Beach Days and Water Adventures
Summer is a great time to enjoy the Big Island’s beautiful coast. The Kona side has calmer ocean conditions, making it perfect for swimming, snorkeling, paddle boarding, and kayaking.
Visit Hapuna Beach State Recreation Area for soft white sand and calm waves—it’s often named one of the best beaches in the U.S. For something different, check out Punaluʻu Black Sand Beach, where you might see Hawaiian green sea turtles resting on the shore.
Snorkeling is especially good in summer, with clear water at places like Kealakekua Bay and Two Step Beach at Honaunau Bay. Both spots have colorful coral reefs full of tropical fish, so they’re great for beginners and experienced snorkelers alike.
Manta Ray Snorkeling in Kona
Manta ray snorkeling in Kona is one of the island’s most memorable activities. On this famous nighttime trip, you float on the water while manta rays swim just below you.
Calm summer waters make these tours possible, usually leaving from Keauhou Bay or Honokohau Harbor. Lights attract plankton, which brings manta rays close for an amazing show right beneath you.
Most people can try this activity, and guided tours include all the gear and safety help you need. It’s often rated as one of the best things to do on the Big Island, and it’s easy to see why.
Explore Hawaiʻi Volcanoes National Park
Be sure to visit Volcanoes National Park, which has some of the world’s most unique scenery. Summer is a great time for hiking, sightseeing, and learning about Hawaii’s volcanoes.
Take a drive on Chain of Craters Road to see old lava flows reaching the ocean. Stop at lookouts and short trails to enjoy the dramatic views.
Popular hikes include:
- Kīlauea Iki Trail: A moderate hike across a hardened lava lake
- Devastation Trail: A short, accessible walk through a landscape formed by eruptions
- Nāhuku (Thurston Lava Tube): A fascinating walk through an ancient lava tube
Check current conditions before you go, since volcanic activity can affect which areas are open. Longer summer days give you more time to see several sites in one trip.
