These include four routes with varying difficulty levels, from moderate to difficult, that are popular with hikers and their canine companions.
Dogs are typically welcome on trails in the surrounding open space preserves, but they must always be kept on a leash. It's essential to respect wildlife, pack out all waste, and ensure your dog is well-behaved around other hikers and animals. Always check specific preserve regulations before your visit, as rules can vary.
Yes, there are several excellent loop trails nearby that are dog-friendly. For a moderate challenge, consider the Bald Peaks Loop Trail, which offers scenic views. Another option is the Bald Peaks Viewpoint – Bald Peaks Trail Viewpoint loop from Rancho Cañada del Oro Open Space Preserve Entrance, also a moderate route.
The terrain in the area is quite varied, ranging from dirt roads and small hills to some rocky sections. You'll encounter serpentinite habitats, oak woodlands, and grey pine forests. Some routes, like the Rancho Canada del Oro and Calero Park Loop, cover significant distances and elevation changes, offering a diverse hiking experience.
While the Little Uvas Open Space Preserve itself is known for its waterfalls (like Upper, Basin, and Black Rock Falls), access is restricted. However, the broader region around the preserve features routes that incorporate waterfalls, providing beautiful natural sights for you and your dog to enjoy. Always check the specific trail details for current water levels and accessibility.
Spring is particularly beautiful, with abundant wildflowers such as California poppy and owl's clover. The weather is generally mild, making it pleasant for both you and your dog. Fall also offers comfortable temperatures and changing foliage. Summers can be hot, so early morning or late afternoon hikes are recommended, and always carry plenty of water for both of you.
The area is home to diverse wildlife. You might spot deer, various bird species (especially near the perennial ponds), and different types of butterflies. It's crucial to keep your dog on a leash to protect both your pet and the local wildlife, and to avoid disturbing their natural habitats.
For those seeking a more strenuous adventure with their dog, the Rancho Canada del Oro and Calero Park Loop is a difficult, nearly 26.5 km route with significant elevation gain. Another challenging option is the Figueroa and Cottle Loop Trail, which is also rated difficult and offers a substantial workout.
The area is highly rated by the komoot community, with an average score of 4.8 stars from 19 ratings. Reviewers often praise the diverse landscapes, the opportunity to spot wildlife, and the well-maintained trails that provide a rewarding experience for both hikers and their dogs.

Always check the difficulty and length to ensure it suits your family's and dog's abilities.
Parking is typically available at the trailheads of the surrounding open space preserves, such as Rancho Cañada del Oro Open Space Preserve. It's always advisable to arrive early, especially on weekends, as parking lots can fill up quickly. Check the specific preserve's website for detailed parking information and any potential fees.
