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

Uncas Sand Dunes SNA August 29, 2020 |
About
Aug 29, 2020 Today's adventure was back to Uncas Sand Dunes, a Minnesota Scientific and Natural Area. You may need to turn your volume up to hear the birds! Uncas Sand Dunes is an amazing place. It's far enough out of the city that there isn't a ton of city noise...although there were airplanes that flew over. The area has some hiking trails and a beach, but the inner road is a bit rugged. it doesn't really have potholes, but it has big ruts and angles where the road sort of falls off. |
