UNOFFICIAL Spectator Guide – 50th DETH Rally Thessaloniki 16 & 17 Sep 2017 – Route Maps & Timetable/Schedule

The Street & Circuit unofficial spectator guide to the 50th running of the DETH Rally – Information in Greek here and official website of the DETH Rally

Motorsport is dangerous for spectators and participants. Always be aware of your surroundings, you are responsible for your own safety.

Rally runs on the 16th and 17th of September 2017. Amazing scenery to get to the stages and on the stages. Stage 1 and Stage 6 are my personal favourites.

The roads used in the stages close around 2 hours before the stage starts. If you want to drive into the stage to spectate I would recommend getting to your location 2 hours before the start of the stage. Just to be on the safe side.


DAY 1 – 16.9.17
