Hi I will be visiting Yosemite around 19/20th April this year. We will be coming up the long way around from Death Valley as I know that Tioga Pass and various parts of the park will be closed due to snow. However will we will be able to get to Mariposa Grove and will all Yosemite Valley be accessible? I'm trying to get an idea or whether to spend 1 or 2 full days in the park at this time of year?
We then plan to drive to San Francisco on hwy 120 - are we likely to encounter any snow problems on this road?
