The Story of Lower Trestles, California
Lower Trestles is the high-performance capital of American surfing: a cobblestone A-frame at the mouth of San Mateo Creek, between San Clemente and the bluffs of Camp Pendleton. Named for the railroad trestle every surfer walks under to reach it, Lowers has been poached, protected, fought over in state hearings, crowned world champions — and in 2028 it will host the Olympic Games.
The Creek and the Cobbles
The wave is built by a creek. Winter rains send San Mateo Creek — one of Southern California’s last free-flowing streams — down from the Santa Ana mountains carrying cobblestones, which it lays out in a fan delta at the beach. Offshore, a deep point of seabed bends incoming swell onto that fan like a magnifying glass. Feed it south-southwest groundswell from a Southern Hemisphere storm and the result is an A-frame that peels with mechanical evenness both ways — a marquee right, a left that equals it on the right swell line — often described as surfing’s perfectly groomed skatepark. It works year-round, but summer south swells and light morning northeast flow are what made it famous.
Poached, Then Protected
When Camp Pendleton was established in 1942 this coast became a restricted military beach, and for three decades surfing Trestles meant sneaking in — generations of surfers paid for the wave in confiscated boards and trespassing citations. The unlikely liberator was Richard Nixon, whose “Western White House,” La Casa Pacifica, sits on the bluff above Cottons Point: in 1971 his administration brokered the dollar-a-year lease that created San Onofre State Beach (renewed in 2024 for another 25 years). The next fight came from inland — a proposed toll-road extension through the state park and the creek that feeds the wave. “Save Trestles” became the rallying cry of a generation of surf activism: the California Coastal Commission rejected the road 8–2 in 2008 before a record crowd, and a 2016 settlement protected the park for good, with a $28 million conservation fund for the San Mateo Creek watershed.
The Proving Ground
The world tour has come to Lowers since 2000, when Andy Irons won the first Billabong Pro here, and Kelly Slater stacked multiple titles through the Boost Mobile and Hurley Pro years. From 2021 to 2024 the cobble fan was the WSL Finals arena — world titles decided in a single day: Gabriel Medina, Filipe Toledo twice, John John Florence; Carissa Moore, Stephanie Gilmore, Caroline Marks, Caitlin Simmers. Toledo, San Clemente’s adopted Brazilian, earned the title “king of Lowers” clinching back-to-back world championships on these walls. The town behind the trail — T-Street groms, the Andinos, the Colapinto brothers — treats the wave as its varsity field, and on April 15, 2025 it was announced as the surfing venue for the Los Angeles 2028 Olympics. Everyone still arrives the same way: on foot, by bike or skateboard down the Cristianitos trail, under the trestle, into one of the most competitive lineups on Earth.
