Ira Spring Trail - Mason Lake
Snoqualmie Region
As of February 15, 2026, the Ira Spring Trail to Mason Lake is largely snow-free below 3500 feet, with sticky snow becoming more prevalent at higher elevations. Microspikes are recommended for boulder fields and near the lake, as snow can be slushy or firm. The primary access road (FR9030) is closed, requiring an alternate access via Exit 42 and Tinkham Road, adding about 0.6 miles and 500 feet of elevation gain. Be aware of some downed trees and potential mud on the connector trail. Mason Lake is reportedly starting to melt, with reports differing on whether it's frozen over or breaking up. Parking is available at Exit 42.
