We have friends with a bach in the Hurunui in the high country of Canterbury, New Zealand and we joined them there for a weekend.
My other half went fly fishing but I had a lot more fun swimming in the deep water pools. It is fairly safe to do this in the high country as there is not so much run-off from agriculture, particularly as there are no dairy farms there.
Molly learned to swim across the river, which she preferred to old rickety bridges. She taunted her new friend, Marlowe, who was not that keen to get wet.
