Rollerblading can be an extremely fun date. Fast paced, you get a work out, and can enjoy nature around you. In Provo there two really good spots in my opinion. Provo river bottom trail, and Provo rock canyon park. The river bottoms are beautiful and flat so you can go at an easy pace. There are also tons of parks along the way you can stop at to take a break and get to know each other. With rock canyon park its a little more hilly but there are plenty of spots to stop and sit. The view is amazing. If done right you can watch the sun set together. Wink wink.
