Enchanted Rock is a really big rock that sits on the ground in Texas. It is so big that people come from all over to see it and climb to the top.
Long, long ago, there was a lot of lava that flowed and cooled down near the rock, and over time, the ground eroded away leaving the rock behind. Scientists call the rock a type of granite.
What makes Enchanted Rock special is that it has lots of tiny crystals inside of it that make it sparkle in the sunlight. It also changes color depending on the time of day - sometimes it looks gray, and other times it can look pink or orange.
Enchanted Rock is a special place for many people. Some believe it has magic powers that can give you good luck or make wishes come true. That's why some people call it "Enchanted" Rock.
