By Plane
International guest might want to use the airport Frankfurt and then travel by the train using the route Frankfurt-Darmstadt-Bickenbach.
Since it's 7 km from the station to the con-site you prob'ly should inform some staff member or gopher to pick you up. Do this in advance (tell H'Lven per e-mail when you're going to arrive) or give us a call from Bickenbach station
(telephone number: 06257-8846 ).
We will provide a pick-up-service.

By Train:
You can use HAFAS, the German internet railway information service, to look for a train suitable to you.
This link provides you with a German CGI-Form whereas this link leads you to an English form. (Thanx to DocO for providing this hint.)

If you are feeling courageous, you might even use the bus.
Just enter a bus marked "Linie K 50" driving from Statio Bickenbach to Seeheim and leave about 10 minutes later at a bus station called "Neues Rathaus".
Follow the map - the con-site is just 500 meters away.

By Car:
If you're going to use a car, you should drive the A 5 (autobahn/highway/motorway) until you reach the Abfahrt 28 (exit 28) named Seeheim-Jugenheim.
You have to take the exit pointing towards Seeheim-Jugenheim and then stay on this road until you enter Jugenheim.
At the first crossing (Picture 1) you turn left to Seeheim.
After you've entered Seeheim you turn left at the 3rd crossing (Picture 2 and Picture 3) entering a street that leads directly to the youth-hostel Falken.
You have to turn left immediatly after entering this street and then you have to follow the Sandstrasse (Picture 4).
Stay on this road until you see the youth-hostel on your right side, that'll be after about 500 meters.
Parking lots are available around the con-site.
If all this sound somewhat ridiculous (I was never good at descriptions) we have scanned in two maps: An overview (Picture 00a) and a detailed map (Picture 00b). Please notice that those 2 maps are about 2 MBytes (in sum).
