Washington County doesn’t have a ton of information on their website about their regional parks, but they have this park’s brochure which covers it much better.

NOTE: You’ll need a Washington County vehicle permit for the regional parks (which is also good for Anoka County regional parks). And you’ll need a Minnesota State Park vehicle permit for the state parks.

Afton State Park (Hastings)

In the southeast corner of Washington County is Afton State Park with 20 miles of natural-surface hiking trails. 6 miles of those are maintained during the winter months.

Afton has a hike-in campground that’s directly connected to the trail system. This is a great way to try backpacking or to introduce it to younger children before heading into more remote destinations.

There’s a wide variety of terrain including next to the river, open prairie and dense, mature forest. Some of the hills rival the mountains for steepness! The park is very popular with trail runners.

Here is Afton’s summer trail map and the winter trail map.
