Comments

This SNA is in the Sand Dunes State Forest.

Getting There
To locate this SNA follow the directions on the Minnesota DNR Web page to get to the Ann Lake Campground and Day Use Area. Drive through the campground until you get to the parking area for the SNA just past campsite #28.

Hiking Trails
A hiking trail follows the northern boundary of the SNA. Another trail follows about half of the southern boundary. The North Orock Trail, a horse/hiking trail, passes through the SNA and connects the SNA boundary trails. All of the trails are former forest roads.

Deer Flies
Deer flies can be bothersome here in June and July. Bring a mosquito headnet and do not leave it in the car. At some point you will want to use it.

Poison Ivy
This site is memorable for, among other things, an overabundance of poison ivy. Long pants are strongly recommended, even for the trails.
