If you come to Denmark by plane, you can take the Metro at the airport to Nørreport and switch train to Helsingør. After 5 stops you are in Vedbæk
There will be a ticket-machine where you can buy the tickets for the whole trip to Vedbæk
The trip takes about 60-70 minutes
To get to my boat from the station is very easy. 7-10 minutes walk
