For years our big annual vacation has been a weeklong wilderness backpacking trip, and I have to say it is rather badass from a mustachian perspective.
While you can spend a chunk of change on gear, you don't need to, and once you have the basics, you are set for many years to come...plus...
- You don't want to be carrying a lot of food, and most trail food can be very inexpensive so you don't spend much on supplies
- Once you buy food, cooking fuel, some replentishing of batteries, sunscreen, and such...along with gas driving to a trailhead YOU CAN'T SPEND MONEY FOR A WHOLE WEEK. NONE!
- On top of that, you get lots of exercise (my wife and I each lost 10+ pounds on one of our trips, and we're not that big to begin with)
- And most valuable of all to us, we completely unplug, decompress, see gorgeous land, and have an exquisite time.
We have some more swanky stache vacations (mostly based on free lodging in really cool places through family and friends), but I still think this one is tops!
