1. Los Peñasquitos Canyon Trail

Los Peñasquitos Canyon Trail is a 6.8-mile loop of majestic scenery between Rancho Peñasquitos and Sorrento Hills that leads to a volcanic rock waterfall. It’s a popular spot for hikers and mountain bikers, with scenery including year-round streams, massive live oak trees, and historical sites like Eichar’s Grave.

It’s a tranquil trail appropriate for hikers of all ages and physical abilities –– but wear proper shoes. There are many creeks, so the ground gets muddy, especially after rain. You can stay on the main trail or go off the beaten path to its many side trails. Options include a boardwalk and several creek crossings.

You may see military planes fly overhead because the park is close to the Marine Corps Air Station Miramar. Also, be on the lookout for Californian wildlife, such as Pacific tree frogs, aquatic birds, bobcats, and coyotes.

• Length: 6.8 miles
• Difficulty: Easy
• Approximate time: Just over 2 hours
• Location: Los Peñasquitos Canyon Preserve, San Diego, CA

2. Cowles Mountain Trail

Known for its spectacular views, the Cowles Mountain Trail leads to San Diego’s highest point. With an elevation of 1,593 feet, hikers marvel at the panoramic views of San Diego, Orange County, and Mexico. It’s one of the county’s most popular trails, so show up early to avoid massive crowds. Parking gets scarce at peak times.

The hike is short (3 miles round trip) but moderately difficult, so expect a good workout. Because there isn’t much shade, it gets hot; bring plenty of water. If your four-legged friends can handle the steep rocky inclines, bring them too. Just be sure to clean up after them and keep your dog on a leash.

• Length: 3 miles
• Difficulty: Moderate
• Approximate time: Just under 2 hours
• Location: Mission Trails Regional Park, San Diego, CA

3. Cuyamaca Peak Loop

If you want to go higher than Cowles Mountain, you’ll have to leave the San Diego city limits and explore the mountains of San Diego County. With an elevation of 6,512 feet, Cuyamaca Peak is the second-highest point in the county, sitting just 20 feet below the highest peak, Hot Springs Mountain. However, because Cuyamaca Peak is in the middle of the county, it offers the best views.

Located in a sparsely populated town, the park provides a more remote hiking experience. The hike features dusty tracks, dainty bridges, and hilly terrain as far as the eyes can see. As you approach Cuyamaca Peak, you may also notice the remnants of the 2003 Cedar Fire that burned many local trees.

Once you reach the top, the views are breathtaking. On a clear day, you can see up to 100 miles away, including grassy hills, mountains, and valleys. The hike is hot, moderately challenging, and sometimes muddy. Wear proper shoes and bring plenty of water.

• Length: 7.4 miles
• Difficulty: Moderate
• Approximate time: Just over 4 hours
• Location: Cuyamaca Rancho State Park, Julian, CA

5. Oak Canyon Trail

The Oak Canyon Trail features a diverse mix of natural sites and historical landmarks popular with hikers and runners. The 3.3-mile round-trip trail goes past giant live oaks, two raging waterfalls, and the Old Mission Dam which was built by Spanish missionaries in 1803. Oak Canyon is part of the Fortuna Mountain Trail Loop in the Mission Trails Regional Park.

Although moderately challenging, it’s a great family hike with a natural playground of climbing trees, river rocks, and elevated terrain. However, watch your kids closely at the waterfalls because the cliffs are very high, and the rocks are slippery when wet. The waterfalls tend to be dry in the summer, so we recommend this hike during the wet season.

Bring plenty of water, at least 1-2 liters per person, and a walking stick will ease your way through the steep rocky terrain. Additional scenery includes native wildflowers, quaint bridges, and a variety of native wildlife.

• Length: 3.3 miles
• Difficulty: Moderate
• Approximate time: 1.5 hours
• Location: Mission Trails Regional Park, San Diego, CA

Tips for Hiking in San Diego

If you’re planning to hike in San Diego, please keep the following in mind:

• Waterfall season: The best time to visit San Diego’s waterfalls is during the rainy season, from December until March. Many waterfalls dry up in the summer.

• Hydration: During the summer heat, expect each hiker to drink .5 to 1 liter of water per hour of hiking, and it’s better to have too much water than too little. I once underestimated the heat on a November hike and had to ration water. It was a rough experience for me and my entire family.

• Hiking gear: Proper attire depends on the trail and the time of year, but you generally want to wear sunglasses or a hat, sunscreen, and comfortable hiking boots.

• Poison oak: Be careful when touching unfamiliar plants. Poisonous species such as poison oak grow in San Diego’s natural areas.

• Don’t push it: If your children, pets, or family members tire, take a break or call it a day. The experience should be fun for everyone, regardless of size or physical capability.

While you’re in town, try to squeeze in a visit to the world-renown San Diego Zoo, and when you get back from your day hike, get ready to explore San Diego’s vast nightlife. Travel to San Diego for an awe-inspiring adventure with a wide variety of scenic splendors and fun-filled activities.
