Whether you’re a budding astrophysicist or just a fan of Big Bang Theory, take the opportunity while you’re on the Big Island to visit the Mauna Kea Summit and Observatory.
At a lofty height of 13,796 ft (4,138 m) Mauna Kea is Hawaii's tallest mountain, and the summit is topped with astronomical observatories from around the world.
The Visitor Information Station is at a lowly 9,300 ft (2,790 m) elevation, and from here a rugged hiking trail winds to the summit. It takes around five hours and you need to be fit and prepared for all kinds of weather conditions.
The visitor center has interactive displays and videos, with interactive telescopes, talks and tours. It also runs escorted tours to the summit.
