In reply to Edvenables:
As an idea of cost, this summer I did a 2 month US road trip. California, through the desert, vegas, grand canyon, page,, zion, moab, yellowstone then back down to san diego and LA. Rented a campervan. Stayed mostly in campsites. Trip cost £12000 For 2 people!!
We were ppanning on camping the whole way round but we just couldn't stomach the heat at night in the desert, 39 degrees celcius at 11pm while trying to sleep in the back of a campervan thats been cooking all day...horrendous. if you go to the desert just get an air conditioned hotel and save yourself the bother. Get up and 5am, do your thing then retreat to the room at midday. In the cooler places like yellowstone its much more bareable, but still the same as top end britain in the summer.
-whenever you see a price it doesnt include tax...go into a "dollar store" and itll cost qbout about $1.10 for anything....its the same on everything everywhere!
-be prepared the horse and deer flys.
My top advice is go for it....its a great country and the people are so friendly (though they dont say thanks when you wait for them to pass on a trail...I guess its cultural differences). Dont underestimate the cost, however I'm sure you coupd do it cheaper than us...we spent quite a while in vegas and san diego and did white water rafting. That being said, for 3 months I reckon about £6000 each minimum. Car/RV rental will be by far your biggest cost.
If you want any more advice feel free to pm me
If you go to yosemite its lovely and cool at night, though tuoloumne meadows is actually cold enough for down jackets at night, even in the summer!!
We planned on climbing...but was just far to hot so didnt do any. However, if you go to the desert there is canyoneering which is incredible and worth doing as theres nothing like it in Europe. In fact the desert in general is spectacular...the grand canyon is nice, but iinda what you expect it to be, head to page and check out upper antelope canyon and horseshoe bend, go to the coral pink sand dunes and then zion national park. Zion is the best for canyoneering but moab is pretty good as well.
We kinda went with the idea of doing lots of climbing...in the end we did none, but did do canyoneering, white water rafting, mountainbiking in moab and a host of spectacular hikes. We are glad we did...while I am sure the climbing is great, abseiling into a 2 foot wide slot canyon with shafts of light from above and not another soul around is amazing wnd unlike anythink in this country!!! I highly recommend it.
Some tips;
-everyone says it, but the distances are VAST
- you will need full collision damage waiver and supplimentary liability insurance on top of your base rental price. A lot of rental companies only add this price on at the end. You also have to pay sales tax not included in the headline price. For example, the 'price quoted' for our rental was $4300 for 2 months..the final price was $6000. Dont take the risk...get the insurance
