Casa Alegria, The Butterfly Dome

Casa Alegria, The Butterfly Dome, is a magical family experience located in San Isidro de El General, south of San José. Rated an impressive 4. 7, this intimate butterfly sanctuary invites visitors to walk through a lush, enclosed dome where hundreds of tropical butterfly species flutter freely, land on willing visitors, and display the stunning natural artwork that makes them one of Costa Rica's most beloved symbols.

For children, the experience of having a live butterfly land on their arm or hand is genuinely unforgettable. Unlike seeing butterflies in a garden or museum display, a walk-through dome puts children in the middle of the action — surrounded, not observing from a distance. The enclosed environment means even young children and toddlers can experience the butterflies safely, and the bright tropical plantings make the dome visually beautiful from start to finish.

To maximize butterfly landings, wear brightly colored or floral-print clothing — the butterflies are naturally attracted to color and will seek out visitors dressed to resemble flowers. Morning visits, when butterflies are warming up in the early sun, are the most active and photogenic time of day. Casa Alegria is a smaller, intimate venue, which means a more personal experience than larger commercial butterfly farms.
