Welcome to Queen Lili'uokalani Botanical Gardens. OK. So it's not really a hike. But with the small waterfall on the Nu'uanu Stream running through it, it makes a nice place for a picnic. After you finish one of the other hikes nearby (ie. Judd Trail, Kapena/Alapena Falls), this is definately a nice place to stop for lunch if you were just doing a short morning hike. On one side of the stream is the majority of the botanical gardens, and the other side is shady with lush grass perfect to throw down that picnic blanket. Or, if just relaxing with a book is your thing, there's not much better of a place in Nu'uanu. Truly a relaxing retreat from the nearby busy downtown Honolulu.
