Hawaii Volcanoes National Park is a large park. There are about 30 miles of trails. I will post different parts of it separately.
Holie Sea Arch is an impressive rock formation, about 90 ft high. It was cut into the cliff of an ancient lava flow. A few steps from the parking lot at the end of the Chain of Craters road lead to the edge of the cliff where you could see the arch and feel the power of wave which created the remarkable formation.
