What it is

Nani Mau Gardens and Event Space is a 22-acre tropical botanical garden located approximately three miles south of Hilo on the Big Island of Hawaiʻi. The name "Nani Mau" translates to "forever beautiful" in Hawaiian. Established in 1972 from a former papaya patch by Makato Nitahara, the gardens showcase over 2,000 varieties of plants, including more than 225 types of flowering plants, 100 species of fruit trees, and over 2,300 orchids.

The meticulously landscaped grounds feature various themed sections such as an orchid walkway, a ginger garden, a hibiscus garden, rare palms, a fruit orchard, a botanical museum, and Japanese gardens, including a bell tower built without nails. Beyond its role as a botanical attraction, Nani Mau Gardens also serves as a prominent event space, hosting weddings, family celebrations, community events, and other gatherings, with various indoor and outdoor facilities available for rent.

Visitor experience

Visitors to Nani Mau Gardens can expect a peaceful and serene experience, strolling along paved, shaded pathways that wind through lush tropical flora. The gardens are designed for leisurely exploration, offering numerous rest stops and excellent views of the diverse plant collections. Highlights include the extensive orchid displays, anthurium groves, and various waterfalls. The botanical museum provides educational exhibits on the island's tropical plants, their conservation, and their significance in Hawaiian culture.

A gift shop is available on-site for souvenirs. While the gardens have historically featured a restaurant with an "Island Buffet," more recent information suggests dining options like a "Shabu Shabu experience" may require advanced reservations, and the primary focus for food service appears to be tied to events. For general visitors, it's advisable to verify current dining availability.

Safety and cautions

The humid, tropical climate in Hilo, where the gardens are located, can experience significant rainfall, ranging from 127 to 300 inches annually. Visitors should be prepared for wet conditions and potential humidity. Pathways are generally paved and accessible. There are no specific safety warnings or seasonal closures mentioned beyond general considerations for outdoor environments in a tropical climate. Visitors should remain on marked paths and be mindful of natural surroundings.

Editorial take

Nani Mau Gardens is a worthwhile destination for visitors who appreciate botanical beauty, tropical flora, and a serene atmosphere. It's particularly appealing to those looking for a leisurely, peaceful stroll amidst vibrant plant life, including a remarkable orchid collection and various themed gardens. It caters well to families, couples, and individuals seeking a calming experience away from more strenuous activities.

Travelers who might prioritize it are those staying in the Hilo area looking for a self-guided nature immersion. Those who should skip it include travelers primarily seeking active adventure, extensive hiking trails, or a deep focus exclusively on native Hawaiian plant conservation (though it does feature some).

It's important not to confuse Nani Mau Gardens with other botanical gardens on the Big Island, such as the Hawaii Tropical Bioreserve & Garden (formerly Hawaii Tropical Botanical Garden) near Hilo, which offers a different experience, or Pua Mau Botanical Garden in North Kohala, which focuses on arid environments. While Nani Mau Gardens functions as a botanical garden, its significant role as an event space means that certain areas or services might occasionally be dedicated to private functions.
