There are some tiny tin-box style games, often not very deep but maybe there is something out there worth traveling around with?
Railroad Ink is a roll-and-write game in a tiny box (or multiple tiny boxes of different colors) and scales well from just one to six players.
I recently travelled with the following small games and can recommend them.
Sprawlopolis - Lovely co-op city builder with 18 cards, much more replayable than you’d think.
Fugitive - A great cat and mouse/hidden movement game with numbered cards. Either flee as the fugitive or hunt as the marshal.
Air land and Sea - A tactical game with the added wrinkle of choosing when/if to withdraw.
Monopoly Deal - A classic, fast, fun, ruthless. Monopoly as it should be.
Hive Pocket - Chess like, strategic, tactile and can be played pretty much anywhere.
Stew - A simple bluffing card game of creating a stew together and working out when the best time is to eat the stew, if at all.
Hope this helps!

I haven’t seen “Wizard” mentioned yet. It’s a staple among german outdoor tourists.
