They’re all fun in their own way. Exploring long-abandoned forest service roads (particularly old dirt roads rather than gravel) is really fun, but ultimately pretty easy.

If you’re in a park and only a few miles from the trailhead they should absolutely have stairs and well marked, maintained trails. It prevents people from cutting switchbacks, stops erosion, and keeps the trails from being totally trashed from heavy foot traffic.
Go to a national park that has shelters with privies and compare it to a wilderness area where anything goes. The park will have well worn trails from millions of yearly visitors but the wilderness area will have dozens of superfluous fire rings and human shit and toilet paper in established campsites.
