Reef break fronting the San Elijo campground in Cardiff.
A mixed sand and rock reef throws peaky lefts and rights that peel with a slow, rippable shoulder rather than a top-to-bottom drop. It handles waist to head-high swell with rolling shape at low to mid tide, then softens as water piles on. Longboarders and shortboarders share the peaks, and steady rides make it a friendly step-up for confident surfers moving off the beach breaks nearby.

Exposure favors west and southwest swells, and the reef also picks up steep northwest energy wrapping in past Swami's. Winter, roughly November through March, brings the cleanest and most sizable days, while summer south pulses fill in the smaller sessions. Morning offshore or light east wind holds the shape, and a low to rising mid tide typically fills the reef best.
Rocks sit shallow across parts of the reef, especially at low tide, so a leash and a careful entry save fins and feet. Kelp drifts through the lineup and stinging jellyfish show up occasionally in warmer months. Crowds stack on weekends and holidays with a settled local rotation on the better peaks, so wait a turn, skip the paddle-around, and the vibe stays mellow.
The main day-use lot sits off Coast Highway 101 at the campground entrance, with a per-vehicle fee and metered street parking along the bluff. Roughly four staircases with rinse showers drop from the bluff to the sand over a three-quarter-mile stretch, each about a minute down. From the south, a ten-minute sand walk from the Cardiff Reef lot reaches the same peaks.
