I am flying to Las Vegas on the 19th of December and returning back to London on the 31st from Los Angeles. I intend on staying in Vegas from the 19th-21st. I am going to hire a car. I want to go to the Grand Canyon and do a couple of hikes (perhaps also something on the river?-is this possible in December/ would it be too cold?). I was planning on driving from Las Vegas on the 22nd via Hoover Dam to the south rim of the grand canyon. I would probably stay there for 1 or 2 nights and then head for Lake Havasu (staying one night here) and then on to Palm Springs (1 night here). From Palm springs I was planning on going to San Diego (perhaps cross into Mexico- Tijuana). I would stay in San Diego for two nights and then on to Los Angeles (visit universal studios + hollywood etc etc).
I was wondering if people could give me an opinion on this road trip. Are there any ways I could improve it? Perhaps by picking a slightly different route? My main aim is to go on scenic routes and spend time in some cool/random/remote places. ( I guess lake havasu and palm springs don't fit this criteria!) I would really appreciate some ideas/thoughts/suggestions. Also, what would weather be like in December in these areas?
