Heidelberg Germany
Heidelberg sits in the Rhine-Neckar valley where the Neckar river cuts through the Odenwald hills before opening into the Rhine plain. The castle above the old town is one of the most-visited ruins in Germany, and the Altstadt below it is well-preserved and genuinely pleasant to walk through. Heidelberg University, founded in 1386, gives the city a permanent academic character that makes it a natural host for specialist conferences. The conference crowd here tends to be security researchers and technical practitioners, drawn by events like Troopers. Rail connections are good: ICE trains reach Frankfurt Airport in about 45 minutes and Stuttgart in around 40 minutes. The city is compact enough that most hotels are within walking distance of the main conference venues.
- Heidelberg Castle - The ruined Renaissance castle above the old town is the city’s defining landmark, with panoramic views over the Neckar valley from the terrace.
- Alte Brücke (Old Bridge) - The 18th-century stone bridge across the Neckar is the most photographed spot in the city.
- Philosophenweg (Philosophers Walk) - A hillside path above the north bank of the Neckar with views back over the castle and old town.
- Heidelberg University Library - One of the great German research libraries, with a collection of medieval manuscripts and a fine reading room.
- Hauptstrasse - The main pedestrian street through the old town, lined with shops, cafes, and restaurants.
Frankfurt Airport (FRA) is the closest major hub, about 80 km north. Direct ICE trains run from Frankfurt Airport regional station to Heidelberg in around 45 minutes. Stuttgart Airport (STR) is about 90 km south with connecting trains.
Heidelberg is highly walkable in the old town and central areas. The tram network connects the main station to the old town and university areas. Bikes are popular. Most conference venues are reachable on foot from central hotels.
Spring (April-June) and autumn (September-October) are ideal. Summer is warm and busy with tourists. The Troopers conference in June catches the city in good weather.

Heidelberg splits between the Bahnstadt district by the station and the old town, and the two are a comfortable walk apart. The halle02 venue is in Bahnstadt, with the ibis Hauptbahnhof 200 m away, the Crowne Plaza City Centre at 400 m and the NH at 800 m, which makes that side the practical base for anything held there. The old town is the reason to visit: the Hotel Zum Ritter St. Georg at 2.7 km is a sixteenth century building on the Hauptstrasse, and the Europaeischer Hof at 1.5 km is the grand option, both within reach of the castle and the river. Note that Troopers 2027 has not named its venue in our data, so do not assume it is at halle02; check before you book on that basis. Heidelberg is small, extremely popular with visitors and books up in summer, so reserve early whatever the conference dates.
