Best San Diego CA Bike Trails for 2026
Contents
Search for the best San Diego CA bike trails and you get one undifferentiated list: a paved bay path next to a ten-mile backcountry descent, both tagged “easy access, great views.” Those are not the same decision. Before you load the car you need three things about any ride here: whether the surface is asphalt or dirt, whether the gate is open when you arrive, and whether rain or a permit rule closes the place first.
No single agency owns the riding here. Paved regional paths are built segment by segment by SANDAG. A canyon preserve might belong to the City of San Diego, the County, Escondido or a water district; the mountains belong to the Cleveland National Forest. Each sets its own hours, bike rules and closure policy, which is why a trail that looks perfect on a crowd-sourced map turns out to be gated at 5 p.m., off-limits to e-bikes, or behind a military permit.
Key takeaways
- SANDAG says the Bayshore Bikeway will eventually extend 24 miles around the bay, not that it already does. The San Diego River Trail is the same.
- The San Dieguito River Park publishes a trail-by-trail table of which of its 65-plus miles allow bikes. Several of its easiest trails do not.
- Gates close early: West Sycamore at 5 p.m. outside daylight saving time, Sycamore Canyon and Elfin Forest at or near sunset.
- Elfin Forest closes for moderate or heavy rain and Red Flag Warnings, and bans e-bikes past the parking area.
- Noble Canyon needs an Adventure Pass; bikes are banned outright at Blue Sky Ecological Reserve in Poway.
Paved paths: Bayshore Bikeway and the San Diego River Trail
If you want asphalt and a flat grade, the two names that come up are the Bayshore Bikeway and the San Diego River Trail. Both are worth riding, and both are incomplete.
SANDAG’s project page says the Bayshore Bikeway “will eventually extend 24 miles around the bay,” built from a plan adopted in 2006 and funded through TransNet. The finished pieces are specific: 1.8 miles between Palomar and H streets in Chula Vista, done in 2012; a 0.6-mile Harbor Drive extension between 32nd and Vesta streets, 2015; and a one-mile separated path along Harbor Drive in National City, early 2018. A 2.3-mile Barrio Logan segment on Harbor Drive between Beardsley and 32nd streets joins two finished stretches; SANDAG began it in May 2022 with a target opening of July 2025, so check its current status. Treat the bikeway as excellent car-free stretches joined by on-street connective tissue.
The San Diego River Trail is more clearly unfinished. SANDAG builds it in segments as funding and right-of-way become available, and two planned pieces are not open: the Santee path between West Hills Parkway and Mast Park, handed to a private developer to build alongside a golf-course redevelopment, and the Mission Valley stretch from Fenton Parkway toward Rancho Mission Road, which got as far as a route study before SANDAG suspended work in 2018. Ride the pieces that exist on the ground, and check the date on any corridor map, because a line on it is not a path.
Lake Hodges and the San Dieguito River Park
For dirt without a technical penalty, the San Dieguito River Park is the most useful resource in the county, because it publishes what most sites will not: a table of every trail with mileage, difficulty and a yes-or-no column for biking. It reports more than 65 miles open year-round for free day use, including 49 miles of the planned 71-mile Coast to Crest Trail.
Staging area hours catch people out: gates open daily at 6:00 a.m. and close at 6:00 p.m. from October 1 through March 31, or 7:30 p.m. from April 1 through September 30. The David Kreitzer Lake Hodges Bicycle Pedestrian Bridge keeps its own hours, 6 a.m. to 9 p.m.
| Trail (San Dieguito River Park) | Miles | Difficulty | Bikes allowed |
|---|---|---|---|
| Coast to Crest at North Shore Lake Hodges | 7.65 | Moderate | Yes |
| Coast to Crest at San Pasqual Valley | 8.85 | Moderate | Yes |
| Coast to Crest at Del Dios Gorge | 2.27 | Moderate | Yes |
| Piedras Pintadas Trail | 2.20 | Easy | Yes |
| Highland Valley Trail | 2.10 | Easy | Yes |
| Bernardo Mountain Summit Trail | 1.95 | Strenuous | Yes |
| West Bernardo Drive Bike Path (paved) | 0.46 | Moderate | Yes |
| Crest Canyon Trail | 1.15 | Easy | No |
| Dust Devil Nature Trail | 1.70 | Easy | No |
| Clevenger Canyon South Trail | 3.60 | Strenuous | No |
North Shore Lake Hodges is the segment the park itself flags as a mountain bike trail, and at 7.65 moderate miles it anchors a half day. Note that difficulty and bike access do not track each other: strenuous Bernardo Mountain Summit is open to bikes, while easy Crest Canyon and Dust Devil are closed to them.
Dirt near the city: Mission Trails, West Sycamore and Goodan Ranch
The City of San Diego describes Mission Trails Regional Park as over 8,000 acres with about 60 miles of trails, roughly eight miles northeast of downtown. It is large enough that the useful move is picking an entrance rather than “going to Mission Trails,” and bike access varies trail by trail.
West Sycamore is the entrance most worth knowing for riders. The park puts it at 1,128 acres with seven miles of trails, reached from the far east end of Stonebridge Parkway in Scripps Ranch at 17160 Stonebridge Parkway, with a large lot and a portable restroom. The gate hours are the catch: 8 a.m. to 5 p.m. in fall and winter, 8 a.m. to 7 p.m. during daylight saving time.
It connects directly to the County’s Sycamore Canyon/Goodan Ranch Preserve, 2,272 acres with more than 10 miles of trails. Vehicle gates at the Goodan Ranch Staging Area (16281 Sycamore Canyon Road, Poway) and the Highway 67 Staging Area (13920 Highway 67, Lakeside) run 8 a.m. to sunset daily.
Common mistake
The roughly four-mile Stowe Trail along the preserve’s eastern edge runs on MCAS Miramar land, and the permit comes from the air station’s Provost Marshal’s Office, not the County. It is a background-checked permit requiring a form, a witnessed liability waiver and an in-person visit, so it is not something to arrange on the morning of a ride. Riders who link it into a loop from a downloaded GPX file are on permitted ground without the permit. Sort that out before the ride, not at the boundary sign.
North county dirt: Daley Ranch and Elfin Forest
Daley Ranch in Escondido is a 3,201-acre conservation area the city acquired in 1996, with over 25 miles of multipurpose trails across six main routes, open dawn to dusk. The city calls out the Boulder Loop at 2.4 miles and the Ranch House Loop at 2.5 miles. The main entrance is at 3024 La Honda Drive, just north of Dixon Lake.
Two advisories matter to cyclists: the Caballo Trail from the staging area to the Sage Trail is in poor condition and not recommended for bikes, and rangers have been directed to cite riders for off-trail travel, a misdemeanor under municipal code section 18-76. Call the Dixon Lake Ranger Station at 760-839-4680 if a line’s legality is unclear.
Elfin Forest Recreational Reserve, run by the Olivenhain Municipal Water District, is 784 acres with approximately 11 miles of trails open to hiking, mountain biking and horses. It opens at 8 a.m. and closes about 30 minutes before sunset daily except December 25, and vehicles left after gate lock are towed. Two rules trip riders up: it closes for moderate or heavy rain and for Red Flag Warnings, and e-bikes count as motorized equipment, barred beyond the parking areas.
The backcountry option: Noble Canyon
The Cleveland National Forest lists Noble Canyon Trail, number 5E04, at 10 miles one way, or 15 with the Big Laguna Trail connection. The Forest Service rates it strenuous, calls it a full-day outing, and describes ledge-hugging switchbacks, steep slopes and jagged rocks where finishing may require some walking. It also calls the Big Laguna to Noble Canyon connection one of the best rides in Southern California.
From the same source: an Adventure Pass is required to park at the Noble Canyon Trailhead, and the recommended seasons are fall, spring and winter, which is the Forest Service telling you not to attempt it in a Laguna Mountains summer. The upper end is 13.5 miles north of I-8 on Sunrise Highway near Pine Valley, just past the second cattle guard. The lower end is 1.2 miles north of Pine Valley on Olde Highway 80, then 1.6 miles on Pine Creek Road. Call the Descanso Ranger District at 619-445-6235 for conditions.
Pro tip
Check official use designations rather than assuming a connection is legal. The Forest Service page for the Big Laguna Trail, a 10-mile loop with about 1,000 feet of gain, lists only hiking under recreation opportunities, even though the neighboring Noble Canyon page praises the linkup as a ride. When two official pages disagree, the ranger district settles it.
Rules that change your day
Poway’s published rules, covering more than 78 miles of trails, are a good model for the county: bikes yield to hikers and equestrians, the speed limit is 10 mph at Lake Poway and 15 mph elsewhere, off-trail travel is prohibited, and trails run sunrise to sunset. Poway also states flatly that bicycles are not allowed at Blue Sky Ecological Reserve, the 598-acre state reserve managed by the Department of Fish and Wildlife — a popular trailhead and a common wrong turn.
Two more preserves belong on the list. Otay Valley Regional Park has 8.3 miles of non-motorized multi-use trails from the San Diego National Wildlife Refuge to I-805, with a ranger station at 2155 Beyer Boulevard. Los Peñasquitos Canyon Preserve covers roughly 4,000 acres across about seven miles, from the I-5 and I-805 merge to just east of I-15, with east-end access off Black Mountain Road; call 858-538-8066 for trail status after flooding.
Frequently asked questions
Which San Diego bike trails are fully paved?
The completed segments of the Bayshore Bikeway, plus short connectors like the 0.46-mile West Bernardo Drive bike path. The San Diego River Trail is still a corridor rather than a continuous route, so treat any single stretch of it as unconfirmed until you have checked. Because both regional trails are delivered in pieces, confirm your intended segment on the SANDAG project pages before planning a point-to-point ride.
Where should a beginner ride dirt for the first time?
The San Dieguito River Park’s easy-rated, bike-legal trails are the gentlest introduction: Piedras Pintadas at 2.20 miles and Highland Valley at 2.10 miles are both listed as easy and open to bikes, and the park publishes a map for each.
Do I need a permit or a pass to ride?
Most city and county preserves are free day use. Two exceptions stand out: an Adventure Pass to park at the Noble Canyon Trailhead, and a valid County permit for the Stowe Trail beside MCAS Miramar.
Are e-bikes allowed on San Diego County trails?
It depends entirely on the land manager. Elfin Forest classifies electric bicycles as motorized equipment and bars them beyond the parking areas. A rule at one preserve tells you nothing about the preserve next door, so check the specific agency’s page.
What happens to the trails after rain?
Closures, in several places. Elfin Forest closes for moderate or heavy rain and for Red Flag Warnings, and Los Peñasquitos Canyon trails may close for flooding. Riding saturated dirt also cuts ruts that outlast the storm, so a rain day is a paved-path day.
When is the best season to ride here?
Cooler months are easier on the coastal and canyon preserves, but gates close earlier: San Dieguito River Park staging areas shut at 6 p.m. from October through March, and West Sycamore at 5 p.m. outside daylight saving time. For the mountains, the Forest Service names fall, spring and winter for Noble Canyon. Poway warns that some popular trails are dangerous in heat, worth taking literally on inland dirt in late summer.
