Mosquera Islet is a shallow boat dive between Baltra and North Seymour where sandy bottom, low rock, and scattered reef structure attract sea lions, rays, garden eels, and cruising sharks in relatively easy water. It is usually run as a relaxed day-boat site with broad appeal, though tidal flow can still add movement and wildlife action around the channel edges.
Site Conditions
Safety Notes
Entries are usually straightforward, but surface chop and tidal flow in the channel can still separate divers who are slow on descent or ascent. Stay close to the guide and use clear surface signaling from the boat.
Access Restrictions
Boat-only access on day trips or liveaboard itineraries; there is no independent shore entry.
Legal Notes
Mosquera Islet sits inside the Galapagos Marine Reserve, so access is through permitted boat operations and protected-area rules apply.
Community notes to help plan your visit.
Scuba Diving
Max depth around 18 m with mild currents and good visibility; described as suitable for all divers.
Freediving
Mosquera can work for supervised freedive-style drops from a boat in calm conditions, but it is generally run as a scuba site and channel traffic or current can complicate long surface drifts.
Snorkeling
Snorkeling around Mosquera is possible from organized boat trips when conditions are calm enough, especially for sea lion encounters in shallow water near the sand flats.
