We have hiked almost all of the trails on the Island of Kauai.     Koke’e State Park has some of the best trails.     It is located on top of the mountain with many of the trails in the caldera of the extinct volcano (Wai’aleale).     The area inside the caldera is jungle, swamp and a few ridges.     The Alakai’i trail drops into the swamp and uses a series of boardwalks to traverse over to the rim on the east side.    After hiking through the swampy jungle, we arrive on a mountaintop marsh.     The trail ends at a viewpoint overlooking the Napali Coast with Hanalei in the distance.   The open marsh boardwalk is a favorite spot, one we have hiked a few times and we hope to go back to do it again.
