The flow gets lower toward the end of the season, so the earlier in the summer the better. There is a fee of $5 per car for the day.
The later in the day you go, the busier it becomes. If you can go during the week there are fewer people, but it won’t really impact your wait time.
The water is cool, so summer is the best time to go.
