The Annette Lake Trail #1019 begins quite mildly, not too rocky or rough, and is fairly well maintained. Youll quickly cross over Humpback Creek and shortly thereafter break out into forest cleared for the high tension power lines overhead. A few hundred feet before the power lines, see if you can find the 8 wide abandoned culvert skulking off the trail. Presumably a portion of Humpback Creek was once funneled through this monster. Makes a fun little stop and provides a much needed roof in the rain.
Beyond the power lines the well-marked path intersects with the Iron Horse Trail and begins a mild ascent up towards the lake. Both switchbacks and inclines increase as you press onward, ratcheting up the challenge after lulling you for the first two miles. The trail cuts through more than a few talus fields afforded some interesting views of the Humpback Mountains craggy outcroppings and colorful rock faces.
The forest is a pleasant mix of firs and pine, old enough to have long since replaced brushy undergrowth a carpet of moss. The last half-mile or so of the trail levels out and you soon find yourself at the lakeside, at the bottom of a bowl formed by the surrounding Humpback Mountain, Abiel Peak and Silver Peak. There are small picnic and camp sites on the trail around the edge of the lake, as well as some rough amenities for an overnight stay. For those looking for more of a challenge, rough trails lead up from the lake to Humpback and Silver Peak.
Surrounded by mature forest and nestled beneath intriguing heights, it is easy to see what brings the crowds to Annette Lake. Moreover, the trail is well-maintained trail and not too strenuous, making it approachable for a wide range of hikers of all ages. At the same time Annette Lake is certainly not the most stunning alpine lake in the area. If you prefer a little more quiet and solitude, we recommend skipping Annette Lake during the summer months.
Annette Lake has been a favorite of Seattle hikers for over a century. Named in honor Annette Wiesling, a prominent member of The Mountaineers near the turn of the 20th century, today the lake welcomes hundreds of hikers every summer.
