Here’s the thing about summer hiking in San Diego. The moment inland temps start creeping into the 90s, most people put their hiking boots away until October and call it a season. And honestly — for a lot of trails, that’s the right move. But the coast? The coast is a completely different story.
The Sea Cliff Coastal Bluff Trail in Del Mar is the answer to every hot summer day when you want to get outside but have absolutely zero interest in sweating through a chaparral climb in full sun. It sits right on top of the bluffs above the Pacific, gets hit with a coastal breeze almost constantly, and delivers some of the most cinematic ocean views in San Diego County — all on a flat, easy trail that almost anyone can handle.
It’s also one of those trails where the vibe matches the scenery. Del Mar is a gorgeous little coastal village with serious charm, and this trail runs right through the heart of it. Surfers below. Sea lavender lining the path. The occasional Amtrak Pacific Surfliner rumbling by on the tracks below the cliffs. Sunset views that make you feel like you’re living inside a postcard.
This is the one. Let’s get into it.

Why This Is the Perfect Summer Hike
Let’s talk about what makes this trail genuinely special in the summer, because it’s not just “nice” — it’s a legitimate game changer when the rest of San Diego is cooking.
Del Mar sits right on the coast, and the bluffs here catch ocean air almost all day long. Even when it’s 90 degrees ten miles inland, it’s routinely 65–72° on this trail with a steady breeze rolling in off the water. No shade required — the temperature just handles itself. This is one of those rare spots in San Diego where you can hike comfortably at noon in July without wanting to die.
The trail is also completely exposed to the ocean, which means there’s almost always a view of the surf below, surfers working the break, and the open horizon stretching out to the west. That combination of cool air, constant movement, and wide-open views is exactly what a hot summer day calls for.
And then there’s the summer-specific bonus: sea lavender. From late spring through summer, the bluffs along this trail light up with clusters of tiny purple sea lavender blooms — a coastal wildflower native to Southern California that grows right along the cliff edge. It turns the whole trail into something that looks almost too pretty to be real. It’s become something of a seasonal pilgrimage for photographers and plant lovers, and honestly, for good reason. Hit this trail in June or July when the lavender is in full bloom and you’ll understand immediately.
Bottom line: when the rest of San Diego’s hiking trails are either too hot, too crowded (looking at you, Torrey Pines), or require a serious commitment of time and energy — this trail is right here, breezy and beautiful and asking almost nothing of you. It’s not a workout. It’s a reset.
Where to Start and How to Get There
The best place to start the Sea Cliff Coastal Bluff Trail is at Seagrove Park, a small grassy park at the north end of Del Mar’s main beach at the foot of 15th Street. It’s a genuinely lovely starting point — there are benches under cypress trees, a direct view of the surf break below, and a laid-back park-at-the-beach energy that immediately puts you in the right headspace for this walk.
From Seagrove Park, head south along the blufftop. The trail is easy to follow — it hugs the cliff edge with the ocean to your right and the charming residential streets of Del Mar to your left. Walk as far south as you want and turn back whenever, or continue all the way to the trail’s southern terminus near 4th Street and Carmel Valley Road.
Directions to Seagrove Park:
- Take I-5 to the Via de la Valle exit heading west
- Turn left on Camino Del Mar heading south into the village
- Turn right on 15th Street toward the ocean
- Seagrove Park is at the end of 15th Street, right at the blufftop
Alternate start — the iconic train view spot: If you’ve seen this trail on social media, you’ve probably seen the photo — the railroad bridge crossing the canyon with the cliffs dropping away below it, often with the Pacific Surfliner or Coaster train in the frame. That viewpoint is near 124 S. Camino Del Mar, just south of the main village area. Many people start here instead for that shot specifically. Both entry points work great.
Parking: Easy, Free, and Low Stress
This is one of the most refreshingly drama-free parking situations of any coastal trail in San Diego. No parking pass required, no paid lots, no mad dash to beat the crowds — just free street parking in the Del Mar residential neighborhood.
Near Seagrove Park (north end): There’s free street parking along 15th Street and the surrounding blocks. It fills up on nice weekends, but the neighborhood has enough side streets that you’re rarely more than a block or two away from an open spot. Aim for 9th–16th Streets between Camino Del Mar and the bluff.
Near the south end of the trail: Street parking along S. Camino Del Mar near 4th Street is your best bet if you want to start from the southern trailhead. There are also spots along the surrounding residential streets. Paid parking is available along parts of Camino Del Mar if you strike out on free spots — it’s cheap and you won’t have to walk far.
Pro tip: If you’re coming for sunset (and you should at least once), arrive 30–45 minutes early to get a spot. The trail gets noticeably busier in the golden hour window, and parking fills up accordingly. The walk from a few blocks away is easy and flat, so even if you park a bit further than you’d like, it’s not a big deal.
Walking the Sea Cliff Coastal Bluff Trail: What You’ll See
Seagrove Park to the Sunset Seat
Starting at Seagrove Park, the trail heads south along the blufftop with the ocean immediately to your right. Within the first few minutes you’ll pass the Sunset Seat — a public art installation at roughly 130–210 S. Camino Del Mar that’s become something of a local landmark. It’s a carved stone bench positioned at one of the most photogenic overlooks on the entire trail, with sweeping views south toward Torrey Pines and north up the Del Mar coastline. Stop here. Take the photo. You earned it just by showing up.
This northern section of the trail is the most park-like — relatively wide, with benches scattered along the edge and that great cypress-framed view of the surf below. You’ll see runners, dog walkers, families pushing strollers, and people just sitting and staring at the ocean. All the right people doing all the right things.
The Sea Lavender Stretch
As you continue south, the trail narrows slightly and the vegetation closes in on either side — and this is where the magic happens from late spring through summer. Sea lavender lines the trail in thick purple-gray clusters, blooming from the cliff edge and filling the path with color. It’s not dramatic in the way that poppy fields are dramatic — it’s more subtle, more coastal, more Del Mar. On a golden hour evening the whole trail glows with it. Keep your phone charged.
The path here is hard-packed dirt and slightly uneven in places — nothing technical, just worth knowing so you’re not surprised. The cliff edge is unfenced and in some spots the erosion is active, so stay on the established trail and don’t get close to the edge for photos. The views are just as good from the path, and the cliff here is not messing around.
The Railroad Bridge and Train View
One of the most talked-about spots on this trail is the view of the railroad bridge crossing the canyon below the bluffs, near the south end of the trail. This is the spot that’s all over Instagram and TikTok — and in person it’s even better, especially when a train happens to cross.
Both the Amtrak Pacific Surfliner (running between San Diego and Los Angeles) and the Coaster (running between Oceanside and Downtown San Diego) use this line, so trains pass with some frequency throughout the day. If you want to time your visit to catch one in the shot, look up the Amtrak schedule before you head out — it takes 30 seconds and the payoff is worth it. The canyon crossing looks particularly good in the late afternoon light.
A few things to know about the railroad tracks: do not go down to the tracks. The area below the bluffs near the tracks is railroad property and is marked no trespassing. The view from the blufftop is the right place to be — you can see the bridge perfectly from up top, and it’s a much better (and legal) perspective anyway.
The South End and the Views Back North
The Sea Cliff Coastal Bluff Trail continues south past the train view toward its southern terminus near Carmel Valley Road, and the views on this section open up in a different way — looking back north you can see the full sweep of the Del Mar coastline, with the bluffs curving away and the Del Mar Racetrack visible in the distance against the hills. It’s a different angle on the same beautiful stretch of coast, and worth walking all the way to the end before turning around.
Turn back whenever feels right and retrace your steps to Seagrove Park. The whole thing is unlikely to take more than an hour, which leaves plenty of time to head into the Del Mar village for food and coffee afterward.
After the Walk: Del Mar Village Is Right There
One of the underrated perks of this trail is what’s waiting for you when you’re done. Del Mar’s main strip along Camino Del Mar is a short walk from either trailhead — a compact stretch of cafes, restaurants, and shops that manages to feel genuinely charming rather than touristy.
Darshan French Bakery on 9th Street is a local favorite with a patio and excellent pastries — perfect post-walk treat. The Del Mar Plaza, a couple blocks from Seagrove Park, has a public ocean-view patio that’s free to sit on regardless of whether you’re buying anything, which is a very Del Mar thing to offer. Several good restaurants are within easy walking distance if you want to make a full afternoon of it.
A Few Things to Know Before You Go
Stay on the trail. The cliffs here are actively eroding — sections that looked stable last year may not be this year. There’s no fencing along the edge, which is part of what makes the views so dramatic, but it also means you need to use your judgment and stay back from the edge. This trail is not suitable for young children who aren’t great at following directions around cliff edges.
Dogs are very welcome. This is one of the better dog-walking trails in San Diego — flat, breezy, interesting smells, other dogs everywhere. Keep your pup leashed; the cliff edge and proximity to the railroad tracks below make this a leash-required situation regardless of how well-trained your dog is.
Sunset here is genuinely special. The trail faces almost directly west, which means on a clear evening the sky lights up behind the ocean horizon in every direction. This is one of the best sunset spots in San Diego County, and it doesn’t require a hike to earn it. Show up, walk the bluff, watch the sun go down. That’s it.
Marine layer is a thing. Del Mar’s coastal location means fog rolls in regularly — especially in May and June (June Gloom season) and early mornings year-round. If the marine layer is thick in the morning it usually burns off by noon or early afternoon. Check the forecast and aim for the afternoon window if clear views matter to you.
The Bottom Line
The Sea Cliff Coastal Bluff Trail doesn’t ask much of you. It’s short, it’s flat, it’s free, and it delivers one of the most beautiful stretches of coastal scenery in San Diego on a silver platter. In the summer, when every other hiking trail in the county is either baking in the sun or overrun with crowds, this one is right here — breezy, purple with sea lavender, and completely underrated.
Add it to your rotation. Make it a summer evening ritual. Bring your dog, bring your camera, bring whoever you want to impress with your knowledge of San Diego’s best spots — and then take all the credit.
