An office in the centre of La Paz running the Espíritu Santo archipelago day — snorkelling at La Lobera with the sea lions, then a couple of hours on an empty beach — with boats leaving from Marina Costa Baja.
Food, drinks and a certified guide are included, and they will run the whole thing as a private charter with a flexible itinerary, which on a day when four boats are queueing at Los Islotes is worth something.
