You must visit Yosemite National Park it is great and so is going up to Pine Flat Dam and rafting down the river. Shaver Lake, now that is some of the coldest water I have ever seen that didn't have ice floating in it. Fresno is hot in the summer 104-110 which is normal. If you get a chance the big hat days in April is a big event. Downtown is turned into a mecca of music, food booths, petting corrals and vendors. It is a part of the rodeo kickoff which is at the last weekend of April.
