This butterfly garden is smaller and less elaborate than the Butterfly Farm, but it provides a good introduction to the life cycle of butterflies. It's also a calm and quiet oasis in a noisy and crowded city, quite close to downtown. Plan on a half-hour to several hours here, depending on whether they have lunch or refreshments at the small coffee shop and gallery. You'll be given a self-guided-tour booklet when you arrive, and an 18-minute video runs continuously throughout the day. Spirogyra is near El Pueblo, a short taxi ride from San José's center.
