What Travellers Say
Reviews Summary
Visitors praise Lyon Arboretum for its wild, natural beauty and immersive rainforest experience, often comparing it favorably to more curated gardens. The opportunity to hike to Manoa Falls and discover diverse plant life is a major draw. However, the abundance of mosquitoes and occasional muddy trails are significant drawbacks for some, impacting the overall enjoyment.
"If Waimea Valley feels like a well-curated garden of Hawaiian endemic plants, this place feels more like nature’s wild side—diverse, lush, and almost primitive. The trails are quieter, more private, and give you the sense that you’re walking closer to nature. Plus, catching glimpses of the mountain range from inside the valley was a nice surprise.
But fair warning: the mosquitoes here are thriving! During our whole stay in Oahu, we barely saw any, but today they threw a party. I gave a donation at the visitor center, while my wife ended up giving a “blood donation” to the mosquitoes. 🦟😂"

"An incredible experience! Stunning scenery complemented by a diverse array of indigenous plants. Truly nature at its finest! The staff were warm and welcoming, making the visit even more enjoyable. Highly recommend to anyone who appreciates the beauty of the natural world—definitely worth your time!"

"Beautiful place with wonderful views, however if you come during raining season prepare to bring ponchos/rainjackets as it can get pretty rainy at times (more than I was expecting). Also put on bug spray (they sell at the gift shop if you don’t have), it is absolutely a necessity as I got bitten pretty badly on my legs. If you are sensitive to bites, I would also recommend long sleeved clothing. Personally will not be returning due to my sensitivity to bites but definitely worth checking out once for some great nature sights."

Navigating the Trails and Nature
The arboretum is home to over 5,000 species of exotic and native Hawaiian plants, creating a vibrant and diverse ecosystem. Visitors can expect to see a wide array of tropical flowers, towering trees, and unique botanical specimens. Keep an eye out for native birds like parrots and cardinals, which add to the natural symphony of the forest.
However, a significant aspect of the onsite experience is the prevalence of mosquitoes. They are particularly active during the rainy season and can be quite bothersome. Visitors are strongly advised to bring potent insect repellent and consider wearing long sleeves and pants to protect themselves.
The Manoa Falls Connection
Many visitors find that exploring Lyon Arboretum first provides a rich introduction to the local flora, enhancing the appreciation for the natural environment encountered on the Manoa Falls trail. The combination offers a comprehensive experience of the lush Manoa Valley, from botanical wonders to a scenic cascade.

The arboretum also delves into Hawaiian ethnobotany, exploring the traditional uses of plants by the indigenous people of Hawaii. This aspect offers a deeper understanding of the cultural significance of the flora and its historical role in medicine, food, and daily life. Special events and workshops, like the wild foraging adventure, highlight this connection.
For those interested in learning about the ecological and cultural heritage of Hawaii, Lyon Arboretum provides an invaluable educational experience. It’s a place where the beauty of nature meets scientific research and cultural preservation.
