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.

What kind of terrain can I expect on the trail?

You'll encounter varied and often demanding terrain. The trail starts relatively flat but quickly transitions into significant climbs with grades sometimes exceeding 18% and even 'ridiculously steep' sections over 30%.

Are there any specific strategies for tackling the steep sections of the trail?

Given the 'ridiculously steep' sections with grades of 30% or more, pacing yourself is crucial. Consider using trekking poles for stability and to reduce strain on your knees, especially on descents.
