Rainbow Bridge offers views to La Conner and Shelter Bay from above the Swinomish Channel. There is a little walkway on either side so you can enjoy the views without worrying about traffic.

The waterfront is filled with quaint coffee joints, pubs, seafood restaurants, and cafes. There are public restrooms across from the rib house. A promenade takes you along the water with views of the docks.

Tommy Thompson Parkway is a great car-free route out to March Point, with nice water views along the trestle. But heads up—seagulls drop shells here to crack them open, leaving sharp debris that’s notorious for causing flats. Ride with caution, and if you’re on skinny tires, consider walking your bike across the worst sections.

This quarter-mile trestle bridge spans Fidalgo Bay, giving elevated views of the water and surrounding landscapes. However, this area is also a dining area for local gulls, who drop clams onto the bridge to crack them open, leaving behind sharp shell fragments that can litter the path. While the city occasionally sweeps the trail, watch your step.

99% of my bike rides utilize this route out of Anacortes. Beware the flying clams!

Roadside lake in the Anacortes Community Forest Lands. People fish, swim, hike and bike here. Maybe horsies too. May be tainted by toxic algae in the summer months - check before you swim or let your dog swim.

The trestle provides a car-free route to March's Point, BUT there is a downside. Sea gulls use the trestle to crack open clams, dropped from above, and the pointy shards litter the trestle until the sweeping angels come. I've punctured many times here, and ruined a couple of expensive bike tires. I wish there was some kind of "Shell Report" or webcam or some way of knowing the condition of the trestle before you head out on your bike. And if I wanted to walk my bike across the trestle, I wouldn't have ridden a bike.

You can leave the bland roadside trail and ride along the waterfront, behind Anthony's. Just watch out for peds!

Another excellent choice is the Quarry Pond loop from Cranberry Lake Swim Beach, which is 14 km long and also rated easy.

Can I cycle directly on Skagit Island Marine State Park?

No, Skagit Island Marine State Park itself does not have cycling trails directly on the island. The island is accessible only by boat, and once there, visitors explore on foot via a land trail. Touring cyclists typically integrate a visit by cycling to a mainland watercraft launch point, such as Cornet Bay in Deception Pass State Park, and then transitioning to human-powered watercraft like kayaks to reach the island. The surrounding Skagit Valley and nearby islands, however, offer numerous road biking routes with diverse scenery.

What is the best time of year to enjoy no-traffic touring cycling in this region?

The best time to enjoy touring cycling in the Skagit region is generally from late spring through early autumn (May to October). During these months, the weather is typically milder and drier, making for more pleasant riding conditions. You'll also experience the region's natural beauty, including fields of flowers like purple camas on Skagit Island, if you plan a multi-modal trip.

For example, routes involving the Tommy Thompson Parkway are generally close enough to Anacortes to access dining options before or after your ride. For more remote routes, it's always best to pack your own provisions.

What should I bring for a no-traffic touring cycling trip in this area?

For a comfortable no-traffic touring cycling trip, it's recommended to bring essentials such as water, snacks, a basic bike repair kit (including a pump and spare tube), appropriate weather-dependent clothing layers, sun protection, and a helmet.
