About This Route
Key Summit offers a rewarding 3-4 hour day hike on the Routeburn Track, accessible from The Divide car park along the Milford Road in Fiordland National Park. This 6.6-kilometer loop climbs 400 meters through beech forest to alpine meadows with 360-degree views of the Humboldt and Darran Mountains. It's a side trip from Milford Sound drives, ideal for those without multi-day commitments. DOC recommends checking track status at the visitor center; the route features boardwalks and slips after rain.
Safety Considerations
Variable Fiordland weather dominates; fog, wind, and rain can reduce visibility on the exposed summit, leading to disorientation. Register intentions with DOC via their online portal for day hikes over 3 hours. Watch for slippery roots and mud; wear grippy boots like Salomon X Ultra. Kea birds may damage unattended gear, so keep packs close. Hypothermia risk rises above the bushline; turn back if winds exceed 50 km/h. Follow the track strictly to avoid scrub; no off-trail shortcuts. Families with children should assess fitness for the steady climb.
Essential Gear
Layer with a fleece mid-layer, Gore-Tex jacket from Outdoor Research, and wool hat. Pack 2 liters of water, energy bars, and a whistle. Use an Osprey daypack with hydration bladder. Include sunscreen, lip balm for UV exposure, and insect repellent for sandflies at lower elevations. Compass and Fiordland topo map essential; Gaia GPS app for offline navigation. Compact first aid with blister plasters.
