We're travelling from Australia to Los Angeles in April 2014 and would like to do a 8 to 10 day tour of the West Coast taking in the Grand Canyon ,Las Vegas ,Yosemite and perhaps a few more of the other canyons perhaps ending up in San Francisco can people give us some suggestions of the best tours and companies to deal with. We're both in our early 50s but still young at heart. We would have no problems camping. We don't want to feel rushed and would be keen to involve some hiking. I imagine the cost of such tour would be around about the $1500 per head cost, just to give some idea. Any suggestions most welcome.
