I visited the Monteverde Butterfly Gardens on a recent trip to Costa Rica, and was thoroughly impressed! Their guides (all international volunteers) are incredible - their passion for teaching about nature made the experience such a joy. The place was well-kept and we saw some gorgeous butterflies. The insectarium was excellent, and we learned tons about tarantulas, scorpions, cockroaches, giant beetles and various other Costa Rican insects.
The butterfly gardens are a little off the beaten path, but that makes them all the more appealing. The netted gardens are right in the forest and the view from the reception area is spectacular. This is smaller operation than some that I have seen, but the atmosphere is so personable and friendly it is second to none. A definite must for those traveling through Monteverde!
