Normally, you can no longer hike around the reservoir due to construction (fence). Immediately after the bridge, turn left, where the path begins. Weather: Drizzle, rain ☔️-drizzle. The path around the quarry lake is good for hiking (once through the gravel pit (careful!!!). The old trees are amazing!
