Tips from the Community
Great views over Spada Lake, which provides most of the city of Everett's drinking water. Because of that no swimming or wading is allowed, and your pets must be on leash at all times. There can be good trout fishing here, though.

Two small, tranquil ponds just off the Greider Lakes Trail, but they are pretty socked in by greenery.

The trail into the canyon starts as a wide gravel road from the trailhead near the dam, and becomes a beautiful lush singletrack as the path turns off and descends into the canyon. The river at the bottom is wide and shallow.

Culmback Dam was created in 1965 via the Henry M. Jackson Hydroelectric Project. This hydroelectric dam on the Sultan River creates Spada Lake, which provides drinking water to nearby towns and serves as a recreation site.

Boulder Lake is a stunning alpine vista with a dramatic mountain backdrop. The Boulder Lake trail has recently needed maintenance β check to see if the trail is closed before you go. Reports say the DNR has begun to reclaim this trail.

There are restrooms near the lake, and the scenery here makes for an exceptional snack spot. Big Greider Lake is part of the Sultan Basin, which is Everett's public water supply β as such there is no swimming.

The trail is very steep and power-hikey up until this point, where it mostly levels out until you reach Big Greider Lake. Little Greider Lake is a great spot for camping, and the views are dramatic as the trail skirts between the two peaks. There is a camp along the lake.

Bear Creek Sites have overlooks that have benches and a view of the nearby forest and Lake Spada. The Lake is a drinking water reservoir, so swimming or wading is not allowed.
