Alder Lake is the nearest full-size lake to Ashford WA — just 15 miles (about 20 minutes) via WA-706 west through Elbe. This 3,028-acre reservoir on the Nisqually River is the best option near Mount Rainier for motorized boating, water skiing, swimming, and lakeside camping, with a public boat ramp and campground managed by Pierce County Parks. Fishing for rainbow trout, kokanee salmon, and bass is productive from May through October. Peak season for all activities is July and August, when water temperatures reach 65–70°F.

How to Get to Alder Lake from Ashford
From Ashford, drive west on WA-706 for approximately 10 miles through Elbe. At Elbe, turn right (north) onto WA-7. After about 4 miles, turn left onto Alder Lake Road to reach the park entrance and boat ramp. The total drive is around 15 miles and takes 20 minutes under normal conditions.
From Seattle, take I-5 south to WA-7 south through Spanaway and Eatonville. Alder Lake is on WA-7 south of Eatonville — about 65 miles and 1 hour 15 minutes from downtown Seattle without stops. This is the same highway that connects Seattle to the Elbe / Ashford / Mount Rainier corridor.
Fishing at Alder Lake
Alder Lake is one of the more productive fishing lakes in Pierce County, with a combination of stocked and naturally reproducing species. The large basin (over 3,000 acres) supports boat trolling as the primary technique for trout and kokanee salmon, though shore fishing from the day-use area and boat ramp dock is also productive for bass and perch.
What You Can Catch
| Species | Best Season | Best Method | Notes |
|---|---|---|---|
| Rainbow trout | Apr – Jun, Sep – Oct | Trolling, bait fishing | Stocked by WDFW; most abundant species |
| Kokanee salmon | Jun – Sep | Trolling (small spinners) | Land-locked sockeye; check WDFW for open seasons |
| Largemouth bass | May – Aug | Casting near structure | East-end coves and submerged timber hold bass |
| Yellow perch | Year-round | Small jigs, bait | Good from shore or dock |
| Channel catfish | Jun – Aug | Bottom fishing at night | Night crawlers or cut bait; shallower west end |
Fishing license: A valid Washington State fishing license is required for anyone age 15 and older. Purchase at WDFW.wa.gov or at local sporting goods stores in Eatonville or Puyallup. Confirm current bag limits and species-specific regulations at WDFW before your trip, as kokanee seasons and quotas change annually.
Best spots: Trollers work the main channel from the boat ramp northeast toward the dam. Bass anglers find structure in the coves along the east and south shorelines where submerged timber from the original riverbed provides cover. Shore anglers at the day-use area catch perch and occasional trout from the dock and gravel beach.
Boating and Water Skiing
Alder Lake is one of the few large lakes near Mount Rainier where motorized boats and water skiing are fully permitted. The lake is large enough (nearly 5 square miles) to support water skiing, wakeboarding, and tubing without constant congestion, though summer weekends can be busy on the main basin.
The public boat ramp at Alder Lake Park provides concrete lane access to the water. Boats up to any size can launch here — the ramp handles everything from kayaks to ski boats. There is a day-use parking area adjacent to the ramp. Arrive early on summer weekends; the ramp and parking lot fill by late morning from late June through August.
Personal watercraft (jet skis) are allowed on Alder Lake. All Washington State boating laws apply — life jackets for children under 13, registration for motorized boats, and sober operation. Tacoma Power owns the dam and reservoir, but public recreational use is permitted through the Pierce County Parks agreement.
Kayaking and Paddleboarding
Non-motorized paddling is excellent in the coves along the east shoreline, which offer calmer water away from the main channel where ski boats run. The forested banks and occasional heron sightings make a morning paddle on the east coves a peaceful alternative to the busier main basin.
There are no kayak or paddleboard rentals at Alder Lake — bring your own or an inflatable kayak. Inflatables work well here and are easy to transport from your Ashford cabin. The boat ramp can be shared with motorized traffic; launch in the morning before powerboats arrive for the least congestion.
If you're looking for non-motorized-only paddling, see our complete kayaking guide which covers Mowich Lake (non-motorized only, inside the park) and Packwood Lake (hike-in, no motors).
Swimming at Alder Lake
The day-use area at Alder Lake Park has a designated swimming beach with gradual entry and gravel/sand bottom. Water temperatures vary significantly by season:
| Month | Approx. Water Temp | Swimming Conditions |
|---|---|---|
| May – June | 52–60°F | Cold — wetsuits recommended |
| July | 63–68°F | Good — comfortable for most swimmers |
| August ★ | 67–72°F | Best — warmest water of the year |
| September | 60–65°F | Good – cooling; quieter crowds |
| October – April | 45–55°F | Too cold for comfortable swimming |
There is no lifeguard on duty at Alder Lake Park. Children should be supervised at all times. The swimming area is not roped off from the boat launch, so be aware of boat traffic — stay in the designated beach area. Early morning weekdays in August offer the warmest water with the fewest boats.
Camping at Alder Lake
Alder Lake Park (Pierce County Parks) has a developed campground with both tent-only and utility hookup sites for RVs. The campground is set among second-growth Douglas fir at the east end of the lake, within walking distance of the boat ramp and swimming area.
Facilities include: Vault and flush toilets (depending on site area), drinking water, picnic tables and fire rings at each site, and a camp host on site during peak season. There is no dump station on site — the nearest is in Eatonville.
Reservations: Strongly recommended from Memorial Day weekend through Labor Day. Book through Pierce County Parks reservation system. Walk-in sites are occasionally available midweek, but the campground regularly fills on summer weekends by Thursday online reservations.
Using Alder Lake as a base: At 15 miles from Ashford and 35 miles from the Nisqually entrance to Mount Rainier National Park, the Alder Lake campground works as a budget-friendly base for multi-day Rainier trips. Drive 35 minutes to Paradise or 1.5 hours to Sunrise from camp.
For a more comfortable base with fast WiFi and a proper workspace, Refresh House in Ashford puts you 5 miles closer to the park entrance — and 15 minutes from Alder Lake for afternoon paddles or evening fishing.
Alder Lake vs. Other Lakes Near Mount Rainier
| Lake | Distance from Ashford | Size | Motorized | Camping | Best For |
|---|---|---|---|---|---|
| Alder Lake ★ | 15 mi / 20 min | 3,028 acres | Yes | Yes (Pierce Co.) | Boating, fishing, swimming |
| Lake Kapowsin | 30 mi / 45 min | 480 acres | Yes | No | Early season fishing |
| Mowich Lake (NP) | 40 mi / 1.5 hrs | ~160 acres | No | Walk-in only | Quiet paddling, scenery |
| Riffe Lake | 50 mi / 1 hr | 10,600 acres | Yes | Yes (State Parks) | Large-scale boating |
| Packwood Lake | 35 mi + 4.4 mi hike | ~100 acres | No | Backcountry only | Remote wilderness paddle |
Alder Lake wins on convenience for Ashford visitors — it's the only large motorized lake within 20 minutes, and the only one with a public campground and swim beach this close to the Nisqually entrance. Riffe Lake near Morton is larger and better for all-day powerboating, but adds 35 minutes each way.

From Refresh House to Alder Lake
Staying at Refresh House in Ashford? Alder Lake is a 20-minute drive — the closest place to cool off on a warm Mount Rainier day without driving into the park. A typical afternoon loop: morning hike at Paradise or the Grove of the Patriarchs (easy, 1.5 miles), then drive 30 minutes to Alder Lake for an afternoon swim or paddle, back to Ashford for sunset.
September is particularly good for this combination: the park is uncrowded, Alder Lake fishing is at its best (trout and kokanee), and water temperatures are still comfortable for a swim or kayak.
