Maine to Yellowstone

How long do you have to make the trip -- 3 to 6 months????

One can see the main points of YS in 2 days, or you can spend a life time seeing YS. I suggest you look at the route that the guide bus tours take to see the south west in a week or so to help you plan your time..

1. A day or a 1/2 day drive through the Badlands of SD

2. A week to see the 5 national parks in SW Utah.

3. A day to see Grand Teton NP

You need to make reservations soon!!!!!

It basically depends on your available time, as TenOC said 2 days (you won't see much) or a lifetime, first trip to Yellowstone, we spent 9 days there, second trip spent 14 days, could've spent more, it all depends on personal choice.
Also timing is important, spring back here in the east, (even in Maine) is generally April, Yellowstone, may still have snow in some places late May-early June.
