Pros & cons
PROS
- Historic pioneer route with a genuine sense of discovery
- Solitude and big alpine views away from Milford Road crowds
CONS
- No DOC huts and little to no marking—full self-sufficiency required
- Requires a car shuttle or pickup; Hollyford end is remote
- Serious river crossings and avalanche exposure in shoulder seasons
Park at The Chasm Car Park on SH94 (Milford Road); this is the common starting point.
Unmarked alpine terrain, serious river crossings, steep scree, rapidly changing Fiordland weather, and avalanche risk in winter/spring. For experienced trampers only.
What to expect
This is a rugged, historic alpine crossing through the Darran Mountains, linking the Milford Road (near The Chasm) with the remote Hollyford Valley. Expect lush beech forest and riverside travel in the lower Gulliver and Esperance valleys, then steep climbing into stark alpine basins and over the Grave–Talbot Pass before a committing descent. It’s wild, unmarked in places, and absolutely spectacular when the weather plays nice.
Length-wise, plan for roughly 12 miles (about 19–20 km) one way. Strong, experienced parties often take 12–15 hours of moving time one way and commonly split it into 2–3 days. There are established campsites in the valleys but no huts along the route. This is not a loop—unless you turn around, you’ll need transport at both ends.
Difficulty and hazards
Make no mistake: this is an advanced alpine tramping route. You’ll face serious river crossings, steep scree and boulder travel, and untracked sections where good navigation is essential—especially in clag or fresh snow. Fiordland weather turns fast; avalanches are a risk in winter and spring, and rivers rise quickly after rain. If the forecast is marginal, don’t force it.
Logistics
Most start at The Chasm Car Park on SH94 (Milford Road), then follow the Gulliver River toward the pass and descend the Esperance side to the Hollyford. There are no DOC huts on the track; carry full camping and emergency gear, maps/GPS, and be fully self-sufficient. Because this is a point-to-point traverse, arrange a shuttle or pickup; the Hollyford end is remote.
Natural highlights
Lower down, you’ll walk through dense beech forest draped in mosses, with clear rivers and waterfalls for company. Higher up, subalpine scrub gives way to bare, glaciated basins with panoramic views of the Darran Mountains, including the Mount Talbot area. Keep an eye (and ear) out for kea in the alpine zone.
Best time to hike
Summer (December–March) offers longer days and generally safer conditions. Spring and autumn can work for skilled parties but bring higher chances of snow and avalanche hazard. Winter is not recommended. For a quick taste of the Cleddau’s power without the commitment, the short tourist walk to The Chasm makes a good consolation on stormy days.
Is it worth it?
For experienced, prepared trampers, yes—this is a classic Fiordland adventure with big scenery, real solitude, and a strong sense of history tied to early explorers William Grave and Arthur Talbot. For casual hikers, it’s too serious; choose an easier valley track or a roadside walk instead.
