You can do a day trip to Caves Branch from various tour operators in AC or CC. Check the websites for Seaduced, SEArious, etc. Or your hotel tour desk can set it up. If you want to go to stay for a night or 2, you would go back to BZ City and have the lodge pick you up, take a bus, hire a driver, etc. It is about 1 1/2 hrs from Bz City. They have a link on the lodgings section of this website. Reservations highly advised for the stays there.
