China Walls is a dramatic lava rock shoreline in Honolulu, Hawaii, known for its crashing surf, cliff jumping, and striking ocean views.
China Walls takes its name from the remarkably flat, wall-like formations of basalt lava that extend into the sea along the Portlock coastline in east Honolulu. These formations are the result of ancient volcanic activity that shaped much of the southeastern edge of Oahu, and they give the spot a geological character unlike the sandy beaches most visitors associate with Hawaii. The platform sits low to the water, which is precisely what makes it so compelling and so demanding of respect.
On calmer days, locals gather here to cliff jump from ledges that drop into deep, clear water, and snorkelers sometimes enter through gaps in the rock to explore the reef below. Bodysurfers and surfers ride the powerful shore break that wraps around the lava shelves. The surrounding neighborhood is residential and unhurried, lending the area a local, unpolished quality that feels removed from the tourist corridors of Waikiki.
There are no facilities, no lifeguards, and no formal amenities, which means visitors must come prepared and stay aware of ocean conditions at all times. The views down the coastline toward Koko Head are sweeping and unobstructed, offering a perspective on Oahu's volcanic landscape that rewards anyone willing to make the short drive out from the city. China Walls is a place that captures the elemental, unmediated side of Hawaii's shoreline.
Visit during calm summer swells if you plan to enter the water, as winter surf can make the rocks genuinely dangerous.
Wear water shoes or sturdy sandals since the lava surface is uneven and can be slippery when wet.
Arrive in the early morning to have the rocks nearly to yourself and catch the light hitting the water at its most vivid.
Bring a dry bag for your phone and valuables, as rogue waves can reach areas that appear safe from a distance.
After your visit, drive a short distance to nearby Koko Head Crater Trail for panoramic views of the coastline you just explored.
