I am starting to plan a grand circle tour most likely in mid-August 2012. We are planning to fly directly from London to Las Vegas. We have around 2 1/2 weeks, as the last five days or so of this trip we will be staying in Vegas to visit family. We are very active and outdoor-loving people and will give anything a try at least once.
At this point I am very open to suggestions of places to visit that previous vistors enjoyed the most in this area. It would also be great to find out how long to stay in each area and if it is really feasible to have one base to visit several parks (Bryce, Zion etc..) or if it is not worth the hassle driving back and forth.
One thing I am set on at this point is to hike the Narrows at Zion (2 day version perhaps) but any other hike suggestions are welcome. We are also contemplating heading up to the Rockies National Park as well for 4 days or so if this is feasible. We don't mind a busy itinerary, so let it rip!!! Thank you very much!!!
