Updated on February 7, 2020 | by Erin Sirianni

If you enjoy running and walking for exercise, you probably already experience the joy of setting out on foot on Mercer Island. Our park space and trail system provide miles to explore; our trees provide plenty of canopy to keep us cool; and our neighborhoods offer dozens of different routes and vantage points to stop for a moment to take in a scenic view.

With the exception of the occasional swooping owl in Pioneer Park, it’s a pretty good place for a quick or leisurely jaunt.

We hope you enjoy this essential guide for runners (and walkers)! We’ve included some of our favorite walking and running routes, a round-up of local running events, a must-read book for finding neighborhood cut-throughs and hidden trails, and more!

Where to Run (and Walk) on Mercer Island

Mercer Island offers over 475 acres of park space and over 50 miles of maintained trails, making our island a trail runner and hiker’s delight. The largest local parks offering the most trail mileage are Luther Burbank Park, Aubrey Davis Park, and Pioneer Park, as described below. We’ve also created the following running maps for you to use to inspire your next walking, running, or hiking route.

Aubrey Davis Park

Aubrey Davis Park, also known as “Park on the Lid,” is an expansive park built on top of I-90 to protect the nearby neighborhoods from freeway disturbances. It features paved paths that are popular with runners, walkers, and bikers. Enjoy city and lake views and wide open spaces as you run through this park. The route below will also take you past Mercer Island’s Outdoor Sculpture Gallery located along the I-90 corridor on Sunset Highway between 77th Ave SE and 80th Ave SE.

Luther Burbank Park

Luther Burbank Park is located on the northeast shore of Mercer Island and runs three quarters of a mile along the waterfront. The route below will take you past wetlands, dairy barn ruins, a dog park, an earth sculpture called “The Source,” an amphitheater, as well as through the woods of upper Luther Burbank Park. As Mercer Island’s most popular park, you can expect to share the path with families, dog walkers, beach goers, and other runners and walkers along the way.

Pioneer Park

Pioneer Park, located at the south end of Mercer Island, has three different quadrants offering 6.6 miles of trails winding through 113 acres. The northeast quadrant is our favorite, and if you follow the Ravine Trail, you’ll eventually discover the bridge (pictured below) that crosses a natural stream through the park. As I mentioned earlier, runners should watch out for swooping owls, especially at dawn and dusk in the fall. The route below starts at Starbucks in the south end shopping center and will take you around the perimeter of all three quadrants.

South End Trails Loop

(Island Crest Park / Parkwood Open Space / Pioneer Park)

If you’d like to experience a variety of different trails and neighborhoods, we’ve included the following route, which begins and ends at Island Crest Park. This loop will take you down to East Mercer Way through Parkwood Open Space and back up to Island Crest Way via SE 53rd St Open Space, as well as behind Island Park Elementary School and through the quadrants of Pioneer Park before returning back up Island Crest Way to Island Crest Park.


If you don’t mind hills, almost every neighborhood on Mercer Island is runner and walker friendly. If you’d like to avoid hills for a flatter route, you might enjoy running in Mercer Island’s mid-island and south end neighborhoods. The Lakes neighborhood, for example, is flat, and offers an approximate one-mile easy-running and walking loop. If you’re looking for a five-mile neighborhood route, here’s one of our favorites through the neighborhoods of Parkwood, Island Point, and the Lakes.


There are two tracks on Mercer Island – both popular with runners and walkers. One track is located at Islander Middle School and is easily accessible to anyone who wishes to use it almost any time of day. Parking is available after school hours at the middle school. The other track is located at the Mercer Island High School.  This is a beautiful, enclosed track, only accessible if you have a facilities key card. Members of the Mercer Island community are invited to use the track but must purchase a key card annually for $5 at the Mercer Island School District’s Maintenance and Operations building.

Must-Read Resource

When I was training for my first half-marathon, I was always looking for new running routes around Mercer Island as I began to tire of my usual loops. Walk! Mercer Island became my indispensable resource. I used it to figure out new routes and to find hidden trails that connected different neighborhoods that I wanted to loop through. The book contains a Trail Guide section, a Guided Walks section (i.e. East Seattle History Loop), and a From Here to There section (i.e. Mercer Island High School to Town Center walk).  In the introduction, the author Kris Kelsay states that “Walk! Mercer Island is intended to bring the island alive for people on foot.” This book does just that.

Running & Walking Groups


Twice a week, the Bluebirds women’s running group gathers at local parks on Mercer Island, led by Desiree Berry, a former professional triathlete and runner (who also recently qualified for the US Olympic Trials with a 2:39:17 time at the Cal International Marathon!). The group meets on Mondays and Wednesdays, and workouts consist of either hills, circuit training, interval running, or a fartlek, followed by a cool-down of stretching and a bit of core work. All abilities are welcome, and each runner takes her own pace on nearby park trails and loops. Learn more on the Bluebirds website.
