Step off the tiny plane at Baltra and the air changes: saline, bright, and immediate. On day one the group moves through Puerto Ayora toward the Highlands of Santa Cruz where giant tortoises move with a careful, prehistoric patience and lava tubes cut shadows across the trail. Later the team crosses by public speedboat to Isabela, a broader, younger island where volcanic fingers have created Los Tuneles — a maze of arches, lagoons and underwater caverns.

Wildlife
History
The Galápagos shaped Charles Darwin’s ideas on evolution; islands formed by hotspot volcanism and continuing eruptions create rapidly changing habitats.
Conservation
Galápagos National Park strictly controls visitor movement and biosecurity; travelers should pack out waste, avoid single-use plastics, and use reef-friendly products to minimize impact.
Reserve your spot on the 5-Day Guided Galapagos & Los Tuneles Tour today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Bring reef-safe sunscreen
The Galápagos forbids certain chemicals; choose biodegradable sunscreen to protect coral and marine life.
Prepare for boat crossings
Public speedboats between islands can be choppy — take seasickness medicine and secure electronics in waterproof bags.
Layer for microclimates
Highlands can be cool and humid while coastal sites are hot and sunny; pack a lightweight wind/rain layer.
Follow park biosecurity
Disinfect boots and avoid touching wildlife—the islands enforce strict rules to protect endemic species.
Reef-safe sunscreen
Protects delicate marine ecosystems and complies with park guidelines.
summer
Dry bag (10–20L)
Keeps camera, documents and layers dry during speedboat crossings and snorkeling transitions.
Lightweight hiking boots or trail shoes
Provide traction on varied volcanic terrain for the Sierra Negra trek.
Full or partial snorkel kit (mask/snorkel/fins)
Personal gear often fits better than rental equipment and increases comfort in the water.
