The official website containing information for Timms Hill County Park shows the Hours of Operation (i.e. the hours the park gate is open) as being 7:30 AM - 9:30 PM. However, this is not true. In advance of visiting this HP this past weekend, I contacted the Parks Department and found out the gatekeeper commonly closes the park gate by dusk. In fact, the gate even says "Open 7:30 - Dusk". If planning a visit to Timms Hill County Park and wanting to verify the hours the gate will be open, contact the Parks Department at (800)269-4505.
