Maguire Peaks Loop Trail in the Sunol Regional Wilderness offers a delightful escape for dog owners and their dogs. Spanning approximately 4 miles, this scenic loop is the longest trail in the park, providing a unique opportunity to explore diverse landscapes and enjoy breathtaking views of the San Antonio Reservoir, the Ohlone Wilderness, and the majestic Mount Diablo. As you traverse the trail, you and your dog will encounter a variety of rare plant species that are hard to find elsewhere in the park, making this hike not only a physical journey but also a chance to appreciate the beauty of California’s natural flora.

One of the great aspects of Maguire Peaks Loop Trail is the flexibility it offers to dog owners. Dogs are welcome on the trails, provided they remain under complete voice control. This policy allows for a more enjoyable hiking experience, as you can let your dog explore the surroundings while maintaining their attention. However, it’s important to keep in mind that the area is rich in wildlife, including deer and various birds, so if your dog is prone to chasing, it’s advisable to keep them leashed for their safety and the safety of local wildlife. Remember to bring bags to clean up after your dog, as maintaining the beauty of the trail is a shared responsibility.

To access the trail, you’ll need to obtain a parking permit at the visitor center and then drive to a small parking lot at the trailhead on Welch Creek Road. A nominal fee of $2 per dog applies, so have that prepared. While there is no water available along the trail, it’s crucial to bring plenty of water for both you and your dog, especially during the warmer months. Spring is considered the best time to visit, as the weather is mild and the wildflowers are in full bloom, creating a picturesque backdrop for your adventure. The combination of shade from oak trees and open ridgeline sections means you’ll experience varied terrain throughout the hike.
