Yes, "glamping" has become a global trend for experiencing the great outdoors, yet this form of accommodations is by no way cheap, which means it will eat right through your budget.
Instead, pitch a tent and reconnect with nature the old-fashioned way by camping. Not only will this be the most authentic experience during your trip, but it will also save you tons of money. Some of the campgrounds we stayed at were less than $20 a night and had all the amenities we needed.
There are numerous inexpensive campsites around all the national and state parks, not to mention other reputable campgrounds such as KOA and Camp in my Garden. You can even find free camping sites on freecampsites.net. Talk about a sweet deal!
If camping isn't your cup of tea, that's fine, too. You can find cheap accommodations through Airbnb, VRBO, and of course, taking part in the classic Couchsurfing movement.
