Backcountry backpacking is considered a type 2 fun.
Backpacking requires a few things to be successful. For example you might want to rent or buy a tent, sleeping bag, sleeping pad, backpacking backpack, trekking poles, a water filtration system. Additionally you will want to bring dehyrated food, snacks, a map, and a compass. Additionally, it is always best practice to inform friends and family of your trip and when to expect you home so that they can be prepared in the event you do not return.
