Otter Tail Beach Resort – Stayed there this spring for the first time and would definitely go back. Resort owners live on site and were more than helpful with anything we needed. Most cabins do not face the lake, but are updated and very clean with everything you need plus some perks (TV, AC & Heat) . South east side of the lake just south of gas stations etc in Otter tail.
If its a family trip or have kids they do have a very nice sandy beach.
