Easy to moderate hiking trails with lots of areas for rock climbing. It has two moderate trails connected to this trail that leads to the Interstate State park camp ground. Great views of the St. Croix river from many high elevations and overlooks as well as some areas close to the water level.

Rocky and sometimes challenging to navigate with lots of elevation changes. Tons of animals and scenic views. We explored all of the trails south of highway 8 on the Wisconsin side of the park. Great combination of terrain and there’s also a small waterfall as well. A few trees down on the paths but still able to get through.

Good trail — there are lots of rocks to climb and the potholes were frozen over but still impressive. Good river views too and not too crowded.

Beautiful little trail system around St. Croix, it’s getting warm enough to climb, and much of the ice is melting. So, be cautious getting around and crossing the river. As, there is much slick ice on the trails, and river ice is steadily melting. Solid day trip if you need to get away from the ruckus of the twin cities or the regularity your local town..

I'd give 3.5/5 for current conditions. The north parking lot is closed, so parked at the south entrance and hiked along the river trail to the glacial potholes loop. The river trail was the most enjoyable part of the hike, very peaceful, with views of the river most of the way. If you are going to see the Potholes I'd recommend waiting until spring or summer, it's all buried under snow right now, so not much to see there.

Nice easy path with river views at the end. Good during fall foliage.

The loop section has some nice rock formations and river views, the hike to the visitor center and back is not very scenic, some rock formations.

nice trail the potholes are really cool. it also has nice views of the river. the only reason I give it 4 stars is that it is right next to the road and you never get a secluded "away from it" feeling.

Really unique and beautiful - kids had a blast as well. The potholes are so much fun to see, and the scenic overlooks on the Saint Croix are breathtaking. Definitely will go back to do more exploring.

Wonderful trails! Horizon Rock and Meadow Valley (right across from Potholes) were our favorites.

Went to the park this fall. Great to have lunch on the cliffs. Is fun anytime off the year.

Lil ole St. Croix. I love this trail and have been on it my whole life. There is something for all ages here. Personally I like climbing just across the River in Taylors Falls. Over all I would definitely recommend a peak if you are in the area.

This is one of several trails within the Interstate Park in St Croix Falls, Wi. All of the trails combined might equal 8.9 miles but this one is less then 1 mile so don't feel as though you'll need to conquer all 9 miles. The views are exceptional, the trails are fairly rugged and well marked. There's no chance of getting lost here.

The trails here are well marked with not a lot of flat ground. Lots of rocks to climb, bluffs to look over, and expansive views of the river valley. This is a great day trip that I would recommend for just about anyone.
