What is the best/fastest/cheapest way to get to the Open Air Museum from the center of Copenhagen?
Suspect you will have to settle for no more than 2 of 3 of your criteria.
You can look up the public transport options on www.rejseplanen.dk
Page 92 of Rick's Scandinavia book suggests S-Tog to the Sorgenfri stop, then walk 10 minutes to the address Kongevejen 100 in Lyngby. The museum's own web site also mentions bus options and you can see the bus stops on Google Maps: https://en.natmus.dk/museums-and-palaces/frilandsmuseet/practical-information/.
Thank you so much!
