I didn’t plan my Big Island trip around botanical gardens, but they quickly became some of my favorite stops. Between all the beach-hopping and volcano hiking, I loved having peaceful places to stroll under a canopy of palms, smell wild ginger, and learn more about Hawaii’s unique ecosystems. If you’re craving green space and quiet moments, here are 9 Big Island botanical gardens I’d absolutely recommend.
1. Hawai’i Tropical Bioreserve & Garden (Hilo)
This lush, 40-acre garden is the crown jewel of Hilo’s rainforest coast. The boardwalk winds through waterfalls, orchids, ferns, and tropical trees, all set along Onomea Bay. I felt like I stepped into a dream—birds chirping, mist rising off the leaves, and barely anyone else around. Give yourself at least an hour here (longer if you’re a plant lover).
2. Liliʻuokalani Gardens (Hilo)
Right in the heart of Hilo, this peaceful park blends Japanese design with ocean views. There are koi ponds, stone bridges, pagodas, and perfect spots to sit and watch the sunrise. It’s not a botanical garden in the traditional sense, but the landscaping is stunning. I walked here every morning during my Hilo stay.
3. Panaʻewa Rainforest Zoo & Gardens (Hilo)
If you’re traveling with kids—or just curious about animals—this free zoo and garden combo is such a fun stop. It’s the only tropical rainforest zoo in the U.S., and the landscaping is filled with native and exotic plants. I was surprised by how much I enjoyed wandering through here, especially the orchid garden and big cats enclosure.
4. Sadie Seymour Botanical Gardens (Kailua-Kona)
Smaller than others on the list, but lovely in its own way. Located on the grounds of a cultural learning center, this garden has a thoughtful layout of native Hawaiian plants organized by region. I found it to be a quiet, educational spot tucked away from the Kona bustle.
5. Amy B.H. Greenwell Ethnobotanical Garden (Captain Cook)
This garden focuses on traditional Hawaiian plants and how they’ve been used throughout history. There’s a strong sense of cultural respect here, and I left with a deeper understanding of native agriculture. It’s not flashy, but it feels meaningful—especially if you’re into local heritage.
6. World Botanical Gardens & Waterfalls (Hakalau)
This privately-owned garden sprawls across 300 acres and includes tropical plants, hiking trails, and a zipline (yes, really). The highlight for me was Umauma Falls, a triple-tier waterfall that’s easily accessible. I wouldn’t call this the most curated garden, but it’s big and fun to explore.
7. Nani Mau Gardens (Hilo)
This place has an old-school charm—orchid greenhouses, bonsai trees, and wide lawns dotted with fruit trees. It’s less visited than some of the bigger gardens, so I almost had the place to myself. If you enjoy peaceful strolls and a slightly faded but nostalgic vibe, you’ll appreciate Nani Mau.
8. Laupāhoehoe Train Museum Gardens
While small, the gardens around this historic museum were a sweet surprise. They’re well-kept and reflect local flora, plus the museum itself is worth a quick visit if you’re driving along the scenic Hamakua Coast. Not a major stop, but a charming one if you’re nearby.
9. Kona Cloud Forest Sanctuary
This one’s by tour only, but if you can snag a reservation—it’s worth it. Set high in the hills above Kona, the cloud forest is completely different from the coastal gardens. I saw towering tree ferns, rare palms, and a misty, almost enchanted atmosphere that felt worlds away from the beach. Bring a light jacket—it’s cool and damp up here.
Final Thoughts
If you’re planning a trip to the Big Island and want to balance out the beaches and volcanoes with some peaceful greenery, these botanical gardens offer the perfect detour. I left each one with a better appreciation of Hawaii’s plant life—and honestly, just feeling calmer. If I had to pick favorites: Hawai’i Tropical Bioreserve for beauty, Amy Greenwell Garden for history, and Liliʻuokalani Gardens for daily vibes.
