Lake Sumner

Lake Sumner, cradled in the remote Lewis Pass National Reserve, is a shimmering gem of alpine beauty that rewards those who venture off the beaten track. This turquoise lake, surrounded by beech forests and towering peaks, offers a true wilderness escape in the Canterbury region. The journey here is an adventure in itself, with gravel roads winding through stunning landscapes, making it a perfect detour for self-drive travellers seeking solitude and raw nature.

Highlights & What to See

• Lake Sumner Track: A spectacular multi-day hike that circles the lake, offering panoramic views of the Southern Alps, tussock grasslands, and pristine river valleys. Day walks to the lake shore are also rewarding.
• Kayaking & Fishing: The clear, cold waters are ideal for kayaking and trout fishing. Bring your own gear or hire in Hanmer Springs; the lake is a haven for anglers.
• Wildlife Spotting: Keep an eye out for native birds like kea, falcons, and the elusive blue duck (whio). The surrounding forest is alive with birdlife.
• Hot Springs at Hanmer Springs: After a day of hiking, soak in the famous thermal pools back in Hanmer Springs, just an hour's drive away.
• Lewis Pass Scenic Reserve: Explore nearby short walks to waterfalls and alpine bogs, such as the Marble Hill Walkway, which showcases unique limestone formations.

Suggested Time to Spend

Lake Sumner is best enjoyed over two days if you plan to tackle the full track or kayak. For a day trip from Hanmer Springs, allow at least 4–5 hours for the drive and a short walk to the lake shore. The gravel road (Lake Sumner Road) requires careful driving, especially after rain, so factor in extra time. Overnight stays are possible at the Lake Sumner Hut (book via DOC) for a true backcountry experience.
