Sure was hot when we visited the falls. Camping at the falls is not really a good option as the sites are right in the middle of where all of the people visiting for the day go through. I would suggest camping nearby (maybe near the snake river). There are not clear signs as to where to hike for trails to get you to the bottom of the falls. Some of the hiking is pretty scary as there are no barriers if you were to fall. Definitely worth the visit though!
