More ways to explore the area's outdoor wonders
You step off the skiff onto a sliver of volcanic sand and the world rearranges its priorities: wind, salt, and a sharp black crust of lava that looks like it pushed up from the planet’s guts yesterday. On Bartolomé Island the trail climbs quickly—stairs cut into cinders and pumice—until the spit of land with Pinnacle Rock drops into view, a jagged lighthouse of hardened lava that dares the sea to move it.
Difficulty

Fitness Level
Should be comfortable with a steep 30–40 minute climb (about 360 steps) and moderate swimming/snorkeling activity.
Wildlife
History
Bartolomé and Sullivan Bay are products of recent volcanic activity in the Galápagos; Pinnacle Rock is an eroded lava cone formed as the island rose from the sea.
Conservation
Tours operate under Galápagos National Park rules—stay on marked paths, avoid touching wildlife, and use reef-safe sunscreen to minimize impact.

Book early morning departures
Boats leave very early to beat afternoon winds; plan for a 5:30–6:30 AM pickup from Puerto Ayora.
Rent a wetsuit if you get cold
Wetsuits aren’t included—water temps can be cool due to upwelling; a 3mm wetsuit makes snorkeling far more comfortable.
Wear sturdy shoes for lava
The summit trail and Sullivan Bay’s lava fields are sharp and uneven—light hiking shoes or sturdy water shoes protect feet and ankles.
Use reef-safe sunscreen
Apply mineral or reef-safe sunblock before boarding to protect coral and marine life; reapply with a towel between water sessions.
Light wetsuit (3mm)
Keeps you warm during the 45-minute snorkeling session when currents and upwelling lower water temperature.
Sturdy water shoes or hiking shoes
Protects feet on sharp volcanic rock and gives traction on loose cinders during the climb.
Reef-safe sunscreen and lip balm
High UV and reflection from water demand reliable protection that won’t harm marine life.
Waterproof camera or dry bag
Protects gear on deck and lets you capture underwater moments during snorkeling.
