The simple answer is yes. The more in depth answer is...it depends on if you are a premium member or not. If you are, thru the geocaching app you can save a pocket query and you can open it without internet connection. If you are not a premium member, I am not sure why you arent, but to each their own. For the android tablet you can download a program called c:geo. This is totally free, and it has capabilities of saving offline maps and all of the information about the cache.
