I used to walk along established trails in my local state parks that would take about 2 hours to finish. Nothing wrong with that. It's a nice way to stay fit.
Depending on which park I was going to, it could be anywhere from 5 miles away to about 20 miles away. But I never had to fight over parking spots, all my local parks had ample parking, and they were never really crowded.
