When you make your way to the east side of the island, be sure to make time for a visit to Hawai'i Volcanoes National Park. A fascinating world of Hawaiian culture, active volcanism, and environmental diversity, this park is located about 40 minutes from Hilo and it is one you simply cannot miss.
If you're looking to explore as much of the park as possible, I suggest embarking on the Crater Rim Drive, which will lead you to numerous scenic points, including volcanic craters. Make sure to keep your eyes wide for Kilauea, the world's most active volcano. Located on the eastern side of the park, this is where you can expect to find red, glowing, molten lava.
