Pine Lake

🏊Swimming at Pine Lake

Pine Lake is a shallow, warm suburban lake with a designated, roped-off sandy swimming beach staffed by City of Sammamish lifeguards during summer (per official schedule, June 21-Sept 2, 2026, daily 12pm-7pm). Free loaner lifejackets are provided for children/weaker swimmers. King County monitors the beach weekly for bacteria in swim season and rates it as having historically good water quality. The lake also supports fishing (stocked trout, bass, perch) and non-motorized boating from an adjacent launch/dock.

📍How to get to this swimming hole

Pine Lake Park is at 2401 228th Ave SE, Sammamish, WA 98075, on the lake's eastern shore; the swim beach and parking are accessed directly from the park entrance off 228th Ave SE.

Parking: Free on-site parking lot with gates operating 8am to 30 minutes after sunset; reviewers report the lot is small and fills quickly on sunny summer weekends, with parking described as tight or 'almost impossible' at peak times.

🥾The walk in

No real hike here. The water is a short walk from where you park. No hike needed. This is a drive-up neighborhood park on the lake's eastern shore; the on-site parking lot sits within the park grounds adjacent to the swim beach and other amenities (picnic shelters, play structures, boat launch). No source specified an exact lot-to-beach walk time, but layout indicates a short walk of a few minutes at most.

💬What regulars say

Locals echo official guidance that the free parking lot 'gets crowded on sunny weekends and during events,' and recommend early arrival, consistent with this being a popular local suburban lake beach rather than a remote or quiet spot.

📜Backstory

The park property was a private resort (French's LaPine Resort) from the 1910s/1930s until King County acquired it as a public park in the mid-1960s; ownership passed to the newly incorporated City of Sammamish in 1999, with a park renovation completed in 2004.
