Since one is going to return the next day, yes there are a few morning hours when a person will be rested though will be forced to get on the route back early if it is long. So what threshold makes that worthwhile?
A good example of that is Pioneer Basin at 11 miles and 2700 feet vertical going in. Unlike many destinations where it is up the first day and all down on the return, because of the crest one has to climb all the way back up 2k going out. So yeah possible for not much more than a peak bagger's endurance challenge.
Thus for overnight trips which means 2 days, one going in and one coming back out, key requirements are:
- Not having to drive so far from wherever one lives else possible hours on the road versus on the destination have little balance over just 2 days. For this person that is 4 or 5 hours max.
Any national park destinations or the still few national forest destinations that demand standing in front of a person for a sermon at a ranger station at 8am or later Saturday mornings on trail departure days make getting enough hours in at destinations for activities rather hopeless. Conversely being able to get a short notice wilderness permit at recreation.gov then having it set up for a night box pickup on the evening of a drive in is ideal. And that can leverage a night hike in too in order to really have a day.
Mileage and time on the trail is short so after one gets to wherever, they are still lively and have enough time to enjoy themselves both on the hike in day and the next morning. This requirement eliminates a lot of backpacking destinations that are long one day efforts. Of course the more ultra-light the more strongly conditioned a person is, the further that can be.
