Bring a change of clothes if you plan on participating in the gem hunting activity, as it can get messy.
Allow extra time for the maze, as finding the center checkpoint can be more challenging than it appears.
Sun protection is essential as most of the maze and outdoor features offer limited natural shade.
Do not attempt the stone maze during or immediately after heavy rain, as the granite surfaces become extremely slippery.
Closed on Wednesdays; generally open throughout the year but may close during severe winter weather.
