You can typically find parking near the access points to the San Francisco Bay Trail or the Ravenswood Trail, particularly around the Ravenswood Open Space Preserve or Bedwell Bayfront Park. These areas often have designated parking lots for trail users.
The loop offers a varied terrain, which is great for gravel biking. You'll encounter a mix of surfaces, including gravel roads, some paved sections, and unpaved portions with loose gravel and packed dirt or sand. Within the Ravenswood Open Space Preserve, the trails are generally flat and follow marsh levees.
Yes, this loop is generally considered easy and very suitable for beginner gravel bikers. The overall flatness of the San Francisco Bay Trail in this area, combined with minimal elevation changes, makes it accessible for riders of all skill levels.
You'll enjoy stunning views of the San Francisco Bay and surrounding areas. A major highlight is the Ravenswood Open Space Preserve, a 376-acre wetland known for exceptional birdwatching. Expect to see a variety of migrating birds like sandpipers, avocets, and herons, and potentially even endangered species such as the Ridgway's rail.
The trail is enjoyable year-round, but spring and fall often offer the most pleasant weather for gravel biking, with mild temperatures and less chance of extreme heat or heavy rain. These seasons are also excellent for birdwatching as migratory species are abundant.
Yes, the trail is generally dog-friendly. However, as parts of the route pass through the Don Edwards San Francisco Bay National Wildlife Refuge and other preserves, it's crucial to keep dogs on a leash at all times to protect the sensitive wildlife and natural habitats.

While the immediate trailside areas are primarily natural preserves, you can find cafes and restaurants in the nearby towns of East Palo Alto, Menlo Park, and Redwood City. These towns are just a short ride or drive from various access points to the loop.
Given the varied terrain and potential for sun exposure, we recommend bringing plenty of water, sun protection (sunscreen, hat, sunglasses), a basic bike repair kit, and layers of clothing. Binoculars are also a great idea for birdwatching in the Ravenswood Open Space Preserve.
