We used Dive Academy Ballena Blanca to book this excursion and had a wonderful guide: Milton. Milton was also our guide for a snorkeling adventure we booked through Dive Academy. The company provided transportation to & from our hotel. We drove to CURU National Park and had a guided walking tour in the jungle. There were other large groups there, but just four plus our guide in ours. It was very cool to have such a knowledgeable native educating & explaining so much to us in intricate details. Milton has a rich family history and personal experience with the wildlife and culture of Costa Rica which made our excursion that much more enjoyable & educational. We were able to see some incredible & rare wildlife including the White-faced monkeys, Howler Monkeys, the "Drunk Butterfly", Jesu-Christo Lizard, Agouti, and Motmot. We also learned about the Saba & Guanacasta trees and wild boar (no boar sightings, but it's scent told us it was nearby!) Fabulous tour thanks to Dive Academy Ballena Blanca S.A.
