10 Best Running in Seattle (Costs & Tips, 2026)

It costs nothing to use and the loop stays flat for the full 2.8 miles, which is exactly why this is the default answer any Seattle runner gives when asked where to go — separate lanes for walkers and runners exist because the path gets that packed on a sunny weekend.

A wide paved path, no fee to use, runs along West Seattle's only real beach, with the downtown skyline visible across Elliott Bay for most of the route — genuinely the closest thing Seattle has to a California-style beachfront run. It stays flat enough end to end that pace is limited only by how crowded the path gets in summer.

The full trail runs over 20 miles end to end, but the stretch between Fremont and Sand Point — flat, paved, free to use — is the section most runners actually use, running close enough to Lake Washington and the ship canal that the water is rarely out of view. It's a genuine multi-use path, so expect cyclists and commuters sharing it at rush hour.

The 2.8-mile Loop Trail through the city's largest park, free like every other route on this list, stays genuinely wooded for most of its length, then opens onto bluff-top views of the Puget Sound and Olympic Mountains right when the forest starts to feel repetitive. Real hills throughout make this a step up in effort from the flat waterfront options elsewhere on this list.

A 2.4-mile paved loop, free to run any time of day, circles a peninsula that somehow still holds old-growth forest inside Seattle's city limits, one of the last stands left after the rest of the area was logged over a century ago. Flat throughout, and Mount Rainier shows up across Lake Washington on a clear day without you ever leaving the loop.

A straight, flat, free waterfront path runs north from the Olympic Sculpture Park along the edge of Elliott Bay, close enough to downtown to start the run right from a hotel but quiet enough once you're on it that it doesn't feel like an urban route. Grain-terminal ships loading nearby are a strange, genuinely Seattle thing to watch mid-run.

An Olmsted-designed park loop, no admission required, with just enough gentle grade to feel like real running rather than a flat commute, past a working 1906 water tower whose observation deck is free to climb for a break partway through. It sits close enough to Capitol Hill's coffee shops that a post-run stop practically writes itself.

Dense forest and a genuinely quiet dirt-and-gravel trail, free to run like everything else here, sit almost unnoticed between Capitol Hill and Montlake, which keeps this one of the least crowded wooded runs anywhere close to downtown. The tree canopy means it stays noticeably drier underfoot during Seattle's lighter rain than the fully exposed waterfront routes.

Where Alki up the road is pure flat beach promenade, this park mixes a forested interior trail with a paved seawall path along Puget Sound, plus the saltwater Colman Pool at the south end for a post-run swim in summer. No cost either way, and the two terrains inside one park make it feel like two different runs depending on which loop you take.

A former naval air station turned into one of the city's largest parks at no cost to visit, with a lakefront loop quiet enough that off-leash dogs at the adjacent dog park are often the only other company on the trail. Flat the whole way, and Lake Washington stays in view for most of the loop without the Green Lake-level crowds.
