Mou Waho is most celebrated for Arethusa Pool, where there is a small rock protruding above the stagnant lake level. This makes it an island on a lake on an island on a lake on an island in the ocean.
You will need a watercraft to access the island and good knowledge of Lake Wanaka’s weather conditions.
Paddle Wanaka run trips out there.
From the picnic area and toilet, the track winds up through the tea tree forest to Arethusa Pool.
It’s a short climb to the summit.
Be careful of the drop offs!
Mou Waho is 120 in size and is a resistance cap of rock, which was not bulldozed by the advancing Wanaka glacier. Arethusa Pool is a glacially scoured hollow.
All of the original matai and totara forest was destroyed by successive fires. It is now regenerating tea tree.
The island was declared pest free in 1995. It is a sanctuary for the mountain stone weta and the Southern Alps gecko.
200 buff weka make their home here, following introduction from the Chathams in 2004. This subspecies was extinct on the mainland since 1920, exiled to the Chathams and then reintroduced. Wally and Sally are the favourites and their colleagues love scrounging for tidbits. This is tantamount to junk food for them, so let them forage.
In 1863 Alfred Pinn established a wharf and cottage on the island.
