There are beaches that are well known as "nude", "topless" or "clothing-optional" in Hawaii. Non-lewd, non-sexual nudity on Hawaii's beaches is legal. However, nudity of any kind is forbidden on state park beaches even if you find a secluded spot for sunbathing. And, some communities have a policy against nude sunbathing and sporadically enforce it.
There are many beaches in Hawaii no located in state parks that are secluded enough and quiet enough that you can enjoy some time sunning without your bathing suit. Some well-known unofficial clothing-optional beaches on four of the Hawaiian islands are places you'll easily find nudity even though local policies may discourage it.
Honokohau Harbor Beach, Big Island of Hawaii
The north end of this yellow sand beach is a popular gay beach. Privacy is difficult to find here, and Federal Park rangers often patrol to enforce a ban on nude sunbathing.
However, with its warm climate and good snorkeling, this remains a very popular nude beach.
Kehena Beach, also known as Dolphin Beach, Big Island of Hawaii
This is a well-shaded black-sand beach protected by steep cliffs and tall trees. Swimming can often be hazardous due to rough current and high waves. It is a popular beach for local residents.
Donkey Beach (Kuna Bay), Kauai
Donkey Beach, named after the donkeys that used to transport sugar cane, is located 7/10 of a mile north of mile marker 11 on Highway 56 on the island of Kauai. It is not visible from the road.
Access to the beach is via a path through the Kealia Kai housing development. Look for the public parking area up a small hill from the roadside. (All beaches in Hawaii are public beaches.)
You can also reach the beach by means of the new Ke Ala Hele Makalae coastal bike/hike path. Park at Kealia Beach and enjoy a beautiful 1/2 walk north along the path to Donkey Beach at Kuna Bay.
Donkey Beach was known as one of Kauai's best nude beaches, however, the Kealia Kai developer has hired security guards to patrol the area and enforce a no nudity policy.
Secret Beach also known as Kauapea Beach, Kauai
Secret Beach, also known as Kauapea Beach, is accessed by hiking a trail at the end of a red dirt road off of Kalihiwai Road, which is found about a half mile north of Kilauea on Rt. 56.
This has now become Kauai's premier nude beach, although County authorities attempt to enforce a nudity ban.
Secret Beach is a long, yellow sand beach which offers beautiful scenery. Swimming in winter is not advised due to high surf, but at other times of the year, excellent snorkeling can be found here.
Little Beach at Makena (Pu'u Ola'i Beach), Maui
Little Beach at Makena (Pu'u Ola'i Beach) is Maui's unofficial clothing optional beach. Little Beach is adjacent to Makena Beach (Big Beach,) but is inaccessible by car. Drive to Makena Beach which is located a few miles past the Maui Prince Hotel along Makena Ala Nui road.
Park at the paved parking lot and walk to the beach. Theft from cars is common here, so remove your valuables from your car. At the northwest end of the beach, there is a path up the lava rocks that takes you over the outcrop to Little Beach. This is perhaps the best spot in Hawaii for nude sunbathing. The swimming and snorkeling are excellent.
Red Sand Beach in Hana also known as Kaihalulu Beach, Maui
Red Sand Beach in Hana (Kaihalulu Beach) is one of Hawaii's prettiest beaches, but it is difficult to reach. The remains of a caved-in cinder cone have created the beautiful cove in which this crescent-shaped beach is found.
Drive to the Hana Community Center on Ua Kea Road, next to several cabins which are part of the Hotel Hana Maui. You will need to walk on private property to reach the beach. You can park on the street nearby.
At the south end of the Community Center is a path that passes an old cemetery. The path crosses to the shoreline and up and along the face of the outside of the cinder cone. The path is narrow and footing is poor.
At the end of the path, you'll find the Red Sand Beach. Swimming and snorkeling are excellent. The water is calm and clear. This is a very small beach but one which should not be missed.
Papohaku Beach, Molokai
The island of Molokai has no beaches which are unofficially designated as clothing-optional. Molokai is the least visited of the main Hawaiian Islands—not including Kaho'olawe which is closed to the public.
This is not to say that you will not be able to find a long stretch of beach that will be yours alone and provide an opportunity for nude sunbathing. Often when visiting Molokai, on a beach such as Papohaku Beach, one of the world's longest beaches you'll walk along for three miles and see no one on the beach. If you want a private, secluded and beautiful beach, Papohaku is for you.
