Summer oasis: Longhorn Cavern State Park

Formed by an underground river.

It was 95 on the park grounds so trekking underground at Longhorn Cavern State Park, where it's always 68 degrees, was refreshing.

We took the regular walking tour at 10 a.m. on a July Tuesday. There were only eight of us going with the guide. We passed the next group on our way out and there must have been about 25 tourists. So we were lucky to be with a small group.

Things to know before you go through the caves:

• Yep, it's dark. 
• Forget the sweater; the humidity makes the tour shorts-comfortable. 
• The pathway can be slippery. 
• If you are taller than 5 feet, there will be some areas where you have to crouch. There were some moans from those with tetchy backs.
• 52 steps take you down the park path to the cavern entrance. I didn't count them, but I believe the guide, who has walked them many times.
• There is no sitting so be prepared to walk about 90 minutes.
• The guides want tips.

I took these pics with my smartphone, but you can book a photo tour.

Did you hear that? You can book a paranormal tour to hear otherworldly stories.

The caves have been used by native Americans, outlaws and bootleggers.  Today you can have your wedding down there.

Not too many stalactites or stalagmites.

Do you see Lincoln's face?

No climbing or touching is allowed.
