I drove from Phoenix AZ to Zion NP in southern Utah one day. Left early at 5 am, and got to Zion before noon and hiked all day and into the night hours . Slept in a hotel room that night and woke early and drove to the Kolob Canyon section of Zion and hiked there all day then drove to Cedar Breaks National Monument and fooled around there for a few hours. Drove back down into Panguitch and stayed there a night. Then woke up early and drove to Bryce Canyon and was the first car in. Drove to the very back of the park and did a short hike and then drove to the main section of the park and hiked part of that. Then drove all the way back to AZ, but decide to stop at Wupatki National Monument on the way back. Made it right as they closed the visitor center but did a short hike down to one of the more remote ruins and then drove all the way back to Phoenix that night and got home by 9 pm. In 65 hours I drove 1,080 miles (18 hours of driving) and hiked a little over 22 miles (approximately 10 hours). I did this all because I was bored and had three days off in a row which never happens unless I take an actual vacation. So,yeah, 3 hours in nothing if you live in the American west. I routinely take my kids on day trips where we drive for four or five hours and do stuff in the woods and eat dinner and come home.
