Some of my friends are planning for a Canada trip on coming summer and they are having trouble for deciding how many days they should spend at the Yellowstone national park.
Although they made a contact with a touring agency as "USA Travel Online" for help but still it would be better if an experienced person could suggest a good Idea.
Welcome to Travelblog! Yellowstone is so large and varied that the ideal amount of time depends on your interests and stamina. What are you interested in seeing and doing? Many bloggers have written about the park, and their blogs will have plenty of suggestions. Personally, my last visit was three days and that was barely enough to see the highlights. Unless you are interested in a quick bus tour (which the Park Service offers, check the website) I'd try to plan at least a week.
Hello Lora and welcome to Travel blog. Yellowstone is an amazing place and the Tetons are close by so you will want to explore both.
As Ezra said you could get a glimpse in 3 days. If you want to do some hiking and really get a feel for the area I would recommend at least a week. There are enough trails to keep you busy for weeks if you are a hiker or skier.
If they are into hiking, I would suggest 5 - 7 days to do both Yellowstone and Tetons. There are a lot of walking trails in Yellowstone which will take you 3 - 4 days. And then it is worth spending couple of days hiking into Tetons. It is a huge park, so they might always consider changing lodging. When we were there, we first stayed (camped actually) inside the park, then we went out on the Teton side and stayed at a lodge, and then spent one night near Teton to get some hiking in.
