If you love to breath fresh air then the hikes through the jungles of Hawaii are something you'll want to do. The island of Oahu has some of the best hikes and many are accessible for all levels. One of our favorites is Maunawili Falls in the windward slopes of the Ko'olau mountains. The hike starts off from a neighborhood off one of the roads leading from the Pali Highway as you drive into Kailua. The path is well marked and covered in foliage most of the way as you wind your way up moderate hills along a stream, ultimately leading to the source of the stream, one of the most beautiful waterfalls on Oahu! At the bottom of the waterfall is a fairly deep pool that people sometimes swim in. Be careful the area can be slippery and muddy especially after a lot of rainfall. You'll likely not be alone on this hike as it's one of everyone else's favorites too!
