Check out Twin Falls.

Your first stop on the Road to Hana is Twin Falls.  This is the perfect way to start your journey down the Road to Hana. You can park in the convenient lot, right on the side of the road, and walk just a few steps down a trail to the recreation area where they have picnic tables and  a restroom!  The lower fall is an easy walk on a flat trail, and the pools surrounding it are lovely.  There are many enjoyable aspects of the Twin Falls recreation area, and the lower fall is one that can be enjoyed by almost everyone. Check with Hana Picnic Co for more information and directions.
