Magnificent views over Anacortes and the islands extending into the northern Cascades.

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!

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!
