Firstly, thank you.

Secondly, with a little bit of know how and a lot of luck. Firefalls ( Horsetail Falls ) is a section of granite on the east side of El Capitan in Yosemite. In February for a few weeks each year the sun hits this part of the wall just right. Now of course you need a waterfall so that means there needs to be plenty of snowmelt or precipitation and it has to be a clear sunny day and warm enough not to freeze. Otherwise, get your reservations make the trek and find the spot and the rest is easy!
