The Interurban Trail links the Fairhaven section of Bellingham with Larrabee State Park to the south. The mixed-surface trail follows an old railway corridor on a mostly level grade, except for one steep section through Arroyo Park. The route is primarily shaded although you do get views of the water and the San Juan Islands.
From the north, begin your journey at Fairhaven Park near Donovan and 10th. (If you head west from this point, you can take the Larrabee Trail
to Bellingham Marine Park.) Heading south, however, on the Interurban, you'll wind your way through suburban back yards and city parks as well as around Chuckanut Mountain. The trail gets closer to the bay near Teddy Bear Cove, paralleling SR 11 all the way to Larrabee State Park.
You can park at Larrabee State Park (fees apply) at the southern end point at the end of Fragrance Lake Road. Parking is available at Arroya Park off SR 11 near California Street and in Fairhaven Park at the end of 26th Street. At the northern end, park off SR 11 just west of 20th Street.
