Our early morning nature walk with William was nothing short of amazing. He pointed out 37 different birds to us, not to mention snakes, insects, plants and reptiles. A wonderful and memorable three hours.

Had a great experience of Costa Rican rain forest ecology. Tirimbina has excellent guide/educators who helped us see and appreciate the animals, birds, insects and plants. Lodging and food were very good. Staff were friendly, professional, and very helpful toward non-Spanish speakers.
