Descend 500 feet into a dormant Galápagos volcano and explore mineral-lit chambers carved by ancient lava. This guided half-day trip from Puerto Villamil combines technical rappelling with sweeping island views and close-up geology.
More ways to explore the area's outdoor wonders
You begin at dawn on a corroded ridge above the Pacific, the wind pushing cool spray toward the cliffs as the trail narrows and the island falls away. The rim of the Triplets gives a last bright panorama—Floreana and Santa Cruz cut like ink on the horizon—before you clip in, lean back, and let rope and gravity bid you down into a cavernous black.

Expect a steep rappel
The itinerary includes a 500-foot descent; disclose any experience limits and follow your guide’s rigging and safety briefings.
Footwear matters
Sturdy, ankle-support hiking boots with good traction help on loose volcanic scree and uneven crater floors.
Bring reliable light
A high-lumen headlamp and spare batteries are essential for exploring dark chambers where phone light won’t suffice.
Hydrate and pace
Carry 1–2 liters of water and sip regularly—heat in the Galápagos can be deceptive when you’re focused on technical moves.
Ankle-support hiking boots
Provide traction and stability on loose volcanic rock and uneven surfaces.
High-lumen headlamp
Illuminates lava tunnels and mineral chambers where natural light is absent.
Gloves with grip
Protect hands during rope work and when handling rough volcanic surfaces.
Sun protection (hat, sunscreen, sunglasses)
Strong equatorial sun and reflective rock increase UV exposure during rim walks.
