Welcome to the trip advice planning forums! May is a gorgeous time to be visiting the High Sierras and Yosemite. Dogwoods will still be blooming and the waterfalls will still be roaring -- assuming we get a decent snowpack again this year.

This year the road over Tioga Pass didn't open until May 18th (so it might be better to travel towards the end of May if you can). If the pass is still closed when you visit, you can still reach Mammoth Lakes and Lake Tahoe by using one of the other crossings -- most likely US-50.
