From O Grove, we will travel along the S shore of the ría of Arousa (a ría is a fjord-like bay, but with a tectonical origin, linked with the flooding of the low valley of a river), reaching the S point of Sálvora island or the N channel of this island, depending on tides and/or sea condition. Then, we will sail W towards the 12 nm line, near the Arousa canyon, facing S to the nearby slopes of the Vigo canyon. Back trip will be performed after lunch, travelling NW near the W side of Ons archipelago towards O Grove.
This route would be changed depending on sea and wind conditions.
