On weekdays, Sturla offers a comfortable scheduled Tigre-Buenos Aires "Proa Urbana" commuter service on the River Plate that can be booked by both suburbanites and tourists. The one-hour trip to the Tigre boat terminal from the dock beside the Ferrylíneas terminal in Puerto Madero in BA costs 15 pesos one way, including refreshments and a free newspaper. But that's if you wish to travel from Tigre to Puerto Madero at 7.30am, or from Puerto Madero to Tigre at 6.30pm. At 10am they run a two-hour Delta tour from Puerto Madero that costs 62 pesos.
