I'm very glad we ended up staying at Lake Hāwea, as opposed to Wanaka. The lack of tourist clutter was incredibly peaceful and having the ability to walk down the lake front and essentially have the beach to yourself was spectacular.
The house felt cozy, like a classic NZ bach. We only had four of us staying here, but it allowed us to spread out and enjoy our own space. I imagine having a larger group would be great too though.
We thoroughly enjoyed our stay and would definitely stay here again.
P.s. The knives in the kitchen could so with a sharpening, or replacing!
