Last updated: April 23, 2026

What it is

Botanical World Adventures, located on the Hamakua Coast of the Big Island near Hilo, is a multi-faceted visitor attraction combining extensive botanical gardens with adventure activities. It encompasses the Botanical World Gardens, a large hedge maze, and several waterfalls, notably Kamae'e Falls and Hanapueo Falls. The adventure offerings include zipline tours (Zip Isle), Segway® Off-Road Adventure Tours, and a "Dip in the Waterfall" walk. The botanical gardens feature a diverse collection of tropical plants, including hundreds of wild orchids, an arboretum, and a rainforest trail that leads to waterfalls and streams.

Visitor experience

Visitors to Botanical World Adventures can choose between exploring the gardens at their own pace with a self-guided tour or participating in more active adventures. The botanical gardens offer paved and unpaved trails through rainforests, lawns, and themed areas like the Rainbow Walk and an Orchid Wall. The World-Class Maze is noted as the world's second-largest permanently planted maze, offering a fun challenge for all ages.

For those seeking more adrenaline, the zipline tour features eight lines, including dual racing lines, and a suspension bridge, allowing participants to soar over rainforest canopies, rivers, and waterfalls. The zipline course is designed to accommodate beginners and even children as young as four (in tandem with a guide). Segway tours provide another way to explore the gardens and rainforest trails. A unique "Waterfall Dip Walk and Refresher" tour offers an easy hike to the base of the upper Hanapueo waterfall for a refreshing dip, accessible only through this guided tour.

The gardens provide panoramic views of Mauna Kea, the Pacific Ocean, and Kamae'e Falls. Educational opportunities are available, particularly for children, focusing on plant and wildlife diversity and scientific processes in nature.

Safety and cautions

  • Weather: Tours operate in light rain, which is common on the Hamakua Coast. However, tours may be canceled due to heavy rains, lightning, or strong winds for safety reasons.
  • Physical Exertion: While some garden paths are paved and partially wheelchair accessible, other trails, especially the Rainforest Trail extension and the "Waterfall Dip Walk," involve moderate exertion and may include steep staircases.
  • Zipline Restrictions: Ziplining has age and weight requirements; solo zipping generally requires ages 13 and up and a weight between 70 to 275 lbs. Children as young as 4 can participate in tandem with a certified guide (minimum 35 lbs). Closed-toe shoes are required for ziplining, and long pants are recommended.
  • Valuables: Visitors are advised to leave valuables in secured areas before ziplining, as items can fall from pockets and may not be retrievable from the rainforest.
  • Accessibility: The gardens are partially wheelchair accessible, with paved paths to Kamae'e Falls overlook, the Rainbow Walk, and parts of the Rainforest Trail. However, some areas may not be suitable for all guests. Segway tours are presented as an accessible option for those who prefer not to hike long distances.

Editorial take

Botanical World Adventures is an excellent choice for families and groups with varied interests, especially those staying on the Hilo side of the Big Island. It caters to both nature enthusiasts seeking a tranquil garden experience and thrill-seekers looking for an adventure. Travelers who appreciate lush tropical flora, waterfalls, and panoramic views will enjoy the botanical garden. The zipline and Segway tours add an element of excitement for those wanting a more active experience. Its family-friendly zipline options make it suitable for visitors with younger children (ages 4 and up for tandem ziplining).

Those who should prioritize it are families, multi-generational groups, and individuals interested in combining botanical beauty with soft adventure activities in one location. It's a particularly good option for a half-day or full-day outing, especially if combining multiple activities.

Travelers seeking only strenuous, off-the-beaten-path hikes or those solely interested in specific extreme sports might find the adventure offerings more structured than they prefer. However, the gardens themselves offer a degree of self-guided exploration.

This location should not be confused with other botanical gardens on the Big Island, such as the Hawaii Tropical Bioreserve & Garden (formerly Hawaii Tropical Botanical Garden), which is purely a botanical garden experience, or other zipline operators like Umauma Falls Experience or Kohala Zipline, which are distinct entities despite offering similar adventure activities on the Big Island. Botanical World Adventures uniquely combines these elements into a single destination.
