Laguna is the largest of the Tortuguero lodges, with a mix of concrete and wood buildings spread out over 12 acres of grounds on a thin sliver of land between the ocean and the first canal inland, and it hums with activity. Jam-packed package tours begin in San José and embark from boats at Caño Blanco, north of Siquirres. Rooms have wood floors and paneling and tiled bathrooms. The property includes a butterfly garden and a small network of trails through secondary forest. Meals are served buffet-style at the open-air restaurant that extends out over the canal. The snazzy combo reception-gift shop-meeting room building seems to have sprung straight from the mind of Gaudí.
