Discovery Lake and Trails

The Double Peak Trail from Discovery Lake offers a classic San Marcos hiking experience, starting with a gentle paved section by the lake before transitioning to a challenging dirt path. As you ascend through chaparral-covered hills, the scenery opens up, culminating in a spectacular 360-degree panorama from the 1,644-foot Double Peak summit. You'll gain 956 feet (291 metres) over 4.2 miles (6.8 km) in about 2 hours and 11 minutes, making it a moderate but rewarding climb with views stretching to the Pacific Ocean.

Planning your visit is straightforward, with ample parking and restrooms available at the Discovery Lake trailhead. The trail is dog-friendly, and the summit features amenities like picnic benches and flush toilets, perfect for a break. Due to the trail's exposure and lack of shade in many areas, especially those with burn scars, it's best to bring plenty of water and consider an early morning start, particularly during warmer seasons.

This route is one of the most popular routes in North County San Diego, known for its accessibility and the incredible payoff of its summit views. The option to choose between a paved road or a steeper dirt trail near the top allows you to customize your challenge. Keep an eye out for local wildlife, though mountain lion warnings are present, and enjoy the expansive vistas that make this one of the best hikes near Discovery Lake.
