Come monsoon season (July–September), Bhushi Dam becomes possibly the most popular weekend attraction in the entire Mumbai–Pune belt — and for good reason. The dam overflows in dramatic sheets of water that cascade down the stepped spillway, creating a natural water park that draws families, couples, and groups looking to wade in the cool gushing streams. The surrounding greenery is at its absolute peak, and the waterfall backdrop makes for incredible photographs.
Be extremely careful in the water — the current is deceptively strong and people have lost their footing. Wade only in the shallow sections near the steps, not downstream.
