This might be my favorite MN State Park. There are hiking/skiing/horseback trails, I particularly like Landmark Trail with it's wonderful views of interesting terrain and Ogechie Lake. The archeological/anthropological information is fascinating, and I'm glad there are some perspectives shared of Native people today.
All in all this seems to me like a well managed state park for a day of adventure or a calm picnic. The observation tower is fun even though I can't get very far up it! I can't speak for the camping as I haven't been there yet (but want to).
