Scheduled Summit Trail tours are on the third Saturday of the month starting April, May, September, October, November, and December. Private tours are available for groups at other times. The Granite Gripper is an annual

competition that acts as a fundraiser for park conservation through the Friends of Enchanted Rock. Emphasis is placed on activity safety and ecological preservation. Visitors are asked to keep human incursion at a minimum by not disturbing plants, animals, or artifacts. Pets are not allowed on the summit trail. Federal and state statutes, regulations, and rules governing archeological and historic sites apply. The state Game Warden as a commissioned peace officer is authorized to inspect natural resources and take any necessary action for their preservation.

culture. Based on archaeological evidence, human habitation at Enchanted Rock can be traced back at least 10,000 years. Paleo-Indian projectile points or arrowheads, 11–12,000 years old, have been found in the area upstream and downstream from the rock. The oldest authenticated projectile point found within the present-day park is a Plainview point, dating back 10,000 years.

Such vandalism is a state felony in Texas, carrying "a penalty of up to two years in state jail and a $10,000 fine if convicted".

Expansion

In August 2024 TPWD approved the purchase of 630 acres adjacent to Enchanted Rock, which expanded the size of the park by almost 40%. In January of 2025, an additional 3,073 acres of adjacent land was purchased, almost tripling the park's size. The funds for these purchases came from the $1 billion Centennial Parks Conservation Fund, which was created in 2023 during the 88th Texas Legislature with the passage of S.J.R. 84.
