1 / 2Mountain Playground
📍 Echo Lake, WA
Known locally as Hidden Park, Mountain Playground in Shoreline, WA offers shaded equipment, benches, a grassy picnic area, and a newly added covered shelter — making it a comfortable all-season spot.
Wait, this place is called Mountain Playground? 🤣 We've always called it Hidden Park. Anyway, my kids love this place. We walk there regularly. I like that there are benches but also a grassy area nearby if I want to bring a picnic blanket. Now that the picnic shelter is up, there's even more stuff to do!
🏆 Family Action Verdict
Best for families with children who need shade on warm days and parents who want comfortable seating nearby. The grassy area and new shelter make it a full-session park rather than a quick stop — pack lunch and stay a as.

Overview
Locals know this Shoreline spot as Hidden Park, and it has the feel of a genuine neighborhood secret. The shaded equipment is a key draw on hot Pacific Northwest summer days, keeping play surfaces cooler and extending outdoor time. Benches ring the perimeter for parents, with a grassy lawn nearby suited to picnic blankets. The recently completed covered picnic shelter adds a weather-protected gathering space — a meaningful upgrade in a rainy climate.
