Best waterfall in the park
Perhaps I'm biased because this was the first thing we did in Yosemite park, but this hike brings you right to the base of the falls. Looking up you can see mist. Often just mist, but at times the mist was thin you could see the falls spilling over the rocks.
We saw this in late April in the morning, when the falls were gushing and the sun was almost directly above the crest. At the base, everywhere you look is a rainbow.
This hike doesn't have a lot of scenery building up to the falls, but the falls itself is spectacular.
I recommend coming in from the north side instead fo the busier parking lot.
