Confirmed from Mercerdale Park's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

well-maintained 4 mentions

“Pleasant, clean, and pretty elegant without being garish or performative about it, just like much of Mercer Island.”

Great playground with newer equipment- very popular with my 2yo and 5yo. Big flat grass field with paved path around. Skate park. Exercise equipment for grown-ups. I didn’t see any restrooms.

★★★★★ — Juliane , Jul 2024

Pleasant, clean, and pretty elegant without being garish or performative about it, just like much of Mercer Island. There is public art displayed and a circular walking loop, along with interesting and engaging playgrounds for children.

★★★★☆ — Joshua , Apr 2026

This is one of my favorite "local" parks. There is so much going on here for a relatively small area. First, the flat, sunny 1/4 mile loop paved trail is great for walking or kids bike riding.

★★★★☆ — Charles , Apr 2022

We absolutely love this park and walk here almost every day. It’s always clean and well-maintained, with the grass in excellent shape. You’ll often see families and groups of people enjoying walks. There’s a great playground towards the back, plus a thrift store nearby.

★★★★★ — Annie , Dec 2024

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.
