Hamilton Pool grotto is a historic pool located just 45 minutes outside Austin. In the summer it can get very busy so its best to get there early. During warm-weather days when swimming is allowed the number of people trying to visit the pool greatly exceeds the number the canyon can accommodate so a waiting line forms and people are allowed to enter as others leave. The waiting time is typically one and a half hours.
