At Myco Threads, we’re lucky to call San Diego home—a place where you can hit the beach in the morning and the mountains by afternoon. Whether you’re brand new to hiking or a seasoned trail runner, there’s a path here for you. We rounded up 10 of the best hiking trails across San Diego County, broken down by skill level, to help you plan your next adventure.

For Beginners

1. Torrey Pines Beach Trail Loop

Distance: 2.3 miles (loop)
Location: Torrey Pines State Natural Reserve

One of San Diego’s most iconic (and Instagram-worthy) hikes, this short loop offers stunning ocean views, sandstone cliffs, and the famous Torrey pine trees. Bonus: You can wrap up your hike with a swim at the beach below.

2. Lake Miramar Trail

Distance: 4.9 miles (loop)
Location: Scripps Ranch

A flat, paved trail that loops around Lake Miramar—perfect for walkers, runners, or anyone easing into hiking. Shady spots and picnic areas make it a great choice for families.

3. Los Peñasquitos Canyon Trail

Distance: 6.8 miles (out and back)
Location: Rancho Peñasquitos

This mostly flat trail winds through lush canyon scenery and ends at a small waterfall (yes, in San Diego!). Keep an eye out for deer, birds, and wildflowers along the way.

Moderate

4. Cowles Mountain Trail

Distance: 3 miles (out and back)
Location: San Carlos

This is San Diego’s most popular hike for a reason. It’s a bit of a climb, but once you hit the summit, you’ll score 360° views that stretch from downtown to Mexico on a clear day. Expect crowds on weekends.

5. Iron Mountain Trail

Distance: 5.6 miles (out and back)
Location: Poway

A local favorite, Iron Mountain offers a steady uphill trek with rewarding views at the top. It’s exposed, so go early or on cooler days, and bring plenty of water.

6. Potato Chip Rock via Mt. Woodson Trail

Distance: 7.4 miles (out and back)
Location: Poway

Looking for that famous photo op? This trail takes you to Potato Chip Rock, a thin slice of rock jutting out dramatically over the hillside. The trail is steep and exposed—bring your A-game and a camera.

7. Cedar Creek Falls Trail

Distance: 5.6 miles (out and back)
Location: Ramona

This one’s a stunner: a challenging trail leading to a gorgeous 80-foot waterfall. Permits are required, and it's best tackled in cooler months to avoid the intense heat.

Advanced

8. El Cajon Mountain Trail (El Capitan)

Distance: 11 miles (out and back)
Location: Lakeside

Nicknamed “El Cap,” this hike is no joke. With over 3,500 feet of elevation gain, it’s one of the toughest climbs in San Diego County. The payoff? Jaw-dropping views and serious bragging rights.

9. Three Sisters Falls Trail

Distance: 4.1 miles (out and back)
Location: Pine Valley

Don’t let the mileage fool you—this trail is steep, rugged, and requires some rock scrambling, especially near the falls. Go when water is flowing, and wear sturdy shoes.

10. Cuyamaca Peak Loop Trail

Distance: 7.7 miles (loop)
Location: Cuyamaca Rancho State Park

This high-elevation trail takes you to the second-highest peak in San Diego County. On a clear day, you can see all the way to the ocean—and sometimes even snow in the winter.

The Bottom Line

San Diego is packed with trails that offer everything from ocean breezes to mountain peaks. No matter your skill level, there’s a hike here that’ll get your heart pumping and your head clear. Grab your gear, respect the land, and as always—enjoy the trip.
