Select participants and date
You step off the ferry into Puerto Ayora before dawn and the air smells of diesel and sea salt. Boats are tied up like sleeping animals while guides load coolers and tanks; by midmorning you’re already inland, the island slipping under a canopy that changes with every kilometer — dry, wind-sculpted lowlands give way to humid highland forest where giant tortoises move through ferns like slow shadows.

Adventure Tips
Use reef‑safe sunscreen
Bring biodegradable, reef‑safe sunscreen for all boat and snorkeling stops to protect fragile marine ecosystems.
Footwear swap
Wear sturdy trail shoes for crater and highland walks and bring water shoes for Las Grietas and beach landings to protect feet on volcanic rock.
Morning for tortoises
Plan the highland portion for the cooler morning hours when tortoises are most active and photo-friendly.
Bring a dry bag
A small dry bag keeps electronics and spare clothes safe on a wet boat deck or accidental splashes during snorkeling segments.
