This is an excellent park to visit, specially if you are looking for some very physical activity. It takes about 20-30 minutes to reach the top, depending on your shape. There are overnight camping facilities and free showers in the restrooms!
Just one thing though- DO NOT TRY TO CLIMB THIS ROCK IN MID DAY DURING THE MONTH OF AUGUST WHEN THE TOP OF THE ROCK REACHES TEMPERATURES OF 120 DEGREES AT TIMES!
