Lake Lowell is open year-round, from dawn to dusk. It is a beautiful lake, but in 2022 there were advisories due to a bloom to avoid drinking the water, eating fish from here, and swimming. Keep up-to-date with the water's health before taking a plunge.

This wide, gravel trail isn't the most difficult or technical of routes. However, it's great as an early season warm up hike or for breaking in new gear before tackling some of the area's more strenuous hikes.
