I go up every year, east side about 32-34 km up, it's not great if you have small kids but older kids is fine. You do have to deal with grads and ravers though so be prepared. This past weekend we went up and they were pretty rough I wouldn't want to bring my young children up there. But it is a nice place.
Love you forever dad, R.I.P. Fingers.
