A concrete walkway and a grassy picnic area sit just above two blowholes in the lava-rock reef where the surf juts through like a mini geyser. The waves can be unpredictable, so you might need to wait for some action. Eruptions are typically less than 30ft and last only seconds, but they can reach twice that height during big surf.
To get here, turn right off Poʻipu Rd onto Lawaʻi Rd and continue along the coast for less than 2 miles.
