Welcome to San Luis & Tronadora
San Luis and Tronadora are the tiny twin communities on the southern side of Laguna de Arenal. They are the last outposts of civilization before the landscape gets swallowed by eternal rainforest (the Children’s Eternal Rainforest, to be exact) further south and east. (The 'old' Tronadora did in fact get swallowed up by Arenal's waters when the dam was built.) A small contingent of travelers trickles through here – mostly windsurfers and wanderers – but this wild and windy corner of the lake feels blissfully undiscovered.
