Butterfly Conservatory

The Butterfly Conservatory in El Castillo is a breeding and observation site for butterflies with a large open flight area, tropical plants, waterfalls, and streams inside. The facility has several areas where different butterfly species fly freely and can be observed closely by visitors.

The facility started in 2002 when an American transformed a former ranch property into a rainforest project. This founding was part of a larger effort to restore forest cover near Arenal Volcano.

The place teaches visitors about butterflies' importance in nature and shows how these insects connect with other forest life. You can learn how butterflies and native plants depend on each other and what role they play in the ecosystem.

Visitors should expect wet weather and wear light, breathable clothing since it is warm and humid inside. The best time to visit is in the morning when butterflies are more active and easier to observe.

Visitors can see different butterfly species, including rare blue Morpho varieties that are normally hard to spot. These large, brightly colored butterflies are especially striking to watch due to their intense hues.
