If you love to explore Skyrim you'll probably want to try the Master the Summit mod for Xbox One and PlayStation 4.
Master the Summit installs paths that allow you to easily traverse some of the steeper/rockier locations around Skyrim. To reach some of these locations in the vanilla version of the game you need to spam-jump. If you've done it, you know it can be tedious.
We haven't encountered every path but the few we have seen look great and don't take away from Skyrim's immersive experience.
If you want to explore off the grid, you'll want to try this mod out today. It's a good one.
