You definitely shouldn't forget about the bug spray and all the basic stuff for camping. But also, many people forget about the sources of electricity, so get something like Solar generators to always be able to charge something or power it even in the wild, and because of the solar panels, you won't have to worry about the energy.
As for me, if you want to go on a short trip, then you should definitely take a small tent with you, because in this way you can relax or spend the night in the open. It's very romantic and exciting! I can recommend this camping tent and supplies to you
With these things, you can have a great mini-trip.
