San Juan Island is a perfect place for road biking, with its charming towns, mix of open and shaded roads, and spectacular ocean and mountain views. This loop takes in the best attractions on the northern half of the island. Climbing the hill from the ferry dock takes you through Friday Harbor, the largest town in the San Juan Islands. The next segment crosses the open fields and pastures of the island's central valley. On the far side of the valley is a fragrant and picturesque lavender farm. Next, as you round the bend to the west, an amazing vista of Haro Strait and Vancouver Island comes into view. Shortly after is a worthwhile stop at Lime Kiln Point State Park, famous for its old lime kiln, lighthouse, and orca whale viewing. The route then heads north through the British Camp section of San Juan Island National Historic Park, where you can learn about the infamous "Pig War" between the U.S. and Great Britain that started in 1859. Continue north to the village of Roche Harbor and its interesting sculpture park, then return to Friday Harbor on one of the island's main roads.
