Located on the Big Island of Hawaii, the Hawaii Volcanoes National Park offers visitors a front-row seat to the region’s striking natural beauty. Home to everything from lush rain forest and the Halemaumau Crater to lava tubes and rolling black lava fields—where hot steam still rises from fissures and rifts that dot the rugged landscape—Hawaii Volcanoes National Park is a must on the Big Island.

Kailua Pier is a hub for fishing, snorkeling, and party boats. The pier itself is absolutely massive, an appropriate fit for one of its major claims to fame: before sunset, you’ll find captains here weighing their huge catches of the day (usually giant marlin). You’ll also spot a couple of beaches for wading, snorkeling, and diving, as well as the best views of the Kamakahonu National Historic Landmark.

The marine sanctuary of Kealakekua Bay ranks among Hawaii’s most scenic spots for snorkeling, swimming, and hiking. The beautiful bay, home to spinner dolphins and backed by green mountain slopes, was the site where Captain James Cook landed—and was later killed—on the Big Island in 1779, forever altering the history and culture of the archipelago.

Kailua-Kona, the largest town on the Big Island of Hawaii, is the epicenter of activities and tours on the Kona Coast—part of the island’s western (leeward) side. The antithesis to the lush, often rainy jungles of Hilo on the island’s eastern (windward) side, dry and sunny Kona’s activities put a huge emphasis on long days in the outdoors. Kailua-Kona is the jumping-off point for the Big Island’s best coffee-farm tours, superb reef snorkeling, all levels of hiking, and experiencing ancient Hawaiian culture, while downtown’s seaside shops and dining come with spectacular sunset views.

Visiting the Mauna Kea Summit and Observatories gives you the feeling of being on top of the world for good reason: You’re actually pretty close. Standing at 13,796 feet (4,138 meters), the mountain is Hawaii's tallest and the highlight of many visitors' trips to the Big Island of Hawaii.
