6. Natural Bridge-Caverns at Natural Bridge are the deepest caverns on the East Coast and go 34 stories underground below the earth's surface to see nature's magnificent underground landscape of dripstone, flowstone, draperies, pools, stalactites, and stalagmites.
Location: Between PuÊ»upoa and Makahoa Points, Hanalei. Description: Hanalei Bay, the largest bay on KauaÊ»i, is bordered by a white sand beach approximately two miles long and 125 feet wide. The beach is located between Hanalei River to the east and Waipa River to the west.
Between mile markers 13 and 14 on the Hana Highway you will have a chance to visit Honomanu Bay. There are two roads that lead to the beach. The first is about a half-mile beyond the 13 mile marker-but this dirt road brings you out on the wrong side of the beach (the stream will cut you off from the remainder of the shoreline). The other access road is available just beyond the 14 mile marker. This route is much muddier, steeper, and 4x4 may be required at times so you might have to walk to the beach instead. Taking your car off-road is a violation of your rental agreement anyway.
