I cycled from Mapua to Motueka today, along the Great Taste Wine Trail going out but along the Motueka Estuary causeway on the way back . Stopped at the top to admire the breathtaking views.
PS I came back along the causeway coming home : 18 minutes with tailwind – 24+min without, so a no-brainer , since up and around the back of Motueka on the shingle road to the top here would be at least twice as long. There is a “decent” enough road width on that causeway for 99% of the way – but one frustratingly narrow 50 section over a small water channel ; the traffic is fast, but generally OK but do be careful. Of course once you reach the end of the causeway you are back on the Great Taste Trail and all is…….good )
