Hiking
The Grant Ranch and Antler Point Extended Loop offers a demanding 20.0-mile (32.2 km) hike that immerses you in a surprisingly remote wilderness setting, despite its proximity to urban areas. You will journey through expansive oak woodlands and open meadows, with the reward of panoramic views of the Santa Clara Valley, the South Bay, and Mount Hamilton from high points like Antler Point. With 3070 feet (936 metres) of elevation gain and an estimated duration of 9 hours and 22 minutes, this route is a true test of endurance.
Be prepared for a strenuous day, as the trail features significant elevation changes and steep sections, with some grades exceeding 30%. Trails like Los Huecos and Foothill are known for their loose gravel, making descents particularly challenging. This difficult route requires careful planning and a good level of fitness, so ensure you carry enough water and supplies for the entire duration.
What makes this loop stand out is its combination of challenging terrain and diverse scenery, from grassy ridges in Halls Valley to the expansive vistas from treeless high elevations. Keep an eye out for wildlife such as wild boar and bobcats, adding to the remote feel. It is an excellent choice for experienced hikers seeking a long, rewarding day with sweeping Bay Area views.
