Volcano Hikes – Most Powerful Things to Do in Big Island

Mauna Kea Stargazing – Magical Things to Do in Big Island

For sky lovers, one of the most mesmerizing things to do in Big Island is stargazing atop Mauna Kea.

Many visitors join guided summit tours that offer sunset views followed by stargazing with telescopes at the visitor station.

The Mauna Kea Observatories are some of the most advanced in the world, and while the facilities themselves are not open to the public, the experience of watching the stars from the slopes is magical. Remember to bring warm clothing—the summit temperatures can be near freezing even in summer.

Inside the valley, you’ll find dramatic waterfalls, taro fields, wild horses, and a black sand beach backed by towering cliffs. From the Waipiʻo Valley Lookout, you can take in a stunning panoramic view without descending into the valley.

Manta Ray Night Dive – Unique 

The manta ray night snorkel is one of the most magical underwater things to do in Big Island. Just offshore from Kona, this experience allows you to float peacefully above massive manta rays that glide gracefully beneath you as they feed on plankton drawn to lights set in the water.
