Calculate your time carefully, when driving along the river Rhine. The large car-ferries are able to load 50 small cars or several heavy trucks, BUT they will NOT run all day and all night. In fact the ferry between St.Goar and St.Goarshausen will stop operating at 09.00p.m. and your only chance to get across the river Rhine afterwards is one of the bridges in Koblenz, about 40km downstream of St.Goar.
The river Rhine at St.Goar is quite a sensitive area, because plenty of ships have to wait there anchored for the moment, when they are allowed to go through the one-way-passage next to the Lorelei.
The ferry is operated between 06.05 a.m. and 09.00p.m. on weekdays
On sundays it does not start before 08.10a.m.
It will go as soon as enough cars are onboard, or waiting at the other side of the river !
Burg-Express is the name of the small street-train taking you from the centre of St.Goar ( close to the ship-station and the big church) to the castle high above the village. Walking to the castle ( Burg Rheinfels ) will take about 25 minutes and is partly quite steep and although you may go there as well with your private car, a tour by the Burg-Express might make sense, especially when you drive a heavy car or a large motorhome.
The tour is 3 Euros for adults
and 2 Euros for children
The Burg-Express will run every 15 minutes according to the opening-times of the castle:
March 15th till 1st sunday in November 09.00a.m.-06.00p.m.
and in winter at all weekends with good weather 11.00a.m.-05.00p.m.
