A small, locally owned company running the three things people come to La Paz for: snorkelling with the sea lion colony at Los Islotes, the whale sharks in the bay in season, and the day out to Espíritu Santo, the island across the bay that is a UNESCO biosphere reserve and about as good as a desert island gets.
Guides work in English and Spanish, and paddleboarding gets added to trips for people who want it. No street address is published, so this sits on the town centre.
