Overview: This short hike will take you to 100ft Manoa Falls. The trail can be quite muddy, so make sure to wear proper shoes (you will be sorry if you wear flip flops, because your toes will easily slip around once they get muddy.
Several scenes from the TV show LOST were filmed here, as was parts of Jurassic Park (you can see posters in the building with bathrooms and food service).
Unfortunately, you cannot swim in the pool at the base of the waterfall, but the view alone justifies the easy hike.
Tips: Parking costs $5 at the parking lot, or you can take the #5 bus which stops just before the entrance, on the residential streets. You can also park on the residential streets and walk about 1/4 a mile in.
You can park in the parking lot, or take the #5 bus to the Arboretum and Manoa Falls trailhead.
Start your hike here past the sign to Manoa Falls. You gain a little elevation as you walk to the base and may feel as if you are on the set of Jurassic Park, which was filmed in this area.
