They’re technically separate beach parks but sit next to each other about four miles past the Hilo post office, which is why you’ll hear this area referred to as “Four Mile.” Although Kealoha and Carlsmith don’t offer those traditional long stretches of Hawaiian white sand , they have plenty of room to enjoy a variety of activities. While you’re there, try snorkeling, paddleboarding, tidal pools, and picnicking in the grassy areas. The eastern side of the bay, closer to Carlsmith, is sheltered and calm, thanks to outcroppings of reef and lava rock. However, the western side of the bay is exposed to the ocean, offering possibilities for boogie boarding and surfing in the right conditions.
