City of Arches on Honaunau Bay

Pu`uhonua o Honaunau National Historical Park, along with the popular snorkel spot, Pae'a (Two Step), make Honaunau Bay a popular destination. However, if you continue north up the coastline, youall find yourself away from the crowds and amid what locals call the City of Arches. This 2-mile stretch of coastline is littered with blowholes and sea arches. Blowholes are sea caves in which water is pushed vertically up through the cave, producing a blast of water much like a whaleas blowhole. The arches along this stretch are spectacular, and when the ocean is mellow itas fun to venture out onto them. The trail rambles through small shrubs for about 500 yards before dissipating. Thereafter, pick your way along the lava rock coastline without a true trail. About 2 miles in, the coastline becomes less dramatic, and most people turn around when the arches start to peter out. Because the trail is fully exposed, you can expect to get hot, but the trail ends at Pae'a, which is a fantastic snorkel spot year round. You can also enjoy Pu`uhonua o Honaunau National Historical Park, which offers restrooms and water. If you do decide to visit the national park, this is a great place to leave your car, and you can start your hike from here.
