Overall the Beaver's Den was a nice destination for a get-away. Even though there are many houses around the Den, it was generally very quiet. Very much enjoyed watching the woodpeckers, blue jays and hummingbirds enjoying the bird feeders. Would definitely stay here again if it's available when I'm in the area. Tried to kayak on the Chippewa River but gave up. The river moves deceptively fast and with no experience kayaking and traveling alone I decided trying to kayak would be a very bad idea.
For groceries there is a nice store in Evart and in Mt. Pleasant there is a Meijer's and Wal-Mart. Barryton does have a Dollar General but I don't know about the quality or variety of their food selection.
Do note that the air conditioning is window AC units and not central air. The window AC units are on the noisy side. There was also a number of moths and mosquitoes in the Den at times, most likely because the gap between the upper and lower window sashes with the AC units had not been blocked in some way. Also the floors weren't particularly clean. Ran the swiffer around the Den. It picked up a fair amount dirt and hair which I know wasn't my hair since my head is shaved, beard is very short and the hair was way longer than any hair that I have.
