We're planning on travelling to the USA (again) following a successful 4 week National Parks RV tour (from San Francisco to Denver) in 2008. Prior to the trip, last time, we sought advise from your website and found the information on the forums, and the responses to our posts most invaluable! So thank you, and this brings us back here again hoping to get new insights for our next trip. This time we'd like to do an RV trip from Salt Lake City to Seattle (or vice versa) with a similar sort of travel time as our first trip, 4 weeks.
The key NPs we'd like to visit are Grand Tetons, Yellowstone, Glacier, Mt Rainier and Olympic although we are flexible if it means a more efficient route or get see more interesting things along the way.
Our initial questions are:
(1) When is the best time to do this trip? At the moment we are planning on mid Sept-mid Oct.
(2) Which direction should we travel (SLC->Seattle or Seattle->SLC)? I guess this may be dependent on the time we're travelling as well. Ideally we'd like to maximise best weather for walking in all the Parks but if we had to prioritise then it would be Yellowstone first and foremost!
(3) We think 4 weeks would be enough for most if not all these parks but please correct us if we're wrong.
Thanks in advance,
2Ts (from Sydney, Australia)
