Overview
Issaquah’s parks split into two worlds. On the north edge of town, Lake Sammamish State Park is the summer day-use destination — two swimming beaches, a boat launch, picnic meadows, and easy shoreline trails. South and west, the Issaquah Alps hold Cougar Mountain, Squak Mountain, and the Tradition Plateau on Tiger, with miles of forest trail starting minutes from downtown.
City parks fill in the gaps: Tibbetts Valley for sports fields, Memorial Park for a downtown playground, Confluence Park for a creek-side walk in town, and Grand Ridge for rolling singletrack on the east side. Pass rules change by land manager, so check whether you need a Discover Pass before you leave.
North Issaquah
Lake Sammamish State Park
Best For
About
Lake Sammamish State Park is the busiest and best day-use park in Issaquah on a warm summer day. Sunset Beach and Tibbetts Beach both have sand, grass, and roped swim areas, with seasonal concessions and paddleboard rentals. Flat trails loop the wetlands and creeks, soccer fields fill on weekends, and the boat launch is the only public ramp on the lake. Arrive early — the lots fill on hot weekends.
What to Know
- Discover Pass or a day-use fee is required to park
- Lots fill by late morning on hot summer weekends
- Sunset Beach is the main swim beach; Tibbetts is quieter with rentals
- The only public boat launch on Lake Sammamish
Issaquah Alps — west
Cougar Mountain Regional Wildland Park
Best For
About
Cougar Mountain Regional Wildland Park is King County land and the quiet counterpart to crowded Tiger Mountain. Trails fan out from Red Town, Sky Country, and the Wilderness Peak trailhead, passing mine shafts, the Red Town historic site, and creeks that run full in spring. It is free to park, close to town, and one of the best places near Seattle for a long walk in the woods without a summit grind.
What to Know
- King County park — no Discover Pass, free parking
- Red Town is the most popular trailhead; Wilderness Peak is closest to Issaquah
- Trails are muddy much of the year — waterproof shoes help
- Dogs allowed on leash
Issaquah Alps — south
Squak Mountain State Park
Best For
About
Squak Mountain sits between Cougar and Tiger and sees a fraction of the traffic. The May Valley trailhead is the main access, and the climb to the Bullitt Fireplace — the stone remains of a 1950s mountain estate — is the classic outing. Views are filtered rather than panoramic, but the forest is deep, the trails are well marked, and you can hike for hours without the Poo Poo Point crowds.
What to Know
- Discover Pass required at the May Valley trailhead
- The quietest of the three Issaquah Alps
- Bullitt Fireplace ruins sit near the summit
- Limited parking — a smaller lot than Tiger or Cougar
Tiger Mountain — High Point
Tradition Plateau
Best For
About
Tradition Plateau is the easy side of Tiger Mountain. From the High Point / West Tiger trailhead off Exit 20, mostly flat loops circle Tradition Lake on gravel and boardwalk, including an ADA stretch of the Around the Lake Trail. It is the best Issaquah Alps outing with young kids or anyone who wants forest and water without 2,000 feet of climbing. The same trailhead is also the start of West Tiger 3 if you want a harder day.
What to Know
- Washington DNR land — Discover Pass required
- High Point trailhead off I-90 Exit 20
- Around the Lake is the easiest loop; West Tiger 3 starts from the same lot
- The West Tiger lot fills early on summer weekends
Downtown Issaquah
Memorial Park
Best For
About
Memorial Park is the in-town play stop — a playground, picnic tables, and a ballfield behind City Hall, a short walk from Front Street and the historic depot. It is a practical picnic and play stop before or after downtown, and in October it sits on the edge of the Salmon Days crowds.
What to Know
- City of Issaquah park — free, no pass required
- Walkable from Front Street; parking at City Hall and along 2nd Ave
- The ballfield is often reserved for games on weekends
- A good rainy-day playground stop when the Alps are soaked
West Issaquah
Tibbetts Valley Park
Best For
About
Tibbetts Valley Park sits off Newport Way a few minutes from the state park, with baseball and softball fields, tennis courts, a basketball court, a playground, and a reservable picnic shelter. It is the city sports complex, not a wilderness park, and it pairs easily with a lake afternoon — play a game, then walk or drive over to Tibbetts Beach.
What to Know
- City of Issaquah park — free parking
- Picnic shelter and fields can be reserved through the city
- A short drive from Lake Sammamish State Park’s Tibbetts Beach
- Tennis, basketball, and a playground on site
East Issaquah / Highlands
Grand Ridge Park
Best For
About
Grand Ridge is the east-side wildland — rolling singletrack through second-growth forest, built as conservation land alongside the Issaquah Highlands. Access from High Point (Exit 20) or Central Park in the Highlands. The grades are gentler than Tiger, which makes it a good hike or ride for people who want miles without a steep summit, and it links toward Duthie Hill, one of the region’s best flow-trail bike parks.
What to Know
- King County park — free, no Discover Pass
- Access from High Point (I-90 Exit 20) or Central Park in the Highlands
- Open to hikers and mountain bikes; yield signs apply
- Connects toward Duthie Hill in Sammamish
Downtown Issaquah
Confluence Park
Best For
About
Confluence Park is the easiest nature walk in Issaquah — a short loop through lawn and trees along Issaquah Creek, a few blocks from Gilman Village. In the fall you can often see salmon in the creek without driving to the hatchery viewing area. It is not a destination park on its own, but it is the right stop if you are already downtown and want ten quiet minutes by the water.
What to Know
- Free city park at 655 Rainier Blvd N
- Short, easy loops — good with small kids
- Salmon are visible in the creek in late September and October
- Limited on-street and small-lot parking

Things to Know
Passes Change by Park
Tiger Mountain and Tradition Plateau (DNR) and Squak Mountain State Park need a Discover Pass. Lake Sammamish State Park takes a Discover Pass or a day-use fee. Cougar Mountain, Grand Ridge, and city parks are free.
Weekend Lots Fill Early
Lake Sammamish, the West Tiger / High Point lot, and Poo Poo Point fill by mid-morning on summer weekends. Arrive before 9am, go on a weekday, or choose Cougar or Squak for easier parking.
Two Kinds of Parks
The Alps parks are trail systems, not playground-and-beach city parks. If you want sand, swim buoys, and a picnic table, go to Lake Sammamish or a city park. If you want a forest hike, go to Cougar, Squak, Tradition Plateau, or Grand Ridge.
Dogs
Leashed dogs are welcome on most Issaquah Alps trails and in city parks. They are not allowed on the designated swimming beaches at Lake Sammamish State Park.
