A full-day crossing from Santa Cruz delivers Bartolomé’s iconic Pinnacle Rock hike and clear-water snorkeling at Sullivan Bay. Expect a two-hour boat ride, a steep 400-step ascent to volcanic summits, and guided swims with penguins and turtles.

The boat cuts through glassy early-morning water out of Itabaca Canal, and for two hours the archipelago unwraps itself: distant islets sharpen, frigatebirds wheel, and then Pinnacle Rock appears like a stone dagger rising from turquoise sea. You step ashore on Bartolomé, where a narrow wooden boardwalk climbs nearly 400 steps to the rim of an extinct volcanic cone — the summit sits roughly 110–120 m above sea level — and opens onto a raw panorama of lava fields, neighboring islands, and miles of reef.
Difficulty
moderate
Duration
8 hours
Fitness Level
Moderately fit: able to climb many stairs and swim/snorkel for short sessions; comfortable with prolonged boat time.
Wildlife
History
These islands are geologically young—volcanic activity created the dramatic lava fields and tuff formations that define Bartolomé and Sullivan Bay, and Park protections date to the mid-20th century.
Conservation
All landings follow Galápagos National Park rules: stay on marked trails, keep distance from wildlife, and use reef-safe products to reduce impact.

Prepare for the boat crossing
Bring motion-sickness meds and a windproof layer — crossing from Itabaca Canal can be choppy and lasts about two hours each way.
Footwear for the stairs
Wear sturdy closed-toe shoes with good grip — the wooden boardwalk has nearly 400 steps and can be hot and dusty.
Use reef-safe sunscreen
Apply reef-safe, biodegradable sunscreen before boarding to protect marine ecosystems and avoid contact with wildlife.
Pack a small dry bag
Keep phone, extra lens, and snacks protected — water taxis and deck space can be wet and windy.
Sturdy trail shoes
Useful for the steep wooden steps and uneven lava rock approaches on Bartolomé.
Reef-safe sunscreen
Protects your skin and the delicate marine environment during snorkeling and beach time.
Light waterproof jacket
Windproof layer for chilly open-ocean crossings, especially early morning.
Quick-dry swimwear & towel
Comfortable underlayers and a towel for snorkeling and post-swim changes.
