I don't know that it closes. We were there last weekend and you're allowed in whenever.
The gate is open 24/7 to foot and bike traffic but cars are only allowed Monday though Sunday and any federal holiday from 8 to 3:30.
It doesn't close. Open for foot traffic 24. 7
No problem riding bikes to the pump house for sunset. Other riders mentioned the pedestrian gate doesn't get locked.
