The best family-friendly hikes and walks in San Bernardino National Forest

Embark on a dramatic journey through multiple climate zones on the San Jacinto Peak and Round Valley Loop. You'll traverse dense pine forests and meadows in Round Valley, where wildflowers bloom in spring, before ascending to exposed, rocky terrain. The highlight is undoubtedly the summit of San Jacinto Peak, offering spectacular 360-degree panoramic views of the Coachella Valley, Salton Sea, and distant mountain ranges.

This difficult 7.6-mile (12.2 km) hike involves a substantial 2433 feet (741 metres) of elevation gain, taking approximately 3 hours and 58 minutes. Access is typically via the Palm Springs Aerial Tramway, which significantly reduces the initial climb. Remember that a free day-use wilderness permit is required beyond the Long Valley Ranger Station, and high altitude can be a factor, so plan accordingly.

What makes this trail truly notable is the dramatic transition from desert landscapes to alpine wilderness in a single day, especially when using the tram. The area is part of the Mount San Jacinto State Park, a high-elevation wilderness offering a cool escape from the desert heat. Keep an eye out for wildlife like mule deer and mountain chickadees, and appreciate the historical significance of the CCC-built cabin near the peak.

The San Jacinto Peak via Devil's Slide Trail offers a dramatic ascent into the San Jacinto Wilderness, starting amidst dense pine forests and transitioning to rugged, rocky terrain. You'll navigate numerous switchbacks on the Devil's Slide Trail, eventually reaching Saddle Junction before the final, boulder-strewn push to the 10,834-foot summit. The reward for this difficult 7.5-mile (12.0 km) hike, with its 4221 feet (1286 metres) of elevation gain, is an expansive panorama that can stretch all the way to the Pacific Ocean and Catalina Island.

To tackle this approximately 4-hour and 30-minute journey, you'll need a day-use permit from the Idyllwild Ranger Station, especially if you're hiking on a weekend between Memorial Day and Labor Day when permits for the Devil's Slide Trail are limited. Parking at Humber Park also requires an Adventure Pass. Always check for seasonal conditions, as snow and ice can persist at higher elevations, making winter hiking on San Jacinto Peak via Devil's Slide Trail a different challenge.

This route is a significant access point into the San Jacinto Wilderness from Idyllwild, offering a prime way to experience Southern California's alpine beauty. Along the way, you'll intersect with the iconic Pacific Crest Trail, and near the summit, an emergency hut provides shelter. It's considered a good first major mountain for those with solid fitness, showcasing a unique blend of forest, meadows, and dramatic granite topography.

Embark on a moderate hike along the Champion Lodgepole via Castle Rock Trail, a 6.6 miles (10.6 km) route that takes about 3 hours and 10 minutes to complete. You will gain 1025 feet (312 metres) in elevation, starting with a climb to Castle Rock. From this vantage point, you can enjoy wide views of Big Bear Lake and the surrounding mountains. The path then winds through towering evergreen trees and past large granite boulders, leading you to the majestic Champion Lodgepole Pine, a truly ancient tree.

Be ready for a steep initial climb to Castle Rock, where some boulder sections can be tricky to navigate. Parking at the trailhead is limited, so plan to arrive early, especially if you are hiking during peak times. If you visit in winter, expect significantly more challenging conditions due to snow and ice, and be sure to bring specialized gear like micro spikes and trekking poles.

This popular trail is nestled within the San Bernardino National Forest, offering a diverse experience with several natural landmarks. The highlight is undoubtedly the Champion Lodgepole Pine, recognized as one of California's largest and oldest lodgepole pines. You also have the option to extend your hike further to explore the tranquil Bluff Lake Reserve, adding more to your day in this scenic area.

Embark on the Cougar Crest Trail, an easy hiking route that guides you through varied scenery in the San Bernardino National Forest. You will wander through shaded forests of pine and oak, which gradually give way to more open areas offering expansive views of Big Bear Lake and the surrounding mountains. This out-and-back trail covers 2.7 miles (4.4 km) with an elevation gain of 798 feet (243 metres), typically taking about 1 hour and 19 minutes to complete.

When planning your visit, be aware that an Adventure Pass is often necessary for parking directly at the Cougar Crest Trailhead. If you prefer not to purchase a pass, you can find free parking at the nearby Big Bear Discovery Center. From there, it's just a short walk to reach the trailhead and begin your hike. Consider starting your adventure earlier in the day to enjoy cooler temperatures and fewer crowds.

The Cougar Crest Trail offers more than just scenic views; it also provides a unique connection to the legendary Pacific Crest Trail (PCT). As you hike, you will encounter the point where the two trails intersect, giving you a small taste of this epic long-distance route. This makes the trail a great option for those curious about the PCT or looking for a well-maintained path with a notable connection.
