What to see and do in Yosemite?!?!

Ok, Internet Friends – I need your expert advice! I’ll be venturing out into Yosemite in the next month and I want to know the BEST things to do and see in the Park! Parking suggestions, good hikes, bad hikes, what to pack, what you won’t need, etc…

I’ve spent one day driving through the park in the past – but I’m looking forward to really making the best of the trip! So if you’ve been, let me know what I need to experience! Thanks!
