A MUST! The Pool at Balmorhea State Park is for the true adventurers! One of the world’s largest spring-fed pools at 25 feet deep and 3.5 million gallons of water, it’s perfect for those who love nature and wildlife. It is popular for scuba divers since it is home to a variety of endangered fish, turtles and more. If you’re not into the scuba thing, just bring some goggles and a snorkel to check out what’s swimming under your toes. It’s quite a drive but there are the San Soloman Spring Courts built in the 30’s or pitch a tent in Toyahvale, TX. My preference would be to stay in nearby Marfa at El Cosmico!
