Best Bike Path along the Columbia River in Tri-Cities, Washington I'll begin by saying that I'm not a hardcore bicyclist, I own a nice leisure bicycle made by Specialized. It's perfect for riding on paved paths and light off-road trails. It's made for trips to the store or a day trip along the riverbank of the mighty Columbia River. My pick for the best leisure bike ride in the Tri-Cities starts at Wade Park (Road 39 entrance) in Pasco and ends at Howard Amon Park in Richland - 8.25 miles one way, 16.5 miles roundtrip. There's plenty of parking at the Road 39 Wade Park entrance, so if you don't want to ride your bike to the park you can haul your bike to the parking area and start from there.
