    Route Description for Mount Diablo Hike

    The Mount Diablo Trail is a must-hike when in the Bay Area. This famous trek attracts thousands of eager adventurers weekly, so expect to share the trail. Those seeking a more secluded adventure are encouraged to head out on weekday mornings for a more tranquil experience. The exposed terrain offers dumbfounding views while warranting unbearably warm conditions, so avoid the trail on hot days and head out at dawn for more manageable weather. Drink and pack plenty of water to stay hydrated, approximately 1 quart every 2 hours. Note that Mount Diablo State Park charges a $10USD entrance fee.

    Indulge yourself in the beauty of the Californian landscape along the Mount Diablo Hike. This wonderful adventure, though demanding, rewards its tired conquerors with unrivaled views of the Bay Area, the Cascade Range, the Santa Cruz Mountains, the Sierra Nevada, and more. Head out after a rainy winter and enjoy the scene of the slopes covered with wildflowers and lush vegetation, including canyon larkspur, warrior’s plume, western wallflower, sagebrush, and Coulter pine. In addition to a diversity of flora, this route also offers the opportunity to spot lizards, snakes, white-tailed kites, mountain lions, black-tailed deer, and more.

    When your water bottle is filled, and your hiking boots are tied, you can begin your adventure along the Mount Diablo Trail from the South Gate Trailhead. Setting out from here, wander along the Summit Trail, which runs parallel to Summit Road, for the first segment of the adventure. Gradually ascending through the lush meadowlands, you will be rewarded with stunning views of the neighboring Diablo Mountains and the cityscape below. Soon after your departure, the path will redirect you northeast, intersecting with several merging trails and Summit Road—stay on the Summit Trail.

    The further you climb, the better the views. Admire the wildflowers that flank the footpath and the lush chaparral and oak woodlands that cloak the terrain. Be mindful of rattlesnakes, and keep your eyes peeled for wildlife! As you near the summit, the grade will intensify, leading you up to the Summit Building. Hike up the spiral staircase to the observation deck, where you will notice ancient marine fossils embedded in the sandstone walls. You will be treated to 360-degree views of the rolling hills, the broad valley, the Bay Area, and distant views of soaring crests from the observation deck. Appreciate the unparalleled panoramas, and when you are ready, retrace your footing back down the path to the trailhead.
