I did a run through the cave before, but never experienced anything else. It was a great time and the party boat ride through the cave was awesome. I can't wait for them to announce the Halloween plans.

This was a wonderful event. The Cavefest should be an annual thing.. They have soo much potential for this place. Wouldn't it be romantic to have a candle light dinner down there. Just a thought for Valentines Day. The boat cruise was amazing and our tour guide could not have been nicer.. overall I would go back in a minute for another event and bring lots of friends..

What You'll Get

Writing "stay cool" in a friend's yearbook can remind them that even after high school ends, they should keep their body temperature below 104 degrees to avoid total organ shutdown. Have a cool summer with this Groupon.

Choose Between Two Options

  • $35 for two VIP tickets to Cave Fest 2013 on Saturday, August 10 (a $70 value)
  • $69 for four VIP tickets to Cave Fest 2013 on Saturday, August 10 (a $140 value)

On Saturday, August 10 from 2 p.m.–10 p.m., Crystal City Underground transforms into a subterranean club. VIP tickets include a barge ride and admission to a concert featuring decade-straddling rock, pop, and country band Lucy's Palace; dance-rock group Dance Floor Riot; and classic-rock outfit Superjam, which was named St. Louis's best tribute band by the Riverfront Times in 2010. Food and drink will be available for purchase, as well as activities such as laser tag, kayaking, and volleyball. A video production crew will be in attendance to film the event for an upcoming Kickstarter promotion, so every guest has the chance to be a part of the promotion video. Proceeds from the event go to benefit the nonprofit Community Improvement Association of Crystal City and its efforts to build a new community center.

About Crystal City Underground

In place of what once was a sand mine, Crystal City Underground has transformed more than 6 million square feet—approximately 200 acres—of sub-surface space into a climate-controlled entertainment facility. With 30- to 40-foot ceilings, thick pillars carved out of rock, and a lake, it presents visitors with a multifaceted underground experience, one that already includes sand volleyball, disc golf, and weekend barge rides. Future plans for Crystal City have it adding more recreational amenities en route to becoming a subterranean cultural and convention center.
