Tidevandstrappen is a spot in the industrial port of Nuuk where you can embark on a boat tour. It's the meeting point for your captain and guide, who will take you out into the Nuuk Fjord.
How to get there
Use Google Maps and go by the road and use this route.
There is a stair case on your left side when you start to walk down the hill to the harbour - take the steps to make your route shorter. The steps are located a few houndreds meters after the roundabout.
There is a small wooden shet placed next to the stairs where you can wait inside before your tour starts as it can be cold to wait outside.
