Board a fast lake cruiser from Roys Bay and land on Mou Waho — a predator‑free island with a glacial summit lake and rare wildlife. This three‑hour cruise plus guided walk combines steep but short climbing with close‑up conservation stories and wide alpine views.
The lake hushes as the cruiser slides off Roys Bay, mountains folding up behind you and the wind sketching cold lines across the water. Within 30 minutes the shoreline blurs into green rock; Mou Waho rises from Lake Wanaka, its steep flanks pushing the sky up and daring you to climb.

This small island is a glacial remnant: a rocky knob scoured and left with a shallow, perched lake at the summit. The site is managed by the Department of Conservation as a predator‑free reserve, and the walk turns into a live conservation lesson — look for the rare Buff Weka, a flightless bird once lost from the mainland, and the cryptic mountain stone weta among rocks and tussock.
Culturally the lake and islands reflect Wanaka’s early tourism era; you’ll pass Ruby Island, known for its 1920s dance‑hall history, before your guide lands the skiff. The guided route climbs roughly 150 m over 1 km — short, steep, and exposed in places — then eases into a rim walk around the small glacial lake with a tiny island inside it: an island in a lake on an island in a lake.
Plan for a three‑hour outing: 30 minutes each way on the water and two hours ashore. Wear grippy shoes, pack 1–1.5 L of water, and layer for wind and sun; weather changes fast on the lake. Boarding is punctual at 8:45 am, trips depend on minimum numbers and fine conditions. Move deliberately on the trail to protect fragile ground and wildlife; your guides balance interpretation with conservation-minded route choices so you leave the reserve as you found it.
challenging.
3 hours.
Good cardiovascular fitness and the ability to manage a short, steep uphill with uneven footing are required.
You’ll have about two hours ashore; the guided loop includes a steep 1 km climb with 150 m elevation gain and time at the summit lake.
The walk is short but steep and uneven — not recommended for those with serious mobility, spinal, or cardiovascular conditions; assess children’s abilities to manage a steep climb.
Guides often point out Buff Weka and native birds; you may also see mountain stone weta and other small native fauna in the reserve.
Trips depend on favorable weather; if canceled you’ll be offered an alternative date or a full refund per the operator’s policy.
