From M25 J25, Go north on A10 to junction with A121 for Cheshunt (traffic lights). Turn right here, and at roundabout (with fountain) turn left, then immediately right into Windmill Lane, heading for Cheshunt Station.
At Cheshunt station, go over the level crossing, then after 100M you go over a bridge, and bear left. Herts Young Mariners Base is the new building just through the gates, with a gravel car park.
