Astoria Oregon is known as the first US settlement west of the Mississippi. The tourism there has picked up over the years and one of the great perks is the Riverwalk Trail. This walkway is 5.1 miles along the river from the Riverwalk Inn to the docks were you can see the Sea Lions that have taken over. Along this path you pass under the Astoria Bridge, along the historic waterfront, and by the Maritime Museum. You can even take a trolly along this path in case you do not feel like walking.
