Lake Poteriteri / Potiritiri

Overview

Lake Poteriteri sits in the far south of Fiordland, a long, dramatic basin walled by steep, forested hills and drenched in classic Fiordland rainforest. It’s the largest lake in New Zealand without road access, and it feels every bit as remote as that sounds.

Why it’s special

This is Fiordland at its most untamed: wild shores, deep solitude, and zero drive‑up viewpoints. If you want a genuine wilderness experience—no crowds, no café, just you and a giant lake—this is the one.

Access and facilities

There are no roads to the lake. Reaching it typically means a serious multi‑day backcountry mission or a helicopter drop. Facilities are almost non‑existent, with the exception of the small Lake Poteriteri Hut (6 bunks) on the shore. Information online is sparse and sometimes outdated, so verify hut status and current conditions before you commit.

What you’ll see

Expect lush temperate rainforest right to the water’s edge, steep valleys, and a sense of scale that’s hard to grasp until you’re there. The shoreline is mostly wild and track conditions can be rough and slow going.

Wildlife

Specific sightings aren’t well documented for this lake, but Fiordland forests and waterways commonly host native birds such as kākā, kea, and whio (blue duck), with deer present in the backcountry. Treat it as a bonus if you encounter them.

Best time to visit

There’s no “busy” day here—crowds aren’t the issue. Go when the forecast offers a stable weather window; Fiordland is notorious for heavy, fast‑changing rain. Early and late light can be gorgeous for photography when the wind drops.

Know before you go

This is an advanced objective for experienced trampers. Tracks can be overgrown, navigation is tricky, and you’ll need full self‑reliance: map/GPS, extra food, emergency gear, and a solid weather plan. If you’re considering fishing, start by checking regional regulations and current access notes for this specific lake.
