This summer myhusband and I are planning for our one year anniversary to fly from Knoxville, TN and spend a week exploring the Grand Tetons and Yellowstone. I know they are huge so we were wondering what we be best to do with the week we have. We actually were hoping to fly close to yellowstone and find a bus that would drop off at an entrance to the park then hike the entire trip until time to fly home lol. But from everything I've seen online this is not possible. We are 22 and 23 yrs old. We don't mind roughing it and are very active. We are on a tight budget also. We want to fill an ice chest with food when we get their and camp in a tent at the sites available. Besides the internet research I've done we are not familiar with the area. IF I HAVE to rent a car (lol) we would like to go ahead and fly into Jackson Hole and stay a couple days in the Tetons then on to Yellowstone. Any advice on cheap rentals or best campsites to stay at or even hiking trails as we prefer to do this mostly? Anyone ever hiked in the Tetons as well? Trying to plan an adventurous cost effecient trip. Thank you in advance!!
