Rent an RV in Jacumba Hot Springs and make the short drive north to Goat Canyon - a desert landscape that’s home to the world’s largest all-wood trestle. It can be accessed along a challenging six-mile-long hike from the abandoned train station at Dos Cabezas, with the trail steadily climbing to the ridge line before descending to a dry waterfall and the bridge itself. It was constructed in 1933 as part of the San Diego and Arizona Eastern Railway after a tunnel through the Carrizo Gorge collapsed, with the new bridge made from wood (rather than metal) due to the extreme temperature fluctuations. You can also stretch your legs in the Sacred Rocks Reserve, which sprawls across a magnificent tract of high desert to the west of Jacumba Hot Springs. Soak up the panoramic views from the ridgeline or trek through the huge outcroppings of boulders before settling in at night for some of the best stargazing in California. The Oaks at Sacred Rocks also features a labyrinth based on the one at Chartres Cathedral in France and at 100 feet in diameter, is one of the largest of its kind in the state. Anglers should head directly to Lake Morena near Campo, which is stocked with largemouth bass, catfish, and trout. Non-anglers can explore one of the many hiking trails that form part of the 2,655-mile-long Pacific Crest Trail or opt to explore the water by rental boat. Be sure to stop in at the park office’s small museum, which details the region’s Native American history and the construction of the dam, before visiting the old dam keeper’s house.
