The New Stretch of San Clemente's Beach Trail Was Built for the Railroad

Since Friday, October 9, the San Clemente Beach Trail runs its full 2.3 miles from North Beach to Calafia again. The section that reconnects it, at Mariposa Point north of Casa Romantica, came out of a $93 million project to protect the rail line. About $24 million of that went to the trail itself, and the walk north of the pier now follows the railroad's needs in where it runs and what stands beside it.

What the $93 Million Paid For

The Orange County Register's report on the ribbon-cutting describes the main structure as a catchment wall nearly 1,400 feet long and 10 to 20 feet tall. Its job is to keep rocks, soil and debris from the coastal bluff off the railroad track. The Orange County Transportation Authority's project page puts the wall on the bluff side of the tracks, running from the El Portal Beach access point to Linda Lane. The same page lists restoring the Beach Trail as part of the project.

The wall exists because of the railroad. The LOSSAN Rail Corridor through town carries Metrolink and Amtrak Pacific Surfliner passenger trains, plus freight and military traffic. According to the Register, rail service through San Clemente has been interrupted several times since 2021 by bluff failures, beach loss, erosion and worn-out shoreline protection. OCTA CEO Darrell Johnson told the Register the project was about "taking action now to protect the rail corridor while working closely with the city and community to preserve access to the coast." The rail corridor comes first in that sentence, and it came first in the budget.

Construction started in September 2025. OCTA's project page still shows its first estimate that work would run through summer 2026. The ribbon-cutting came in early October, after OCTA's October 6 release said the Mariposa Point work was finishing that week.

The Bridge Is Gone, and the Path Now Runs at Track Level

The old route crossed the Mariposa Bridge, a steel-and-wood span. The Register says a 2024 landslide knocked it down, and in November 2025 another active landslide closed the northern part of the trail. The project removed what was left of the bridge and reconnected the trail on a ground-level route next to the railroad.

So the Mariposa stretch now runs at track level, with the new wall on the inland side. Register photos taken October 5 show the finished ground-level trail beside the wall north of Casa Romantica. The wall is tinted to match the colors of the hillside. On opening morning, one regular walker told the Register she would miss "the cute little iconic rickety bridge, such a nostalgic piece of our little San Clemente," and in the same breath called the new section beautiful.

Older trail guides that send walkers to Mariposa by way of the bridge are now out of date. Mayor Rick Loeffler called the full shoreline route "the treasure of San Clemente, going from one end to the other, looking at this beautiful ocean." Walking it end to end now means walking right beside an active rail line through Mariposa Point.

Which Posted Rules Matter Most on the New Stretch

The City of San Clemente's Beach Trail page posts the current rules. With the trail now running right beside the tracks at Mariposa Point, the rail-corridor rules carry particular weight there.

• Rail corridor. OCTA owns the corridor. The City says pedestrians must stay on the trail, cross only at designated railroad crossings, and never go into the corridor itself.
• E-bikes. No e-bike of any class is allowed on the trail or the beach. That applies even with the motor switched off.
• Pedal bikes. Riders must yield to pedestrians, stay under 10 mph, and walk their bikes through the marked Walk Bike Zones.
• Dogs. Leashes must be six feet or shorter. Dogs aren't allowed on the beach. The City provides waste bags and bins along the trail.
• Hours. The trail is open 4 a.m. to midnight. The exception is the stretch from the south T-Street restrooms to Calafia Beach, which is open 6 a.m. to 10 p.m.

Accessibility is still unclear. The City's page lists the ADA-accessible sections as North Beach to Mariposa and Linda Lane to the Pier. That leaves out the rebuilt section between Mariposa and Linda Lane, and the page doesn't say whether the new section qualifies. Metrolink's guide calls the trail flat and accessible to wheeled travelers along its whole length. If you use a wheelchair or a stroller, ask the City whether its accessibility list now covers the Mariposa stretch.

Walk One Way, Ride the Train Back

Because the trail parallels the tracks for its full length, the one-way walk with a train ride back works again. Metrolink's trail guide lists two stations on the route: "San Clemente," which locals call North Beach, at the north end, and San Clemente Pier, at 1850 Avenida Estacion, in the middle. The Pier station is open only on weekends. Both stations are on the Orange County and Inland Empire–Orange County lines.

Metrolink's own suggestion is to arrive at the North Beach station and leave from the Pier station. Depending on which segments you combine, a walk can run anywhere from 1.0 to 4.5 miles. Since the Pier stop only operates on weekends, this plan is a Saturday or Sunday outing. Check the schedule first. Metrolink's service updates showed an Orange County line shutdown on October 10 and 11, which was the trail's first weekend back.

One Saturday with something else going on in town is October 24. The San Clemente Downtown Business Association's Treat Street runs from 4 to 7 p.m. that day, with participating businesses along Avenida Del Mar and El Camino Real.

More Coastal Work Is Coming at the South End

The Mariposa reopening wraps up one section of the rail work. OCTA's project FAQ says its board on September 28, 2026 authorized the CEO to take the necessary steps, including issuing procurements, for an engineered shore-protection structure south of San Clemente State Beach and for sand placement at three locations in San Clemente. The FAQ also says the schedule for the Area 4 revetment work, also south of the State Beach, hasn't been set.

The City has its own sand project in the works. A staff report for the September 1, 2026 City Council meeting describes a planned fall 2026 SCOUP project of about 5,000 cubic yards of sand. The report says that project is still being developed and that the next Army Corps of Engineers replenishment cycle is planned for 2029/30. None of these documents gives dates for any effect on public beach access. For the coming months, the Calafia end of the trail is the stretch to watch for the next round of rail work.
