Scaled at 1:1 billion, this unique trail (longest on the West Coast, and the only one in Oregon) is a great way to enjoy the outdoors while exploring our solar system. Bike, run, walk, or skate along a 4.5-mile section (9 miles round trip) of paved path along the beautiful Willamette River discovering our sun and its planets – even dwarf planet Pluto! Then escape our solar system and visit our closest star, Proxima Centauri, and its exoplanet, Proxima b, located at Eugene Science Center.
