The hibernation cave just stores dragons, it is useful in levelling up the shrines because it requires 50 dragons which share an element levelled up for level 10 to get a silver shrine or level 15 to get a gold shrine. When you're trying to level up all the shrines thats too many dragons to store in your park so instead of feeding up dragons and then selling them off you can store some in the hibernation cave.
