Twin Falls (Olallie State Park)


Day Hike - Twin Falls (Olallie State Park)

Hike in a leisurely way along the Snoqualmie River and up to the falls, stopping to admire (and maybe learn to identify) some of the common mosses and lichens. We'll see if there are already signs of spring.

Twin Falls Trailhead, 8:45 am. Ready to move out by 9 am...and there is only one restroom at this popular trailhead.

Discover Pass required

The Twin Falls hike has an amazing variety of lowland forest vegetation as well as the often spectacular falls. This IS a Naturalist hike, so be prepared for frequent stops and discussions rather than aerobic conditioning. Bring a loupe if you'd like, to see some of the fine details of the mosses and lichens.  Ever wanted to see the pencil script or barnacle lichen or the hanging millipede liverwort? 

Group size will be limited, with two leaders, so we can keep our distance. Trip goes rain or shine: the falls are more dramatic in rain, and the plants love it.

Expect an email with any updates a couple days before the trip.
