s northern and eastern slopes, where human disturbance is minimized.
Timanfaya National Park, Lanzarote: Adaptations to Barren Volcanic Landscapes
The dramatic “Fire Mountains” of Lanzarote showcase one of Earth’s most extreme volcanic landscapes, where eruptions between 1730 and 1736 covered nearly a quarter of the island. The Volcano Route (Ruta de Los Volcanes) allows visitors to explore this otherworldly terrain where life has found remarkable ways to colonize seemingly barren lava fields. The Canarian Egyptian vulture, critically endangered and locally known as “guirre,” soars above the volcanic cones searching for food. This is one of the few large bird species that has adapted to the harsh environment of recent lava flows. The small Canarian shrew, found only in the Canary Islands, has established populations in isolated pockets where vegetation has gained a foothold.
What makes Timanfaya’s wildlife particularly fascinating is observing primary ecological succession—the process by which life gradually colonizes new volcanic terrain. Various endemic invertebrates, including the Canarian black beetle and specialized spider species, have evolved to exploit the volcanic substrate’s unique properties. Lichens represent the first colonizers of new lava flows, with over 180 species documented in the park. These create the foundation for more complex life forms to follow. For visitors interested in wildlife, the guided walking route through Las Montañas del Fuego provides opportunities to observe these adaptation processes, particularly during spring months (February-April) when brief rains trigger blooming of pioneer plant species and increased invertebrate activity. Morning visits offer the best chance to spot the resident bird species before afternoon heat reduces animal activity.
Kamchatka Peninsula, Russia: Brown Bears Among the Volcanoes
Russia’s remote Kamchatka Peninsula contains one of the world’s most active volcanic regions within the UNESCO-listed Kamchatka Volcanoes World Heritage Site. The Avacha Volcano trail and routes through Klyuchevskoy Nature Park offer intrepid hikers opportunities to witness remarkable wildlife thriving among these northern volcanoes. The Kamchatka brown bear, representing one of the largest brown bear populations on Earth, frequents the salmon-rich rivers that flow from volcanic slopes. These magnificent predators can sometimes be observed fishing or foraging for berries in meadows surrounded by smoking volcanic cones. The peninsula’s isolation has preserved ecosystems where large mammals, including wolves, reindeer, and wolverines, maintain healthy populations.
What makes Kamchatka particularly special is how geothermal features influence wildlife behavior and distribution. The peninsula’s famous Valley of Geysers creates microhabitats where specialized plant communities support unique insect populations, which in turn attract birds like the rare Steller’s sea eagle—one of the world’s largest eagle species. The Siberian grouse and black-billed capercaillie inhabit forests on the lower volcanic slopes, while the majestic Steller’s sea lion can be spotted along coastal areas where lava flows meet the sea. Wildlife viewing in Kamchatka requires careful planning due to the region’s remoteness and short summer season. Most guided wildlife expeditions operate between July and September, when animals are most active and volcanic trails are reasonably accessible without specialized equipment.
Nyiragongo Volcano, Democratic Republic of Congo: Primates of the Virungas
Containing the world’s largest active lava lake, Mount Nyiragongo offers one of Africa’s most challenging but rewarding volcanic hikes. The trail to the summit crater passes through several distinct ecological zones within Virunga National Park, Africa’s oldest national park and a biodiversity hotspot. The lower slopes harbor small populations of eastern lowland gorillas, though these are encountered less frequently than their mountain gorilla cousins in neighboring volcanoes. More commonly spotted are chimpanzees, which maintain healthy populations in the forests surrounding Nyiragongo and neighboring Nyamuragira volcano. L’Hoest’s monkey, an endangered primate species endemic to the Albertine Rift, can sometimes be observed in small family groups along the forested sections of the trail.
What makes Nyiragongo particularly fascinating from a wildlife perspective is how animals have adapted to periodic volcanic activity. Several bird species, including the Rwenzori turaco and strange weaver, have developed specialized feeding behaviors to exploit resources in recently disturbed volcanic habitats. The forest elephant, though rarely seen by hikers, leaves evidence of its presence through footprints and disturbed vegetation.
