Turn left onto Go Gang bridge (now part of short-cut to Long Son island) after Metro turn-off but well before Ba Ria on main highway from Vung Tau. The bridge can be plainly seen from the road and is also signposted at the turn-off: "Go Gang" with arrow pointing left.
Start trail over first bridge to view fishing villages and oyster farms left and right. Over bridge about 200 metres turn right at small derelict house. Go ahead several hundred metres until oyster farms. Follow trail forward and left around oyster farms, past very close to at least one small thatched-roof house with dog (owner OK, but ask first).
Eventually leave oyster farms to reach newly-constructed road, turn right for few hundred metres then left to cross new road opposite green and grey house (1.4 km in a straight line west from where you turned right at small derelict house).
Through more oyster farms for several hundred metres then bear left into residential area (heading back towards first bridge).
Follow dirt track until you reach the school then left and almost immediately right to continue through residential area (now running parallel to newly-constructed road heading back towards bridge). Anyone missing the right turn after left at school will go directly out to newly-constructed road, hence short-cutting the trail!
Almost reach the river then left towards newly-constructed road, emerging just behind first café on left as you came over the first bridge from main Vung Tau-Ba Ria highway. Into café grounds for Down Down, or can be held closer to foot of bridge to the east of the café in large open, grassy area.
