Before moving to Texas, I wanted to do all the things in CA that I should have done while living there but never did.
One of them was hiking to the top of Half Dome. Going past the waterfalls was one of the highlights. We camped just above them, spent the night, and then went up the Ladders to the top of Half Dome the next day, and spent the night at the campground.
Third day we took a different trail back down to the parking area to see more of the Park.
The campground was overrun with black bears. At least a dozen were visible from the campsite at any given time. It was required that everything edible was put into metal containers that they had there because of the bears. One couple had their backpack destroyed by a bear that ate their 35mm film. We didn't have tents, we just slept on pads on the ground. I woke up in the morning with a fresh bear turd about five feet from my head. I'm glad I slept through that!!!
It was one of the best backpacking trips that I've done.
