Go Snorkeling and Marine Life Viewing
Snorkeling is one of the top rated things to do on the Big Island of Hawaii thanks to its clear waters and abundant marine life. The Kona coast near Kailua-Kona is especially known for excellent conditions.
Here, you can see tropical fish, coral reefs, dolphins, and even sea turtles in their natural habitat. These spots dot the coast line, many right outside your door, so check to see what’s close by before trekking too far for a good snorkel spot.

Stargaze at Mauna Kea
Stargazing at Mauna Kea is one of the most unique things to do on the Big Island of Hawaii. Rising nearly 13,800 feet above sea level, it is one of the best places on Earth for observing the night sky due to minimal light pollution.
The visitor center offers guided stargazing programs, making it accessible even if you do not drive to the summit.

Visit Black Sand and White Sand Beaches (Even Green)
Another must experience when considering things to do on the Big Island of Hawaii is visiting its diverse beaches. The island is famous for volcanic black sand and stunning white sand beaches. There’s even one of four green sand beaches in the world on the Big Island, although you’ll probably have to hike a bit to get there.
Must-see beaches include:
- Punaluʻu Black Sand Beach
- Hapuna Beach State Recreation Area
- Papakōlea Green Sand Beach
The Big Island’s beaches are heavily shaped by volcanic activity. This, combined with the Big Island’s relatively young age, creates landscapes that are completely different from other Hawaiian islands.


Explore Kona Coffee Country
Exploring coffee farms is one of the most relaxing things to do on the Big Island of Hawaii. The hills above Kailua-Kona, especially in Holualoa, are home to world famous Kona coffee.
Visitors can tour farms, sample fresh coffee, and enjoy scenic ocean views. The region is a key part of the island’s culture and economy, attracting visitors from around the world.
Other farm tours such as chocolate and vanilla are available as well.

Why the Big Island Is So Unique
The Big Island stands out because of its incredible geographic diversity. It was formed by five volcanoes and continues to grow due to ongoing volcanic activity, making it one of the most dynamic destinations in the world.
In a single day, you can explore lava fields, relax on the beach, and even experience cooler mountain climates.
