The Rainbow Eucalyptus walk at Keahua Arboretum near Kapa'a, Hawaii (Kauai) is an easy 0.3-mile out-and-back trail that passes numerous Rainbow Eucalyptus trees (Eucalyptus deglupta) in the park.

This is not a hike, but a nice short walk that leads through the Keahua Arboretum as it passes through a grove of Rainbow Eucalyptus trees along the way. The Rainbow Eucalyptus trees display their green, red, and brown bark in vertical patterns; however, these trees do not have a strong fragrance like most eucalyptus species. The track leads south before heading east towards the Keahua Stream where I found folks swimming in the stream. There's a nice view of the mountains from this part of the park too - which provide views of the colorful painted bridge that spans across the stream.

Eventually, we walked west again and uphill to where onsite facilities (outhouses) can be found, which is where we turned back due to the abundance of mosquitos.

Visitors will find parking along Kuamo'o Road on the northern side of the road, at the coordinates provided. The lot is large enough to fit just over a dozen vehicles.

This park does appear to be a popular weekend spot for locals to gather on weekends, but otherwise does not appear to be a super-popular place for visitors or tourists as of July, 2022. Please respect the locals and if planning to visit the Rainbow Eucalyptus trees, do not stay long so that the locals can have their parking spots too.

The Keahua Arboretum has outhouse facilities located at the top of the hill, near where this recording ends.

Mosquitos: This trail has a lot of mosquitos due to its proximity to the Keahua Stream.

Respecting the Land
Hawaiian land is considered sacred to native Hawaiians and many locals, so please stay on-trail, take nothing but photos, and leave nothing but footprints. Respect the locals - don't stay for long and have a backup hike planned in case the parking lot is full.

Before you leave...

MyHikes is an indie web platform aimed to make exploring public trails easier for everyone. The site has no investors and is owned and operated by one person, Dave Miller / Admin. As the main contributor and doer-of-all-things for MyHikes, I share my experiences from hikes and backpacking trips on MyHikes for fun on a volunteer basis and I believe that public trail information should be available to everyone.

It takes a lot of time 🕦, money 💰, and effort (including espresso shots ☕) to run MyHikes, including hiking , mapping , writing , and publishing new trails with high-quality content... along with building new features, moderating, and site maintainance . I simply ask that if you find our content helpful or useful when planning your next adventure that you consider making a small donation to help keep the site running.

You can become a Supporter* (*MyHikes user account required) to unlock perks for as little as $0.83/month with a 1-time non-recurring payment 👍 Or you can simply Donate any amount without a MyHikes user account. Otherwise, telling your friends about MyHikes is the next-best thing to a donation - both quick and free 😄

Thanks for visiting MyHikes and have a great hike! ✌
