All winter activities do cost $5 per person but is 100% worth it! All of the trails are clearly marked and have check points along the way, if tracing in the winter months there is a small historical town you can walk through and see the inside of the building. Have a plan before you go and check in at the visitors center they are very knowledgeable and can help make the trip even easier!

There are several trails in this area, and one could easily spend an entire day covering all (or at least most) of them. OK for hiking, good for easy mountain biking, and great for cross country skiing in the winter. Watch for sand cranes, swans, and moose.

Lots of parking with restrooms and water. Great trails, friendly people. Easy trails around the lake. No rocks.
Great for novice horse and rider. Back Trail to the top of the hill is worth the ride for the view.

We love Harriman. We've taken the family mountain biking here twice in the last several weeks. It's important to note that the location for this set of trails is not correct. First of all Harriman State Park is located about 15 minutes north of Ashton, ID; not St. Anthony.

There are lots of trails around this park. Most of the trails are single track trails. However, since we have a double bike trailer for hauling 2 kids we have stayed on the 4x4 trails and had plenty of fun. We recommend parking at the second parking lot near the horseback riding staging area. Then ride the trail northeast through the cabins. At the cabins you can turn right and follow the river around to the dam/pond, or you can go through the livestock gates and cut across the meadow to the dam/pond. The grass is really tall in some areas going around by the river, so cutting across the meadow is much faster/easier.

The trails were easy enough for my 7 year old to hang tough for nearly 10 miles on his BMX bike with one gear. Bring a lunch or a stove to cook dinner in the late afternoon. It's very quiet and peaceful here.
