If you are at the northeast corner of Carondolet Park; Holly Hills and Grand; you can enter the park by going right, or left, following around the circle, 3/4 of the way around, then you are heading east, toward the YMCA. If you make a right off of Grand, heading west, you can only go to the first intersection in the park and you must go left, uphill, toward the boathouse by the lake. You can drive only to the left, and then be heading back toward Grand, where you can go either left or right toward Loughborough. Other entrances to the park are closed.
