Nelson is about 1hr 45min, Mapua a further 30mins, and Kaiteriteri 30mins beyond that.
You can either travel via Queen Charlotte Drive, or head in towards Blenheim as shown on the map, the distance is a little more but the travel time is about the same.
The journey takes you through Havelock and Pelorus Bridge see separate post.
There is plenty to see but for a day trip I mention two of my favourite places, Mapua Wharf and Kaiteriteri.
Mapua Wharf
this is the old apple loading wharf, but is now a collection of shops, galleries, restaurants, cafes and bars, click here.
The Golden Bear Brewing Company, is a boutique brewer, typical of many.
Kaiteriteri
Right on the edge of Able Tasman National Park, beautiful beaches, swimming, kayaking, picnicking or places to eat.
