Kenepuru Sound

[1] The drowned valley is an arm of Pelorus Sound / Te Hoiere, it runs for 25 kilometres (16 mi) from the northeast to southwest, joining Pelorus Sound a quarter of the way down the latter's path to the Cook Strait.

Some of the small side arms of the two sounds are only hundreds of metres apart, at Te Mahia Bay and Portage Bay, but are separated by a steep serrated range of hills.

[2] Not surprisingly, one of the settlements on this stretch of coast is called Portage, named for the simplest method of passing between the two sounds.

From there, unsealed roads continue further and along the less populated northern shore.
