The John Nicholas Trail offers a diverse jogging experience, transitioning from smooth singletrack through lush canyon woods to more advanced, rocky terrain at higher elevations. You'll pass towering redwood giants and the picturesque Lake Ranch Reservoir, eventually reaching a vista point with expansive views of the South Bay. This difficult 9.4-mile (15.2 km) route involves 1388 feet (423 metres) of elevation gain and takes about 1 hour and 54 minutes, making it a substantial challenge for trail runners.
This popular trail is well-constructed and heavily used by both joggers and mountain bikers. Parking can fill up quickly, so plan to arrive early, especially on busy days. While generally accessible, some initial climbs can be a little rocky and steep, and higher sections feature extremely tight switchbacks. Always carry sufficient water, particularly during warmer periods.
The trail is notable for its purpose-built design, including a 3-mile singletrack section originally for mountain biking, and unique features like well-built footbridges and a hand-constructed stone culvert. It connects to the broader Bay Area Ridge Trail system, offering a glimpse into the region's diverse ecosystems from creek-side forests to high-elevation madrone and spruce groves.

The John Nicholas Trail is located within Sanborn County Park. You can typically find parking within the park itself, which provides direct access to the trailhead. Specific parking areas are usually well-marked.
Yes, the trail is dog-friendly! However, it's important to keep your dog on a leash at all times while on the trail, as per park regulations.
The trail offers a pleasant experience year-round due to ample shade from the woodland. However, spring and fall often provide the most comfortable temperatures for jogging. Wildflowers can be seen in spring, adding to the scenery.
Sanborn County Park, where the John Nicholas Trail is located, may have entrance fees or parking fees depending on the day and time. It's advisable to check the official Santa Clara County Parks website for the most current information on fees and any specific regulations.
The terrain is varied. It often starts as a wide, relatively flat dirt fire road for the first 1.5 to 1.9 miles. After Lake Ranch Reservoir, it transitions to a narrower, smooth singletrack, though you might encounter some uneven sections with small rocks or roots. Expect a gradual overall climb with distinct steeper sections, and several well-built footbridges.
The trail winds through pleasant woodland with oak, redwood, fir, pine, and bay laurel trees, offering plenty of shade. A notable highlight is the picturesque Lake Ranch Reservoir. As you gain elevation, you'll see madrone trees and Douglas fir, with large rock formations. Near the end, a Viewpoint and Picnic Spot offers pleasant, though somewhat limited, vistas of the South Bay, Mount Diablo, and Oakland.
You might spot various wildlife such as deer, rabbits, skunks, ducks, frogs, and egrets. The trail is also an excellent spot for birdwatching, with opportunities to see species like the Pileated Woodpecker and Pacific Wren.
Yes, the route is part of the larger Bay Area Ridge Trail system. It also intersects with other paths, including sections of the Lake Ranch Trail and the Skyline Trail.
While the initial fire road segment is relatively easy, the trail is generally rated as difficult for jogging due to its length and significant elevation gain. After Lake Ranch Reservoir, the trail narrows and includes steeper sections, with some segments reaching a 10-15% grade. Beginners who are not in good physical shape may find certain segments demanding.
Yes, there are a few interesting features! Keep an eye out for an "autographed" tree stump left by the California Conservation Corps staff who helped build the trail. You might also spot an overturned Volkswagen Beetle about 10 yards off-trail. A section with sharp, short switchbacks has even earned the nickname "Lombard Street."
The John Nicholas Trail is a popular route, especially on weekends. If you prefer a quieter experience, consider visiting on weekdays or earlier in the morning.
