Key Summit

Key Summit is a must-do hike in Fiordland National Park, offering one of the best panoramic views in the region without requiring a multi-day tramp. The trail begins at the Divide shelter on the Milford Road, following the Routeburn Track before branching off to the summit. The climb is steady but manageable, and the reward is a stunning 360-degree vista of alpine tarns, sculpted peaks, and the Hollyford Valley. The summit's boardwalk and interpretive signs make it feel like a natural classroom, explaining the unique alpine environment and its fragile ecosystem.

Highlights & What to See

• Alpine Tarns: Sparkling glacial lakes dot the summit plateau, reflecting the surrounding peaks on calm days.
• Panoramic Views: Gaze across the Darran Mountains, Humboldt Mountains, and the deep cleft of the Hollyford Valley.
• Subalpine Flora: In summer, the summit bursts with colour from mountain daisies, buttercups, and cushion plants.
• Routeburn Track Teaser: The first section of the hike follows the world-famous Routeburn Track, giving you a taste of this Great Walk.
• Interpretive Boardwalk: A well-maintained boardwalk protects the fragile alpine environment and provides informative panels about the landscape.

Suggested Time to Spend

Plan for 3–4 hours return from the Divide car park. The 7 km (4.3 mi) return walk gains about 400 m (1,300 ft) in elevation. Start early to avoid afternoon clouds that often obscure the views, especially in summer. Combine with a short walk to Lake Marian or a drive to Milford Sound for a full day in the Fiordland area.

Nearby Areas Worth Combining

• Milford Sound: A 30-minute drive from the Divide, this iconic fiord offers boat cruises, kayaking, and stunning waterfalls.
• Lake Marian Track: A 1.5-hour return walk to a beautiful alpine lake, starting near the Hollyford Road turnoff.
• The Chasm Walk: A short 20-minute loop near the Milford Sound tunnel, showcasing powerful waterfalls and sculpted rock formations.
• Routeburn Track: For more ambitious hikers, the full Routeburn Track is a 3-day Great Walk connecting to Glenorchy.
• Te Anau: The nearest town (about 1.5 hours' drive), offering accommodation, dining, and lake cruises to glowworm caves.
