“This remote and challenging route visits the spectacular Mauna Loa caldera area.”— Megan W
Enjoy views north across the island to Mauna Kea. Some sections of this trail are comprised of an old, two-track, jeep road. Upon reaching the caldera rim, marvel at the immense size of the crater and the forces that created it. The Observatory Trail ends at a junction with the Mauna Loa Summit Trail and Cabin Trail.
Beware of altitude sickness, bring warm clothes, sun protection, excess water and food. Expect extreme and rapidly changeable weather. To avoid getting the bends, scuba divers should not ascend Mauna Loa within 24 hours of their last dive.
