Hello. I am new to the forum and already it has been a help. I am travelling from San Francisco to Las Vegas in late March. I have a rental car and pick up the car on Saturday morning and need to have it in Vegas in the evening on Tuesday. So I have 4 days of driving. I want to see some parks before going to Las Vegas. I dont mind skipping Yosemite, but would like to see Sequoia. I also wanted to see Grand Canyon, Bryce, Zion and others if it is reasonable. Does anyone have any suggestions regarding the best routes and which parks would be best to see (and reasonable to fit into my trip). Also, can you drive through the Navajo Res.? Would that be a good way to go? I will end it here for now. Thanks in advance.
