The crown jewel of South Kona is undoubtedly Kealakekua Bay. This beautiful bay is part of a marine reserve and is home to beautiful coral and an amazing array of tropical fish. Dolphins are commonly seen here as they use the sheltered bay as a place to avoid predators and to sleep.
On the south side of the bay is Napoʻopoʻo Beach, a small beach where access to the water is easy, though there are no lifeguards and limited facilities.
On the north side of the bay is Captain Cook’s Monument. To access the monument you’ll need to hike down from Napoʻopoʻo Road. Read more about this hike in our blog post about top hikes on the island here. The north side of the bay is where the best snorkeling is located and you’ll find that the tour boats typically congregate here.
There are tour operators offering snorkeling and kayaking tours, or you can rent kayaks yourself. This means you can kayak across the bay, and snorkel off the kayak (we’ve done it and we recommend this, especially if you aren’t keen on hiking down to, and back up from, Captain Cook’s monument).
