We were in a caravan of 5 jeeps. Already stated - newer, automatic jeeps w/ AC. No off-roading. This is a 120 mile tour on a flat road where you'll see lakes, rivers, streams and possibly Denali (on a clear day). We got several beautiful family shots that will look great on our Holiday card. We saw 1 moose and that was really it. Oh, swans on the lake. At 60 miles in, we turned around and headed back on the same road. It was enjoyable for the first 30 minutes or so, but this is an almost 5-hour tour. We had 2 kids w/ us and they were completely bored. I wouldn't recommend this for families - as mentioned in previous reviews, whiney kids aren't fun for anyone.
Pros - the guide was fantastic - extremely knowledgable. They offerred snacks and drinks at the halfway point, nice touch. There is 1 bathroom stop. Jeeps are very nice.
Cons - gets repetitive and long, especially because you turn around and come back the exact same path. Not recommended w/ kids.
