haleakala sunrise 1
The main feature of this part of the park is undoubtedly the famous Haleakala Crater. It is huge: 6.99 miles (11.25 km) across, 2.0 mi (3.2 km) wide, and some 2,600 ft (790 m) deep. The interior of the crater is dotted by numerous volcanic features, including large cinder cones. Two main trails lead into the crater from the summit area: the Halemau'u and Sliding Sands trails.
Each morning, visitors come to the summit of the volcano to watch the spectacular sunrise. More visitors come each afternoon to watch the equally amazing sunset. In either case conditions can be extremely cold.(Wikipedia)
