Hanalei Bay Beach (swimming, snorkelling, bodyboarding, surfing, windsurfing ++)
Hanalei Bay on the north shore is a large circular bay, with more than 2 miles of clean white sandy beach backed by mountains, said to be the most scenic setting in the Hawaii islands. It is also one of the best recreation beaches in the island. Loads of ocean activities include kayaking and sailing. There are 3 beach parks with facilities in this bay, Black Pot Beach Park, Hanalei Pavilion Beach Park, and Waiolli Beach Park. The beach is exposed to high surf during the winter. Beware strong currents.
Ke’e Beach (swimming, snorkelling)
The tropical-looking Kee Beach, located at the western end of Na Pali Coast State Park on the North shore of Kauai, is the best snorkeling spot in the island. Its shallow lagoon offers great swimming, especially for families with children. The beach can have high surf during the winter, sometimes summer as well. Beware strong currents.
Poipu Beach Park (swimming, snorkelling, bodyboarding, surfing)
Kauai island is loaded with unspoiled beaches, some secluded and only accessible by boat (such as Honopu Beach or Kipu Kai Beach). Poipu Beach Park is not only one of the great Hawaii beaches, but it is also packed with things to do and places to see. It is known for its unique shape and excellent swimming beach, especially for families with small children, because the lava borders create a sheltered pool with still, shallow water. A few blocks from Poipu Plantation is good for snorkelling due to the calm, clear waters and plenty of colourful fish . Because of its popularity, this coral beach can be crowded. Beware high surf during summer. A more isolated place, a couple of miles east is Mahalepu Beach with a wild beauty. Swimming is not quite as easy as Poipu Beach, but the views are sensational.
Secret Beach, Kauapea, is absolutely gorgeous but quite tricky to get to (15 minutes walk down a dirt road off ‘one’ (south or east!) of the Kalihiwai Roads, near Kilauea town) and the surf/sea is VERY powerful and unsafe.
