The Batcave was unfurnished with only storage for the Batsuit and the Tumbler. It was a big cave system with a river, three water falls, a ravine, and more. The entrance and exit for the Tumbler was located on a cliff, behind a waterfall. Batman also gave Rachel Dawes the antidote for the Fear Gas in the Batcave when she was on the brink of insanity. Towards the end when Wayne Manor was on fire, Alfred saved Bruce's life by taking him down to the Batcave in the secret elevator. After Wayne Manor was destroyed, Bruce moved his operations to his Warehouse.
After Wayne Manor was rebuilt, so was the entrance to the Batcave. It mostly remained the same as in Batman Begins, but had more equipment including a high-tech super-processing computer. Bruce came to the cave in a few occasions of the film as did Alfred. After the "death" of both Bruce and Batman, John Blake inherited the Batcave, which implied that Bruce had intended John to take over the mantle of Batman.
