The first two photos are from the Maha’ulepu trail which starts right next to the Grand Hyatt. It is under 2 miles each way and does not have large changes in elevation. The remaining photos are from hikes on the Kuilau trail. This is one of the easier hikes on Kauai at less than 2 miles each way. I highly recommend Kuilau. It is sometimes referred to as the trail near the arboretum.
