Pohnpei's scuba diving is one of the worlds best kept secrets! Half the beauty of Pohnpei is underwater. The dive guides will show you fish, manta rays, and sharks - on beautiful coral reefs teeming with exotic marine life in clear, warm water. Other activities include tours to the mysterious stone city on Nan Madol and then a walk along a river to the beautiful Kepirohi waterfall. One of the nicest ways to experience Nan Madol is from kayaks that get you to hard-to-reach places. Kayaks are also available for shallow water trips through overgrown mangrove channels or for exploring the nearby reef islands. Pohnpei is a fisherman's paradise. Fly fishing and casting with lures in the lagoon passes are both popular. Or try the local style of hand-lining in the open ocean for tuna, wahoo and mahi-mahi.
