Step into the unique landscapes of Isabela Island as you hike across Sierra Negra’s massive caldera and Volcán Chico’s rugged lava fields. Along the way, enjoy highland forests, volcanic terrain, and spectacular viewpoints that showcase the Galápagos’ diverse ecosystems. This full-day hike blends adventure with insights into the island’s natural history and geology.
You’ll start with a transfer from Puerto Villamil to the trailhead at El Cura station. The drive offers a gradual introduction to the island’s changing landscapes, moving from coastal lowlands into cooler highlands. Once at the trailhead, your guide will go over the route, highlight safety considerations, and suggest tips for managing the hike comfortably.
The trail begins through highland forests where dense vegetation, endemic plants, and birdlife create a cool, shaded environment. As you climb, the forest gradually gives way to open, volcanic terrain. Reaching the caldera rim, you’ll be rewarded with sweeping views over the enormous Sierra Negra crater. Pausing here, you can take photos, rest, and hear the guide explain how volcanic activity has shaped this landscape over millennia.
Continuing to Volcán Chico, the scenery changes dramatically. Black and reddish lava fields stretch across the horizon, punctuated by vents, fissures, and fumaroles. Walking on uneven volcanic rock requires careful footing, but the effort is matched by the visual rewards: panoramic views of the Pacific, surrounding islands, and intricate lava formations. Breaks along the route allow you to spot native plants and birds while enjoying the sense of isolation in this otherworldly landscape. A boxed lunch at a scenic point provides time to rest and take in the surroundings before returning along the highland trail to the starting point and transfer back to Puerto Villamil.
Sierra Negra is located on the southern side of Isabela Island and contains one of the largest volcanic calderas in the world, measuring around 9 km across. Its highlands are cooler and wetter than the lowlands, supporting unique flora and endemic bird species. Hiking here offers an intimate view of these contrasting ecosystems.
Volcán Chico lies along the caldera rim and presents a starkly different environment. Recent lava flows, vent formations, and barren lava fields dominate the landscape, providing insight into the island’s volcanic activity. Clear skies allow long-range views across the island and out to the ocean, and the terrain is ideal for observing the interplay between volcanic geology and the sparse but adapted wildlife.
Hikers should be in good physical condition, as the trail is roughly 16 km (10 miles) round trip with moderate inclines, uneven surfaces, and some steep sections. Proper hiking shoes, sun protection, and sufficient water are essential for comfort and safety. Those with mobility or respiratory issues should consult a doctor before attempting the hike.
Previous hiking experience helps, but is not required. The guide sets a steady, comfortable pace and can assist along tricky sections. Be prepared for temperature changes from the shaded highlands to the exposed caldera and lava fields, and bring layered clothing to adapt to varying conditions.
Local guides provide in-depth knowledge of Isabela’s geology, endemic flora, and birdlife, ensuring that every stop is educational as well as enjoyable. Their expertise allows for a safe and engaging hike, tailored to the group’s pace and interests.
Tours prioritise environmental responsibility, supporting conservation initiatives and highlighting the fragile ecosystems of the Galápagos. Small group sizes allow for personal attention, wildlife observation, and plenty of time to absorb the island’s volcanic landscapes.
The hike covers about 16 km round trip, with a mix of forested trails and rugged volcanic terrain. Some areas are steep and uneven, so maintaining balance is important. Breaks are taken regularly to rest and enjoy views.
Even those not accustomed to hiking can complete it with a steady pace and proper preparation. The guide adjusts the pace and provides support to ensure everyone can enjoy the experience safely.
Sturdy hiking shoes with good grip are essential due to uneven volcanic rocks and loose soil. Breathable, layered clothing is recommended for temperature changes, from cooler highlands to exposed caldera areas.
Sun protection, including a hat, sunglasses, and sunscreen, is crucial. A small backpack can carry water, snacks, and personal items. Layers help you adapt to changing weather along the trail.
Yes, anyone aged 14 and above can take part, provided they are comfortable with moderate physical activity. Younger teens may need supervision or encouragement on steeper sections.
The hike can be educational and enjoyable, with opportunities to see wildlife, lava formations, and learn about the island’s geology from the guide.
Highland forests host endemic birds, including finches and mockingbirds, as well as unique plants adapted to volcanic soil. Small reptiles may be spotted among rocks and vegetation.
On the caldera rim and Volcán Chico, wildlife is limited due to harsh conditions, but the geological features themselves tell a story of volcanic activity and ecosystem adaptation.
A boxed lunch is included, typically at a scenic point overlooking the caldera. Water should be carried additionally to stay hydrated during the hike.
Lunch breaks allow time to rest, enjoy the views, and discuss volcanic and ecological features with the guide.
The full hike usually takes 5–7 hours, including stops for photos, rest, and lunch. Group pace and interest in wildlife or photography can affect the total duration.
The guide ensures a manageable pace, balancing exploration with physical comfort so the day remains enjoyable.
Tours may be modified or cancelled for safety in case of severe weather or volcanic hazards. The guide monitors conditions and communicates any changes.
Safety is the top priority, and alternative arrangements or refunds are provided if conditions prevent a safe hike.
