Cress Creek Nature Trail

Cress Creek is a pretty easy hike.  It is paved most of the way and has an outhouse at the beginning of the trail. This hike is family friendly and has lots of places to take breaks along the way.  https://www.alltrails.com/trail/us/idaho/cress-creek-trail

Yellowstone National Park

This is pretty self explanatory:) There are many hikes and stops along both the lower and upper loops. The cost is $35 per car entering the park. Website
