This museum's astounding treasure trove of more than 1,200 masks and 4,700 puppets from across the Indonesian archipelago and beyond is Bali's largest collection, beautifully showcasing two of the island's most prominent forms of cultural expression. This unique collection was donated by a philanthropic Javanese businessman, a devoted collector and visionary, who aimed to preserve this diminishing art form. Exhibits are showcased in a nonchalant, yet charming, manner in several antique teak Javanese joglo houses, reconstructed on-site in lovingly tended gardens. Entrance is, amazingly, free (although donations are appreciated in the box). Few tourists are even aware that this cultural attraction exists, so you'll enjoy the visual feast relatively undisturbed. (The museum is hard to find, south of central Ubud amongst villages famed for their woodcarvers, mask-makers, and sculptors, but it's well worth your efforts.)

Stunning masks and puppet exhibits of all shapes (some life-sized) are thoughtfully themed throughout the joglos and tastefully displayed to allow for up-close inspection. Notables include exquisite carved wooden wayungs (puppets), traditional rod puppets, and leather shadow puppets—the latter being Indonesia's most iconic art form. Spectacular masks originate from across the archipelago, from Bali to Papua, and also extend to representatives of Africa and other global cultures. The puppets come from China, Myanmar, and Cambodia, along with 18th-century Japanese bunraku idols. Masks and costumes may look familiar from Balinese dance performances and most children will find this fascinating stuff. Allow plenty of time for viewing, and for the bucolic splendor of the rice field surrounds—bring a picnic to enjoy in the gardens.
