Whether you've got the time/inclination/skill for a remote camping trip that requires packing everything in via a day-long hike ... or you just want to meander around a local park for an hour, more and more science is in agreement: nature is good for what ails you.
The BWCAW has been allowing overnight camping since May 18. Permits and resources for planning trips are available online. The Department of Natural Resources began a phased reopening of Minnesota state campgrounds on June 1 (some feature hike-in and paddle-in sites). Dispersed and backcountry camping is an option at Minnesota state forests and in the Superior National Forest.
The State of Minnesota has issued some guidance for the public on safe outdoor recreation practices during COVID-19 (see page 5-8). Campers are asked to buy permits online, maintain social distance, and limit in-person interactions by purchasing needed supplies close to home. Wearing a mask when stopping for gas and supplies is recommended. Campers should be prepared with hygiene products like soap and hand sanitizer to help prevent the spread of COVID-19.
