How to get to us:

Harbour Splash is located at the Old Pier in Coal Harbour near the west pier.  We recommend to take public transport for your trip to us – the DART and bus stops are very close by and there is no designated parking for Harbour Splash in the area, there is only very limited pay parking available in the harbour. We don’t want you to miss your slot because you couldn’t get parking.
