After two days visiting Denali park we decide to do something a little different...My wife and I wanted to something to pump a little adrenaline, so we took and ATV tour. Wow, we had a blast. My wife, 65, had her hip replaced a year ago and her knee replaced 3 months ago, jump on the ATV and left me literally in the dust. Denali ATV Tours did a wonderful job with the tour and care for her safety. Our Leader was 19 year old Doug was an absolute pro as were JD and Jeremy. One suggestion to anyone reading this post...take the 3.5 hour tour...if you don't, you will wish you had.
