Robber Baron Open House

Robber Baron Open HouseNovember 11, 2017, 9:00am155 Camellia Dr, San Antonio, TX 78209-2138, United StatesThe next Robber Baron Open House is scheduled for Saturday, November 11, 2017 from 9am to 3pm. This special event only occurs once every 18 months, so don’t miss this rare opportunity to explore a wild cave right here in San Antonio!

The Open House is open to the public. It is free, although we request donations to help maintain the preserve. We will also have the famous Robber Baron Cave Map t-shirts for sale, and we will have a photographer to take your group photos in the cave with printed photos available on surface when you exit.

Note that this is a “wild cave”. There are no sidewalks or handrails, and you might get a little muddy. We suggest you wear jeans, an old t-shirt, and sneakers or boots.

This year there are three options for touring the cave:

• Just show up and take a self guided tour through the cave on a first-come basis as space is available.

• Sign up in advance for the self-guided tour for specific times and skip the lines.

• Take a small group guided tour to off-trail locations not visited by the self-guided tour – space is limited and must be reserved in advance. You must be in good physical condition for this tour. Ages 12 and up only.

Sign ups for the self-guided and guided tours will be available on the TCMA website starting on October 10.
