Maha’ulepu Heritage Trail, Kauai
Enjoy a 4-mile out-and-back hike along the last stretch of accessible coastline of Kauai’s south shore that hasn’t been developed. The Maha’ulepu Heritage Trail is an easy hike from the southeast corner of Keonela Bay (also known as Shipwrecks) to Kawailoa Bay along sand dunes, limestone formations, and rocky inlets that offer safe haven for sea turtles and the endangered Hawaiian monk seal. Take a moment at the Makauwahi Sinkhole, a portion of the largest limestone cave found in Hawaii.
Cerro el Coronel, Baja California
Start near the beach on this nearly 7-mile hike up the Cerro el Coronel, where views range from Point Loma, California, to Todos Santos Island in Baja California. Bring along plenty of water for your journey, and scan for the best hiding place for a treasure trove of gold—because legend has it that the colonel’s stash remains hidden since the early 1800s.
