It's August in Baltimore, and it's hazy, hot and humid. By now the fun and novelty of summer have surely worn off. Who cares about getting a tan, hitting the beach or driving with the top down anymore, when all you really want to do is stop sweating?
Actually, there is a place where it's always cool -- 100 feet underground. Even when it's 100 degrees outside, inside an underground cavern it's a cool 52-54 degrees all year long.
There are close to 100 commercial caves in the United States, and plenty are within a three-hour drive of Baltimore. If you're planning a trip to any of the caverns listed below, it's a good idea to wear comfortable shoes suitable for walking, as walkways can be wet and gravelly. Most children will enjoy a cavern tour, but very small children may be frightened to be underground for an entire hour. Strollers are often not permitted inside caverns. You may also want to take a sweater.
