Snow Lake Trail | Snoqualmie, Washington Guide

The Snow Lake Trail in Washington's Alpine Lakes Wilderness is one of the best trails near Seattle and within the entire state. Starting from Snoqualmie's Alpental area, the trail winds its way through dense Douglas fir forests before reaching high alpine meadows and a gorgeous view of Snow Lake.

The Snow Lake Trail is most popular during the summer months, from June to September, when the snow has melted. Weekends tend to be busier, so if you prefer a quieter experience, consider hiking on weekdays or very early in the morning.

It is important to be prepared for changing weather conditions, as the area can experience sudden temperature drops and storms even during the summer.

Make sure to bring appropriate gear, including sturdy hiking boots, layers of clothing, sunscreen, insect repellent, and plenty of water and snacks.

Snow Lake is also very close to some other Pacific Northwest towns and cities, like Wenatchee, Leavenworth, and Ellensburg, that are worth checking out.

You'll pass another trailhead sign with a map before you start heading uphill. The path winds through the woods with some uphill sections and some flat sections. The view on the left gets better, and better the further you go.

The trail does get rockier as it progresses, though, so keep an eye on your feet and any young hikers with you.
