Been there, doing that...
You're a few months behind me then, I finished my PPL 2 months ago...
A few days after the test I did a dual flight with my instructor to cover / improve on the minor points the examiner remarked on, then a a solo local nav while waiting for the licence to come back from the CAA.
Since it has come back I've flown with my son on a local flight, then landed away at new destinations with friends, so I can gain experience from them, and the planning / nav through unfamilier areas.
I'm keen to keep learning so trying to go somewhere new every flight at the moment! I'll probably start the IMC course in a few months.
My club arrange fly-outs regulally over the summer so i'm planning to go on most for the experience.
