This is an easy to moderate one way trail in Willamette National Forest. This can be done as a day hike (~4 miles round trip) or a backpack.
Please note that permits are required for both day use ($1) and overnight ($6). These must be purchased ahead of time online at: https://www.recreation.gov/permits/4675311. Additionally, an America The Beautiful Pass or Northwest Forest Pass should be displayed for parking. Note that rangers do patrol this area and ask for permits.
This route takes you to the north edge of the lake, but there are paths around each side of the lake. There is not a true trail around the whole lake as the south end of the lake is very brushy and overgrown.
The trail around the west side of the lake leads to views of Mt. Jefferson. Three Fingered Jack can be viewed from the north end of the lake.
Remember the 10 Essentials (https://www.nps.gov/articles/10essentials.htm) and to Leave No Trace (https://lnt.org/why/7-principles/). Be aware that this area is very populated with mosquitos and other insects, so plan accordingly.
Start at the trailhead for Marion Lake and head into the forest. After 1.2 miles, the trail reaches Lake Ann. At the Junction with the Marion Lake Outlet Trail #3495, stay to the left until you reach the water. From this point, there are trails to the east and west sides of the lake. Take the same return trail.
This is a nice hike for children, but be aware that insects (including mosquitos) are very active in this area, so bring plenty of bug spray. If you choose to take the spur trail to Marion and Gatch Falls, children shouldn't go as it's very steep, slippery, and dangerous.
