7 min read Checked October 7, 2026

San Diego rides year-round, from flat fire roads to a 10-mile backcountry descent. Pick a trail by skill level below, check what's closed, stay off trails for 48 hours after rain, and carry more water than you think.

Affected trails, since June 2026 fire

The short version

  • Beginners: Mission Trails' Grasslands Loop (1.2 miles, nearly flat) or the Daley Ranch fire roads; advanced: Noble Canyon's 10.3-mile descent
  • Affected trails in Los Peñasquitos Canyon Preserve were still closed in mid-September 2026 after the June 9 fire; call 858-538-8066
  • The San Diego Mountain Biking Association asks riders to stay off most trails for at least 48 hours after significant rain
  • County rangers say to carry a liter of water for every 2–3 miles; inland trails get extremely hot by afternoon
  • Moment Bicycles in Old Town rents full-suspension mountain bikes; most beach-area rental shops only have cruisers

San Diego has year-round riding, but three things trip up visitors and new riders: which trails allow bikes at all, which areas are closed right now, and how long the clay soil takes to dry after a storm. Start with your level, then check the details for each trail below.

Pick a trail by skill level

Beginner

  • Mission Trails: Grasslands Loop
  • Daley Ranch fire roads
  • Lake Hodges North Shore

Wide dirt roads and little climbing. The Grasslands Loop is 1.2 miles and nearly flat. Start here if you're new or on a rental.

Intermediate

  • Daley Ranch: Boulder Loop
  • Black Mountain: Miner's Ridge Loop
  • Sycamore Canyon / Goodan Ranch

Singletrack, steady climbs and loose rock. Boulder Loop is 2.5 miles with about 380 feet of climbing.

Advanced

  • Noble Canyon
  • Black Mountain: Summit Trail
  • Mission Trails peak climbs

Technical, rocky and remote. Noble Canyon is 10.3 miles point to point, so you need a shuttle car.

ClosedLos Peñasquitos Canyon Preserve. Affected trails were still closed in mid-September after the June 9, 2026 fire. Call the ranger office at 858-538-8066 before you go.

The rule nobody tells you: stay off wet trails

San Diego's trails are clay-heavy and rut badly when wet. The San Diego Mountain Biking Association (SDMBA) asks riders to give most trails at least 48 hours after any significant rain, and its rule of thumb is blunt: "If you can see your tracks, TURN BACK." San Dieguito River Park, which manages the Lake Hodges trails, asks for the same 48 hours. SDMBA also rates every trail area on how fast it dries, from 1 (rideable the day after rain) to 10 (three weeks or more).

SDMBA wet-trail ratings, checked October 7, 2026. These are guidance, not closures; land managers post closures separately.

1. Mission Trails Regional Park

The default first ride, starting from the Visitor Center off Father Junipero Serra Trail. Bikes are allowed only on trails the park map marks as multi-use or hiking-and-biking. The speed limit is 10 mph, riders yield to hikers and horses, and helmets are required under 18. For a first ride, the Grasslands Loop is 1.2 miles with minimal climbing, reached from the Mast Boulevard / East Fortuna staging area. The climbs around the peaks get technical fast. Hiking instead? See the 5-Peak Challenge.

2. Daley Ranch, Escondido

3,201 acres and more than 25 miles of multi-use trails, open dawn to dusk, with the main entrance on La Honda Drive and a north entrance on Valley Center Road. Its fire roads dry faster than almost anything else in the county. The step up is the Boulder Loop: 2.5 miles and about 380 feet of climbing on doubletrack, rideable in either direction. The City of Escondido says Caballo Trail isn't recommended for bikes right now; rangers are at 760-839-4680.

3. Lake Hodges North Shore

A gentle stretch of the Coast to Crest Trail along the lake, good for a first ride on dirt. The catch is drainage: SDMBA rates it 7 of 10 for dry-out time, so after a real storm it can stay muddy for days.

4. Black Mountain Open Space Park

Miner's Ridge Loop is a 2.5-mile moderate loop from the parking area on Black Mountain Road. The Summit Trail, from the Oviedo Way cul-de-sac, is steep. About 10 miles of easier regional trails run toward Santaluz.

5. Sycamore Canyon and Goodan Ranch, Poway

A County preserve with more than 10 miles of trails between Poway and Lakeside. The main staging area is at 16281 Sycamore Canyon Road, with a second on Highway 67 in Lakeside; vehicle access is 8 a.m. to sunset. The north end dries quickly (SDMBA 4), the south end slowly (8).

6. Noble Canyon, Cleveland National Forest

San Diego's classic backcountry descent: 10.3 miles point to point, mostly downhill, from the Penny Pines trailhead on Sunrise Highway to Pine Valley, so you need a shuttle car. It's rocky, technical and remote. E-bikes aren't allowed on the singletrack, and hiking guides report that parking at the Pine Valley end needs an Adventure Pass ($5 a day or $30 a year). Guided rides run here too (see below).

Renting a mountain bike, or riding with a guide

  • Moment Bicycles, Old Town (1891 San Diego Ave, 619-523-2453): rents carbon full-suspension mountain bikes, booked online. Pick up from 5:30 p.m. the day before and return by 5 p.m.; if trails are wet, the shop may cancel with a refund.
  • Trek Bicycle North County, San Marcos (1617 Capalina Rd): rents Trek Rail full-suspension e-mountain bikes, booked through rentabikenow.com. Handy for Daley Ranch and Lake Hodges.
  • Guided rides: XEN MTB (socalbiketours.com) runs guided rides at Daley Ranch, Noble Canyon, Laguna Meadows and Cuyamaca, which also solves the Noble Canyon shuttle problem.
  • Skip the beach rental stands for this: the ones we checked in Mission Beach and La Jolla rent cruisers and e-bike tours, not mountain bikes. None of the shops above publishes a daily price, so ask when you book.

Trail manners and safety

  1. 01

    Yield to hikers and horses

    It's the posted rule at Mission Trails, along with the 10 mph limit. Riders heading downhill also yield to those climbing.

  2. 02

    Stop completely for horses

    SDMBA asks riders to stop completely for horses and move to the downhill side of the trail to let them pass.

  3. 03

    Watch for rattlesnakes

    California Fish and Wildlife says most bites happen April through October, when snakes are most active at dawn, dusk and night. If you're bitten, get to a hospital: no tourniquet, no ice, no cutting. Poison Control is 800-222-1222.

  4. 04

    Check conditions before you drive
