Reykjavík, Iceland
The jetlag can be pretty intense.
So, if the jetlag is really bad, you walk out to this place. It’s farther than you think, and you take off your shoes and put them in the hotsprings. Difficulty is low, but it’s pretty far with no hills. You be the only non-Icelandic person there, unless you’re Icelandic. There are also other bootleg hotsprings nearby, that’s where the cool people are.
