Kula
An 8-acre upcountry garden of native and exotic plants (proteas, orchids, a small petting area) on the slopes of Haleakalā; a relaxed, low-key stop to pair with a Haleakalā sunrise/summit trip or the 'Ulupalakua wine/vodka run through Kula. Not a headline attraction, more a pleasant half-hour to hour detour.
No advance booking required, self-guided walk. Open daily 9:00am-4:00pm, last admission 3:15pm. $15 adult, $5 child (6-12). Free on-site parking. Address: 638 Kekaulike Ave, Kula, HI 96790.
