I’ve done Yam li’Yam… which is overlaps a lot (in the North)
things to bring:
sunscreen
changes of underwear and socks
things to snack on while you hike
raingear (I went pesach time two years ago… really good story if you’re interested)
stuff to start a fire and heat up water
Goldbond/babywipes
sandals
FLASHLIGHT (and flares if you want to be extra safe… all part of that story)
ace bandages/wraps
You don’t need a tent (if you’re a tiny bit adventurous- I didnt have one)
if i think of anything else I’ll let you know
