The best way to experience the springs at Balmorhea State Park is to stay the night and get there in the morning when things are calm, shadows are deep, and it's still cool (even in summer). I camped the night before, lucking out with a clear sky to see the Strawberry Moon of the Summer Solstice. The next morning I woke up to a beautiful sunrise and then hit the pool. Most of the people I saw there in the morning had camped or stayed in the cabins-- we all strolled around the pool, enjoying the peacefulness of the morning.
Built by the CCC, so much of the park is beautiful, rustic stonework, adobe, and ironwork. These lovely railings lead down to the crystal clear waters of the spring.
