Banyans
reef
advanced

Banyans, along Aliʻi Drive in Kailua-Kona, is a fast, hollow reef break named after a large banyan tree that once shaded the shoreline. The wave serves up a long, powerful right and shorter left when northwest or southwest swells wrap around the island, drawing a dedicated crowd of expert surfers. Shallow reefs, sea urchins and a competitive lineup make this spot suitable only for advanced surfers.

Pine Trees (Kohanaiki)
reef
intermediate

Pine Trees, officially Kohanaiki Beach Park, is a popular surf zone north of Kailua-Kona where a series of peaks break over reef and lava rock. The spot is named after heliotrope and hau trees that resemble pines and offer shade along the shoreline. Multiple peaks provide lefts and rights that work on all tides, making it one of the Big Island's most consistent breaks for surfers of various abilities.
