I live on Kauai and love exploring all the great off road trails here. One of my favorite is the trail at the end of Kuamoo Rd at the base of Mt waialeale. It's approx.4 miles long starting at the water crossing over the road. This is where they filmed parts of Jurassic park. Looking to spend some time in the next few months exploring Waimea. There are a crazy amount of trails up there. Please chime in if you are or have in the past found great trails om Kauai.
