Palomares Road Loop

A common and convenient starting point for this loop is the town of Sunol, which offers ample parking and is a popular hub for cyclists with amenities. This allows for easy access to the route.

The Palomares Road Loop is approximately 46.9 kilometers (29.1 miles) long. Cyclists typically complete it in about 3 hours, depending on their pace and stops.

The loop primarily follows regular roads with vehicular traffic. While sections like Dublin Canyon Road have wide bike lanes, parts of Niles Canyon Road (CA-84) have heavy traffic and narrow or missing bike lanes. Palomares Road itself generally has very light traffic, making it a more serene part of the ride. The route includes both paved and unpaved sections, with most of it being asphalt.

This route is considered difficult due to its length and significant climbs. The most challenging ascent is along Palomares Road, featuring a steep climb of about 1050 feet over 4.7 miles, with pitches reaching 9-13%. Beginners might find this challenging, but experienced road cyclists will enjoy the workout.

Cyclists can enjoy diverse scenery, including lush green hills (especially in spring), views of CA-680, and Alameda Creek. The initial segments along Foothill Road and Castlewood Drive are serene, lined with trees and large homes. Palomares Road cuts through narrow valleys with a rocky creek bed, wooded canyons, and hobby farms. A unique landmark is the Holy Cross Orthodox Monastery located along the uphill portion of Palomares Road.

The best time to cycle this route for lush green hills and picturesque views is in the spring. The weather is generally pleasant, and the landscape is at its most vibrant.

Yes, while primarily a road cycling loop, the route does briefly touch upon sections of other trails. These include the Sunol Ridge Trail, Courdet Trail, Tyler Loop Trail, Vogel Lane, Service Road, and Sunol Ridge Trail Spur.

No specific permits or entrance fees are required to cycle the Palomares Road Loop itself, as it primarily uses public roads. However, if you plan to access or spend time within Pleasanton Ridge Regional Park, be aware of any park-specific regulations or fees that might apply for certain activities or areas within the park.

As this is primarily a road cycling route with vehicular traffic, it is generally not recommended for cycling with dogs. For dog-friendly outdoor activities, consider dedicated trails or parks where dogs are explicitly allowed and safe.

For cyclists seeking a more serious workout, riding the loop in a counter-clockwise direction is suggested. This orientation can make the steep climbs, particularly on Palomares Road, feel longer and more challenging, providing an enhanced training experience.

Given the route's length and difficulty, it's advisable to bring plenty of water, snacks, a repair kit for your bicycle, and appropriate safety gear including a helmet. Sun protection is also recommended, especially during warmer months.
