Tons of great suggestions already shared, but I’d like to add one I haven’t seen yet.

Wilderness Survival / Bushcraft School

They exist in nearly every corner of the world. There will be tons to learn from instructors and other students alike, since that sort of program tends to attract other outdoor enthusiasts who may already have experience with basic camping and backpacking.

Many will offer overnight programs where you camp out in a safe environment while practicing skills that can save your life if things go really wrong, not to mention that they’re fundamentally rewarding.
