A Linux Bier Wanderung (engl. Linux Beer Hike) is a week-long event typically held in a small town in Europe where a group of like-minded open source enthusiasts gather to share knowledge, hike, enjoy various liquid refreshments (non-alcoholic and alcoholic) and first and foremost have fun! Everybody is expected to look after their own travel logistics including accommodation but the website promoting the event (including this one) typically offers some guidance and provides information about where to look and what to expect. The event is generally free of charge (ie. no registration fee or similar) but the costs of the Hall (rented by the organiser(s) of the event) is shared between the participants. The central purpose of the Hall is to serve as a base camp for the various activities and as a gathering place for meeting, sharing ideas, talks, etc. You can find more details here. There is also a mailing list covering various topics around the LBW and is used for communication between evetns (may require registration).
