This route is generally considered a moderate road cycling trail, requiring good fitness. While it offers options for varying durations and elevation gains, making it suitable for different skill levels, be prepared for a ride that might involve up to 5 hours and significant elevation if you choose a more challenging experience.
The route primarily consists of paved surfaces, ideal for race bikes. However, it's good to be aware that some segments in the broader Strafford County cycling network can be unpaved, so depending on the exact path taken, you might encounter varied conditions.
The loop offers diverse and appealing scenery, including historic downtown areas, coastal views, and classic New England architecture. Specific highlights along the way include the Little Bay Bridge Cycle Crossing, Portsmouth Harbor, and Downtown Portsmouth.
Yes, the route incorporates sections of several other paths. You'll find yourself on parts of the East Coast Greenway (NH), the Rowe Bridge Multiuse Path, the Peter J. Loughlin Multi-Use Path, and the Pomeroy Cove Multiuse Path, among others.
The Bayside and Portsmouth loop is approximately 32.3 kilometers (20 miles) long and typically takes about 1 hour and 17 minutes to complete on a racebike, according to komoot's estimates.
The Bayside and Portsmouth loop passes through the Great Bay National Wildlife Refuge. While there are generally no specific cycling permits required for the route itself, it's always advisable to check the official Great Bay National Wildlife Refuge website for any current entrance fees or specific regulations that might apply to cyclists within the refuge boundaries.
While the route is rated as moderate and requires good fitness, its primarily paved surfaces and options for varying durations mean that easier segments are present. Families with older, experienced children or beginners with good fitness levels might find parts of it enjoyable, but it's not typically classified as an 'easy' beginner route.
Cycling in the Portsmouth and greater Seacoast New Hampshire area is generally best during spring, summer, and fall. These seasons offer pleasant weather for enjoying the coastal views and historic downtown areas. Winter cycling might be possible but can involve challenging conditions.
Specific parking information for the exact trailhead is not provided in the route data. However, given its proximity to Downtown Portsmouth and the Great Bay National Wildlife Refuge, you would typically look for public parking areas in Portsmouth or designated parking lots near the refuge entrance that allow access to cycling routes.
As a road cycling route, dogs are generally not recommended to accompany cyclists on the paved sections for safety reasons. If any part of the route enters park or refuge areas, specific leash laws and restrictions for pets would apply, so it's best to check with the Great Bay National Wildlife Refuge directly regarding their pet policies.
The route passes through Downtown Portsmouth, which is known for its vibrant atmosphere. You'll find numerous cafes, restaurants, and pubs there, offering plenty of opportunities for refreshments and breaks during your ride.
