My biggest suggestion would be to get out in nature. Unless you are really opposed to spending a decently long time without creature comforts then I think this is one of the best things. Another piece of advice is to stay away from crowds like you pointed out. There is a seemingly infinite amount of destinations that could satisfy this requirement too. Best of luck! I hope you find something suited to you and feel refreshed after getting back.
