The North Entry Station and Castle Creek Boat Ramp (a.k.a. 4 Lane) will be temporarily closed the morning of Saturday, March 30, for a trail and road run special event. No vehicle or boat entry will be permitted during this time. As soon as runners have cleared the North Entry Station, access will be granted. Runners will be starting at the boat ramp and heading up Castle Creek Drive out of the park, and along Castle Hot Springs Road up to Crown King.
