Surfing Lower Trestles: the complete guide

Lowers isn't California's prettiest wave, nor its biggest, nor its hollowest. It's the FAIREST. A cobblestone A-frame that splits into a left and a right — the right being the better one — fast enough to reward speed, clean enough to forgive nothing on a bad line, and above all rare in its consistency. It's a wave that hands out no alibis: surf badly and everyone sees it.

That's exactly why it works as a judge. The world tour has been coming here since the 2000 season, every year since 2002, under a long succession of sponsors. Kelly Slater holds the record with six wins (2005, 2007, 2008, 2010, 2011, 2012). In 2021 the WSL ran the inaugural edition of its Finals here: a single day of competition, on 14 September, called inside a nine-day waiting window to land on the best conditions. And in April 2025 the IOC and LA28 picked Lower Trestles — over Huntington Beach — for the surfing events of the 2028 Olympic Games.

While we're at it, two corrections to what you read everywhere: the Op Pro was never held here, it was a Huntington Beach contest; and there has never been such a thing as a “Lowers Pro” — the event's current name is the Lexus Trestles Pro.

One quirk of geography catches out even the regulars: San Mateo Creek marks the county line, and Lowers falls on the San Diego County side — even though it's always associated with San Clemente, which is in Orange County.

“Trestles” doesn't name a spot, it names a whole run of them. North to south: **Cottons Point**, **Barbed Wires**, **Upper Trestles**, **InBetweens**, **Lower Trestles**, **Middle Trestles**, then **Church**. The whole thing stretches about four miles, six and a half kilometres, from San Onofre down to Cottons Point.

Lowers sits immediately south of the mouth of San Mateo Creek; Uppers, to the north. That position on either side of the creek explains their difference in character and, as we're about to see, in season.

What ties them together is the bottom: cobblestones. A cobblestone reef that produces those steady, well-drawn peaks. Middles is smaller, quite simply because it has less reef under it. And if you come in winter, bring booties — the shoreline is cobble, not sand.

Everyone repeats that the creek carries down the stones that build the bank. It's probably true and it's what the whole surf press says, but I haven't found a single geological source establishing it: take it as a plausible explanation, not as a fact. What is solid is the trio of an undeveloped watershed, a river mouth and a cobble bottom.

Finally, further south, **San Onofre Surf Beach** adds its three peaks — **The Point**, **Old Man's** and **Dogpatch** — and that's where the real answer to “what do I do if I'm not up to it” plays out (see below).

Lowers is a SOUTH swell spot. That's the most important point in this guide, because it's the one people get wrong most often.

The window is south to south-west, with SSW the ideal, carried by the southern-hemisphere swells of summer and early autumn. The offshore wind comes from the east to north-east. The useful season runs from June to October, and it's no accident that the WSL put its Finals in mid-September and that the 2028 Olympics are set for July: that's the peak of the south season.

The myth to correct: “it works on north-west swell in winter”. Not really. Off San Clemente, NW swells are cut down by 50 to 90% by the island shadow — Point Conception, the Channel Islands, Catalina, San Clemente Island. Catalina in particular blocks most of the westerly swell. In winter it's **Uppers** that takes over, and Middles also likes a west component. Put another way, along the string it isn't the season that changes: it's the peak you walk to.

On tide, we have to be honest about the state of the sources: they contradict each other. An automated generator says tide doesn't affect quality; a local guide says “low to mid and mid to high”. The two reconcile into one simple, cautious rule: **it works at pretty much all tides, avoid the extremes.**

The spot owes its name to a bridge. In 1941 the railway crossed the creek mouth on a wooden trestle bridge — a *trestle* — 858 feet long, or 262 metres. By 1951 the local surfers were calling the beach and its wave “Trestles”.

Except that bridge no longer exists. Work started in 2010 and a concrete viaduct replaced it in 2012, for eight million dollars. So Southern California's most famous spot is named after an object that's gone — and surfers still walk underneath it to reach the beach.

Which brings us to the real logistical quirk: **you don't drive to Trestles.** Access is on foot, by skateboard or by bike, along a trail. The main trailhead is the Cristianitos Road one, near the I-5 interchange. Reckon on about a mile and a half — 2.4 km — going by the official park figure from San Mateo Campground, a little under a mile from the closest parking. Call it a 1.5 to 2.5 km walk with the board under your arm, depending on where you park.

And the detail that matters for your wallet: **walking in is FREE.** The 15 dollars of day-use (20 dollars on weekends, holidays and in high season) is a PARKING fee, not an entry fee. The park opens at 6am; Surf Beach closes at 10pm from April to September, 8pm the rest of the year, and the bluff trails close at sunset. Dogs are not allowed on the beach.

The story of Trestles is the story of a stretch of water nearly lost twice over, for two opposite reasons.

**First the military.** The area borders Camp Pendleton and surfing there was long flat-out banned. Since the Marines couldn't go and fetch surfers out of the water, they confiscated the boards left on the beach and stored them on the base — the military police were still seizing them in the 1970s. Things broke open in 1971: Governor Ronald Reagan created San Onofre State Beach, which the State leases from the Marine Corps. That lease still runs. A twist of timing: around the same period, a certain Richard Nixon owned *La Casa Pacifica*, bought in 1969 at Cottons Point, at the very north of the string — the Western White House sat at the tip of the finest run of waves on the coast. He sold it in 1980.

**Then the freeway.** From 2005, a six-lane toll road project was set to cut through San Onofre State Beach. The fight lasted some fifteen years. On 6 February 2008, in front of more than 2,500 activists, the California Coastal Commission refused the coastal permit by eight votes to two; on 18 December of the same year the Department of Commerce upheld the refusal on appeal. On 10 November 2016 the transport agency dropped the project for good.

And this is where the victory becomes remarkable, because it isn't only a “no”: the settlement creates avoidance zones protecting the park and, above all, **a 28-million-dollar conservation fund** dedicated to preserving and restoring San Mateo Creek and its watershed. Which is to say, the system that feeds the wave itself. Surfers didn't just block a road: they funded the upkeep of their own spot.

One last layer of history, older than all the rest: this land is the ancestral territory of the Juaneño / Acjachemen, whose village of Panhe lies a few kilometres away. When the Olympic venue was announced, the Acjachemen nation publicly called for its recognition.

Let's be clear: **Lowers is a performance spot, not a learning spot.** Five factual reasons, not an opinion.

First, it's the wave the world's top five have been separated on since 2000 — that's no beginner's wave. Then the crowd: Trestles takes around 400,000 visits a year, and San Onofre State Beach more than 2.5 million, which makes it one of the five busiest state parks in California. On some days there are more than a hundred people spread along the peak — the spot is cited as the most crowded in Southern California after Rincon. Third, the bottom is cobble and sea urchins are part of the scenery. Fourth, you have to walk one to two and a half kilometres with your board, far from a car. Finally, the etiquette is strict and every source flags it: priority is respected, and so is patience.

But here's the excellent news, and it's what makes this park unique: **the school is three steps away.** Inside the same San Onofre State Beach, **Old Man's** is described as the county's longboard mecca, with chest-high waves peeling both ways on summer south-west swells, predictable peaks and a beginner's welcome. **Dogpatch**, right next door, is made for complete beginners and groms, with soft, slow waves. And if you want the Lowers wave without the Lowers crowd, **Church** looks a lot like it for a fraction of the people, aiming for high tide and a weekday.

So the right way to come: start at Old Man's or Church, and save Lowers for the day you know you can hold your line out there.
