I like hiking and rock climbing and affordable travel. I’ve done the outward bound thing, and NOLS is too long and expensive, any short-term options in the US, South America, Caribbean that might be exciting?

I am planning a Boy Scout high adventure and am looking for a good caving/spelunking and rock climbing activity. Anybody know of any good guided caving adventures out there? We are in the Norther Virginia area and could travel up to 4 hours. All the boys are between the ages of 16 and 18. Thanks!
Lurray Caverns is a little too commercial. The guys are looking for something that is a little more rugged and doesn’t have hand rails and lights.
