I intend to leave Las Vegas on october 3 returning to Vegas on october 27. We would like to visit Death Valley NP., Sequoia NP., Yosomite NP., Lake Tahoe, then we would like to go to San Francico stay there 3 or 4 nights and then travel from San Francisco to San Diego with multiple overnight stops in between. We would like to spend a few nights in Palm springs and visit Joshia Tree NP. before returning to Vegas october 27. I've read a tremendous road trip idea from Trip Advisor for our drive from Las Vegas to Yosomite including a stop in Death Valley but no suggestions on how to incorporate Sequoia within that trip. I thaught looking at the map that by lodging 2 nights in Lone Pine near Death Valley I could visit Sequoia the following day and then continue to Yosomite but to my surprise I was told there is no entrance for Sequoia near by and that I would be about 5 hours drive to that park. Any suggestions as to the best idea to how we could best add our visit to Sequoia NP. within that trip. We would appreciate any other suggestions for things to do or visit during that trip. I heard there is a yearly National Park pass that can be purchased. I wander if someone can tell me more about that. Thanks!
