Our family with young kids had a great stay here. The location is fantastic as you’re isolated enough for it to feel peaceful but only 5 mins to Owaka.
We borrowed the kayaks at the secret river spot and the kids loved it (life jackets provided) and bought some lovely sausages too.
The outdoor deck is awesome for any weather and we used the BBQ every night. Beds are comfy and rooms spacious (except for the twin single room which was perfect anyway for two younger kids).
Regarding younger kids - in terms of safety for preschoolers, the back section is a great space for footie etc but isn’t fully fenced round the sides. However there are lots of board games, kids’ books, kids’ bowls, a bath and a large living area with several spots to hang out in.
No tumble dryer but you can dry things in the living area or on the deck. The bathroom and kitchen are basic but functional and clean.
We loved doing the horse riding with Cara in New Haven, visiting Pounawea, eating at the Bakehouse (can also play table football and pool for a dollar), coffee from Tahatika, Cathedral caves, and Jack’s Bay. But we left feeling there was loads more to see! Would also recommend the Owaka museum - a really well done small museum and community art gallery.
I’d suggest doing more research than we did about which things are open on what days before you travel! Some of the cafes in smaller places had limited days.
