When we do an Intro to Backpacking weekend as part of our Spring hiking program, we tend to go in a relatively short distance to a lake/pond or something along those lines. And then will do one or two day hikes from there. This gives plenty of time to experiment with gear, setting up/breaking down camp, and so forth without the time pressure of having to get to some destination. (But you still get a sense of pack weight and so forth.)
