The southernmost town in the United States isn't in Florida or Texas; that distinction goes to Nā'ālehu on the Big Island of Hawaii, offering unique beach experiences. Located just under 60 miles from Kailua-Kona near the Kau coffee district, Nā'ālehu boasts a population of only around 1,000 residents. It's renowned for its local art scene, relaxed pace, and, of course, its beaches—this is Hawaii, after all. The name Nā'ālehu means "the volcanic ashes," and in the late 19th century, it was a bustling area during the height of the sugar cane industry.
There are plenty of relaxing activities and entertaining things to do on the Big Island, such as exploring charming shops and restaurants in town or visiting the local farmer's market, open on Wednesdays from 8 am until 2 pm. Here, you can purchase arts and crafts from area creators, as well as fresh fruit and baked goods. Don't miss the opportunity to explore the black and green sand beaches, as well as the cliffs at the bottom of the island, which mark the southernmost point in the entire country.
Nā'ālehu is home to the only green sand beach in the United States, the beautiful Papakōlea Beach, where the green sand comes from olivine, originating from the eruption of the Mauna Loa volcano around 49,000 years ago. This spot, located 15 miles south of the town, requires a little effort to visit. You can take a fairly easy 5-mile hike from the beach's parking lot, which is rather flat and scenic, though note that there is no shade, and it's very windy, with a climb down to the beach at the end. Remember to bring your reef-safe sunscreen, which is the only type you can use in Hawaii.
Nā'ālehu also boasts a black sand beach called Punalu'u, about nine miles away from town. The color comes from volcanic material called basalt that washed up on the beach. There are picnic tables and bathrooms, making it a perfect spot to bring lunch and spend the day. While not ideal for swimming, you can see green sea turtles lounging on the sand.
Another beautiful spot is Kawa'a Beach, a quiet black sand beach known for its good surfing when the waves aren't too rough. Snorkeling and diving are also possible when the waters are calm. A walk to the shore is required, but it's worth it. You can also see a ceremonial temple called Ke'keu Heiau on the lava flow by the east side of the beach. It's fine to observe, but do not go inside or move anything, including piled rocks, as this is a sacred space.
Ten miles away from town is South Point Park or Ka Lae, the southernmost point on the island. Here, you can observe remnants of ancient heiau or temples and watch fishermen at work off the cliffs and through holes drilled in the lava rock. While it's a perfect spot for photos and scenery, the currents are very dangerous, and swimming is not advisable.
