The Absolute Best Hikes in San Diego 

San Diego has some of the best weather in the country and a diverse landscape just waiting to be traversed. One day you can be hiking rocky cliffs overlooking the Pacific, and the next you could be climbing the Laguna Mountains or exploring desert canyons. Discover the absolute best hikes in San Diego, ranging from easy to challenging.

1. Mission Trails Regional Park

This recreational park is one of the most popular hiking areas in San Diego, featuring 8,000 acres and 60 miles of trails. While this pick contains multiple trailheads, we couldn’t pick just one hike! We felt the entire trail-filled regional park was worth including. There are trails for all hiking levels, from flat and short paths to steep, long, and challenging hills. Dogs are allowed, but they must be kept on a leash due to the wildlife in the area. Be on the lookout for coyotes, rattlesnakes, and mountain lions. There are also campgrounds and a lake for boating and fishing.

2. Cowles Mountain Trailhead

Located within Mission Trails Regional Park is the Cowles Mountain Trailhead, one of the best hikes in San Diego. It is a scenic uphill climb with breathtaking panoramic views at the summit. Take in the smell of wildflowers as you ascend over 900 feet. The trail is a three-mile out-and-back route, which takes about an hour and a half to complete. The hike is moderately challenging, with an uphill, steep, and rocky climb. This is a very popular area, especially in the early mornings. 

3. Tecolote Canyon Natural Park

The Tecolote Canyon Trail is inside a natural park near the University of San Diego. This popular dog-friendly hike is moderately challenging, featuring flat and hilly portions. It winds through neighborhoods, tree-lined paths, and canyons, steadily rising in elevation (to about 400 feet). The trail is out-and-back, with a total length of 6.7 miles. On average, people spend over two hours on the trail. Dogs and children are welcome but keep them away from the trail edge as there are many poison oak and coyote sightings.

4. Penasquitos Creek Waterfall

Starting at Penasquitos Creek Park, the path down to the waterfall and back is roughly six miles. While the route is relatively easy, it can take a total of two hours to complete. It is an excellent choice for beginners who want some solitude. This trail is not very busy and features plenty of shaded areas along the creek on a flat trail. Watch out for poison oak, snakes, and mountain bikes! Dogs are also allowed on leash. Be sure to check for closures before heading out, as this area often floods during storms. 

5. Black Mountain Open Space

Black Mountain features over 2,300 acres of hills, canyons, and ridges. It’s a popular spot for hiking and mountain biking, with multiple trailheads leading to a central peak with a panoramic view. If you avoid the weekends, you can have a more relaxing and peaceful experience. Depending on the trail you choose, you can experience an easy stroll or a challenging and steep climb. It’s a dog-friendly area but be sure to bring lots of water for you and your furry pal. Additionally, bring adequate sun protection, as the trails don’t offer much shade.  

6. Los Penasquitos Canyon Preserve

The Canyon Trail in Los Penasquitos Canyon Preserve is an easy loop route. However, it is almost seven miles and takes over two hours to complete. It is a popular area for hiking, biking, and wildlife viewing. Despite its length, the trail offers a leisurely stroll, making it kid and dog friendly. It has beautiful scenery and many birds, so if you love a good nature walk, you will appreciate the Canyon Trail. This trail eventually leads to the Penasquitos Waterfall. However, you don’t have to venture this far.

7. Sunset Cliffs Coastal Trail

For something different, check out the Sunset Cliffs Coastal Trail atop the Pacific Ocean bluffs. It’s an excellent spot for a sunset walk, featuring incredible views and opportunities for whale watching. Just be sure to stay away from the cliff edge. It’s a busy area where people come to walk, sit, and read. And the trail is an easy out-and-back route, taking about 45 minutes to complete the 2.4 miles. While not technically a hike, this coastal trail is an excellent urban nature walk.
