We often take our dog here on the weekends for longer, out of city limits walks. The trails are the perfect amount for that purpose and he enjoys the wildlife that hides in the natural prairie fauna. The trails hug the river so there's easy enough access if you wanted to play in the water. You do have to walk through some brush however, so be aware.
The swimming area is wonderful! Less chlorine than you'd ever get exposed to in a public pool and picnic table access with lots of area to picnic.
We have not camped in this park yet.
All campsites are hike-in, with the closest being about a mile in. Pack light. This was my first solo backpacking camping trip (also first with a 6 month old GSP) and the pack in was fine but hiking out I definitely learned that I over packed.
I stayed at Campsite #8 which was beautiful, serene and right next to the Manitou river, so easy access for water filtering and for the dog to drink. There is a very nice fire pit with grill rack, although no bear pole and not very many tress that you can get your food up in easily. There are two perfect trees to hang a hammock right near the tent flat area.
We didn't see much for wildlife, except for a few birds, although there was some wolf poop in our site.
Overall a great place for a solo hiking trip. There weren't as many views of lake superior as I thought there might be. Although, I would like to go back and continue to follow the river all the way to the shore, or at least see if that's possible.
