Ask HN: 'Restorative' trips for the fall?

I'm pretty burnt out. I'm looking for some trips that might help me get back to myself. I've tried to plan some larger trips but I don't have the energy, so I figure I should focus on something more restorative than anything else. Has anyone been in a similar situation? Where did you go / what did you do? I've got at least two weeks of PTO saved for Sept - Oct, for what it's worth.
