SAIL Amsterdam 2015
SAIL Amsterdam is a maritime event taking place every 5 years in Amsterdam, where boats from all over the world come to the Amsterdam harbour for a few days. Some of the ships can then be visited.
REM Eiland
REM Eiland is a platform that used to broadcast pirate TV and radio from the North Sea but that now sits near the IJ river in Houthaven, in Amsterdam West. The roof can be accessed freely and also has a restaurant. I was there during SAIL Amsterdam 2015, hence all the boats on the IJ.
