The most convenient (and eco-friendly) way to get to the conference hotel is by train. Take the "Lokal" northbound train to Steinkjer, and get off at Røra station, where you will be picked up by the organizing committee and taken to the hotel.
Train times are the same for Tuesday and Wednesday, and they generally go every 30 or 60 mins until around 19:00 (show earlier/later departures in the links above).
PS: If the trains do not work with your flight schedule, please contact the organizing committee (Øystein) and we will pick you up at the airport. In any case, we would like to know your estimated time of arrival.
For your return on Friday we will arrange taxis/shuttle buses to accommodate your needs.
