We are thinking of renting an RV and visiting the Rocky Mountains (like Colorado, Wyoming, Montana) for the month of July. But having never been there, we have no idea how to even begin our itinerary! We'd love to see some National Parks but are fairly limited in terms of hiking etc because we have a 3 year old, 7 and 11 year old--mainly the 3 year old that is the problem:) We thought of starting in Denver and then ending up maybe in Seattle or somewhere in Oregon to drop off the van. Any suggestions would be very welcome!!
