Saint Arnaud

Overview

Saint Arnaud is the compact, no‑frills gateway on the north shore of Lake Rotoiti. It’s the place to grab last‑minute supplies, check track conditions at the Department of Conservation (DOC) Visitor Centre, and step straight onto lakeside jetties for those classic mirror‑water mountain views. The vibe is alpine and understated—more trail boots than boutiques.

What to Do Nearby

• Classic jetty photos on Lake Rotoiti, with mountain backdrops and often‑visible, protected eels cruising the shallows.
• Short lake‑edge rambles from the village, including the Peninsula Nature Loop that links the waterfront to Kerr Bay and can be mixed with the Moraine Walk/Black Hill Track for more variety.
• Bigger day out: head up Mount Robert/Pourangahau via Paddy’s Track to Bushline Hut for sweeping views, returning on the alternate track as a loop.
• Full‑day challenge: “Loop the Lake” around Rotoiti (~24 km). Expect a more technical west side, a Travers River crossing at the south end, and easier going on the east.

On the Water

• Lake Rotoiti water taxi offers scenic trips, drop‑offs for walks, and kayak hire—handy for starting at the far end and walking back to town.
• Trout fishing is popular in the lakes; you’ll need a trout licence and, where required, the back‑country endorsement.

Biking and Winter

• The nearby Teetotal area has a growing mountain‑bike network (50+ km) with options for all levels; in colder snaps a natural skating pond can form when it freezes.
• Winter doesn’t shut things down—Rainbow Ski Area in the St Arnaud Range keeps the village humming as a year‑round base.

Camping and Places to Stay

• Kerr Bay Campsite (by the village): open year‑round with bookings required. Expect powered and non‑powered zones, hot showers by token, laundry, and a dump station.
• West Bay (Jetty and Buller zones): summer‑only (bookings required), no powered sites, forested feel near a boat ramp.
• Teetotal Campsite: just south of the village among MTB trails; dogs are allowed here (the national park proper is dog‑free). Alpine Lodge and holiday homes anchor the in‑village lodging scene.

Practicalities

• DOC Visitor Centre (typically 9:00 am–4:00 pm daily) is your stop for track updates, weather, maps, bookings, and Kerr Bay shower tokens. Hours can change seasonally.
• There’s a combined general store/service station/tearooms; overall, services are limited, especially mid‑week and in winter—plan ahead.
• Pack‑in/pack‑out: there’s no rubbish or recycling at the lakeside campgrounds. Water and facilities are concentrated at Kerr Bay.

Nature and Wildlife

• You’re in honeydew beech country—learn about the forest ecology at the DOC centre.
• Eels are easily spotted around the jetties; trout inhabit both lakes. Sandflies can be fierce around still, shaded spots (especially near Lake Rotoroa).

Getting There

• About 90 km from Nelson via State Highway 6, turning onto Korere Tophouse Road to connect with SH63. About 103 km from Blenheim via SH63 along the Wairau Valley.

Best Time to Visit

• Quieter outside peak times: Christmas/New Year, powerboat/regatta weekends, and Easter book out fast. Weekdays and shoulder seasons feel mellow.
• For skiing, winter is prime; for hiking, biking, and boating, spring through autumn are reliable—just remember alpine weather can change fast.
