Riverside Park is a carry-in access point and rest area located at river mile 144. 5 on the Otter Tail River in Frazee, near East Main Avenue bridge.

This location features a series of small rock weirs downstream that create faster-moving water, making it a popular take-out point for the recommended day trip from Wannigan Road (8. 4 river miles upstream).

The park provides a convenient rest stop with basic facilities for paddlers navigating this scenic section of the river.
