Kerr Bay camping, Lake Rotoiti: facilities, booking and what to expect

Kerr Bay camping on the shore of Lake Rotoiti is the main way to sleep inside Nelson Lakes National Park without carrying a tent up a valley. The Department of Conservation (DOC) runs Kerr Bay Campsite beside the lake, in beech forest, just off State Highway 63 near the village of St Arnaud in the Tasman region at the top of the South Island. It takes tents, campervans and powered caravans, and it is a booking-only site all year, which is the single most important thing to know before you set out.

What is Kerr Bay Campsite?

Kerr Bay is a DOC campsite on Kerr Bay Road, about 500 metres from the St Arnaud village shop. Lake Rotoiti is a substantial mountain lake with a maximum depth of 82 metres, fed by the Travers River and drained by the Buller River. The name Rotoiti translates as “little lake”. Trout were introduced to the lake, so it draws anglers as well as sailors and kayakers.

The national park around it covers roughly 1,000 square kilometres and was established in 1956. Its peaks rise past 2,000 metres, which is why the weather at the lake can change quickly even when the campsite itself feels sheltered. St Arnaud sits at about 650 metres above sea level, so nights are cooler than most people expect from a lakeside camp.

How do you get to Kerr Bay Campsite?

St Arnaud is the gateway to the park. DOC gives the drive as about one hour 30 minutes from either Nelson or Blenheim, and other sources describe it as roughly 90 to 100 kilometres from Nelson. Kerr Bay Road turns off State Highway 63 at the village, so there is no unsealed approach to plan for.

DOC states the campsite is not suitable for vehicles longer than 7 metres. That rules out large motorhomes and long caravan combinations, so measure the whole rig including the drawbar and any bike carrier before you book. A daily shuttle bus runs along State Highway 63 between St Arnaud and Nelson, Murchison, Greymouth, Blenheim, Westport and Picton, which makes arriving without a vehicle realistic for walkers and cyclists.

Do you need to book Kerr Bay Campsite?

Yes. DOC states that bookings are required all year, and that if the online system shows no availability the campsite is fully booked. No spaces are held for people who turn up without a booking. Your booking is for a site, and DOC allocates or lets you select it on arrival.

Bookings were open for stays up to 30 June 2027 when this guide was researched. Same-day online bookings are accepted until 8 pm if spaces remain, but do not rely on that in busy periods. DOC advises booking early for Christmas, the classic boat show and powerboat regatta weekends, and Easter. A phone or in-person booking through a visitor centre carries a service fee, so book online where you can.

DOC also states that the Campsite Pass cannot be used from 19 October to 30 April inclusive, and that Te Araroa walkers need the Te Araroa Trail Pass. Fees apply to stays here and vary by season and site type, so check the DOC booking page for the current rates rather than relying on an older listing.

What are the sites like?

DOC splits the campsite into zones named after native birds. The Bellbird, Fantail, Robin and Tui zones are powered sites with hardened surfaces. Kaka is a grassy tent zone. The Kiwi sites suit campervans and have a gravel surface with some grass. Non-powered sites are also offered.

In practice that means a tent camper should look at Kaka, a caravan or camper trailer that needs power should look at the four powered zones, and a self-contained campervan should look at the Kiwi sites. Because the site is allocated or chosen on arrival, tell the booking system the real size of your set-up. The 5 kilometre per hour speed limit applies throughout the camping areas, which keeps the loops calm for children.

Does Kerr Bay have showers and toilets?

Yes. DOC lists toilets in the ablution block, including a full-access shower and toilet. Showers are hot and token-operated. Tokens come from the camp host when one is on site, or from the DOC Visitor Centre during its opening hours, so collect tokens when you check in rather than at the end of the day.

A day shelter has cooking facilities, but no pots, pans or cutlery, so bring your own. There is a washing machine and clothes dryer, and a dump station opposite the cooking shelter. DOC does not state a drinking water arrangement or a generator rule on the campsite page, so ask the Visitor Centre and keep generator use considerate given the quiet-hours rule.

Is Kerr Bay Campsite dog friendly?

No. DOC states that domestic pets, including dogs, are not allowed at the campsite, and the wider Nelson Lakes National Park page also says no dogs.

Rules to know before you arrive

DOC lists these rules for Kerr Bay:

• No fires of any kind. Bring a gas stove for cooking.
• A 5 kilometre per hour speed limit in camping areas.
• Quiet from 10 pm, with no loud noise after that time.
• Sites must be vacated by 10 am on the day you leave.
• No jet skis on the lake.
• No drone flying without a permit.
• Park by-laws apply, and management can cancel a stay for rule breaches without refunding fees paid in advance.

Rubbish is a planning item rather than a footnote. The park runs pack-in, pack-out, and Kerr Bay has no rubbish or recycling facilities. DOC names the nearest waste transfer stations as Murchison, Richmond and Blenheim, so carry sealed bags and plan where the waste goes on the way out.

When is the best time to camp at Kerr Bay?

The campsite is open all year, so the choice is about weather and crowds. The figures below are St Arnaud climate normals for 1980 to 2012 from Wikipedia, and they show a real altitude effect: frost is normal from autumn to early spring, and the mean minimum drops below freezing in the middle of winter.

Season	Months	Typical range	What to expect
Summer	Dec to Feb	7.5 to 21.1 degrees	Warmest weather, busiest period, book early
Autumn	Mar to May	1.8 to 18.6 degrees	Cooling fast, frosty mornings by May
Winter	Jun to Aug	minus 1.6 to 10.0 degrees	Sub-zero nights, a heated or well-rated sleeping system needed
Spring	Sep to Nov	1.4 to 16.8 degrees	Cool and changeable, quieter than summer

Rainfall averages about 1,550 millimetres a year with no dry season, so wet gear belongs in the car in every month. DOC and Wikipedia both note that snow and poor weather can occur at any time of year in the park. The recorded extremes at St Arnaud range from about minus 10.6 to 31.4 degrees. Peak booking pressure falls on Christmas, Easter and the boat show and regatta weekends.

What is there to do near Kerr Bay?

The lake is the centre of the camp. A boat launching ramp is close to the campsite, and the area is used for fishing, kayaking and sailing. The Honeydew Track, a short loop of around half an hour, starts near the east jetty according to a tourism site; confirm the details with DOC before you rely on it.

The village has a DOC Visitor Centre that offers walk and tramping information, maps, hut bookings, fishing licences and interpretive displays. A water taxi runs from a jetty at the northern end of the lake, which opens up the far shore for walkers. Wikipedia lists the Lake Rotoiti circuit, the St Arnaud Range and Mount Robert as day-walk options, with the Travers-Sabine Circuit as the best-known long route. Robert Ridge, the route to Angelus Hut, is described as one of the more dangerous routes in bad weather, so treat it as a fine-weather objective only.

Wildlife and safety

The park is home to South Island robin, kaka, kereru, kakariki and whio (blue duck), and kaka have benefited from stoat trapping around Lake Rotoiti. Great spotted kiwi are mentioned as possible in the Rotoiti Mainland Island predator-control area, though sightings should never be expected.

The practical hazards are weather and cold. Mountain conditions can turn without warning, tracks to Angelus Hut are often snowy and icy in winter, and a lake this deep and cold deserves a lifejacket and respect.

What supplies are nearby?

St Arnaud has a village store with postal services, a petrol station, a cafe-restaurant, and the DOC Visitor Centre, all close to the campsite. The village has no reticulated fresh water supply, which is a reminder to keep your own bottles topped up. For a bigger shop, fuel stock-up or waste disposal, plan on Nelson, Blenheim or Murchison, which are the towns DOC names for waste transfer or which sit on State Highway 63.

One night or a weekend at Kerr Bay

For one night, arrive early enough to collect shower tokens at the Visitor Centre, pitch, and walk to the lake while the light is still good. Cook in the day shelter or on your own gas stove, watch the birds around camp, and leave your food packed away. Next morning, vacate by 10 am, then spend the rest of the day on a short lakeside walk or at the village cafe before the drive home.

For a weekend, use day one for the lake: a paddle or a fishing session if you have the licence, plus the Honeydew Track. Use day two for a bigger walk chosen with Visitor Centre advice, such as a section of the Lake Rotoiti circuit if conditions are good.

Who is Kerr Bay suited to, and who should go elsewhere?

Kerr Bay suits tent campers, campervan owners under 7 metres and caravanners who want power, hot showers and a kitchen shelter in a forest setting next to a lake. It is also a sensible base for walkers using the national park.

Look elsewhere if you have a dog, a rig longer than 7 metres, want an open fire, or would like to turn up without a booking. West Bay Campsite is the DOC alternative on the same lake, about 3 kilometres by road from St Arnaud on Mt Robert Road. It has no power, is open only from 27 November to 30 April, and has the same rules on pets and fires, so it suits a simpler tent stay in summer. If you want a stay with rooms rather than a tent, St Arnaud also has motels and chalets.

Planning checklist

• Confirm your vehicle and trailer total under 7 metres.
• Book online through DOC and note your zone type.
• Pack a gas stove, since fires are not allowed.
• Bring pots, pans, cutlery and a torch, because the day shelter supplies none.
• Pack warm layers and a sleeping system for sub-zero nights outside summer.
• Carry sealed rubbish bags and plan the disposal stop.
• Buy groceries and fuel before arriving.
• Leave the dog at home.

Common mistakes

Turning up without a booking is the big one, because no spaces are held for walk-ins. The second is underestimating the cold: St Arnaud is at altitude and frost is common outside summer. The third is assuming a bin will be nearby when Kerr Bay has none.

Plan it in the app

Save the camp on your route in MotoRidez and the planner shows road closures along the way, and where your tank runs out once you have entered the range of your vehicle. Save the route for offline use before you lose signal: it saves the corridor around your route, not a whole region.

Details come from the operator’s own records and pages, read on 20 October 2026, and change. We do not show prices or availability. Confirm fees, bookings, closures and fire rules with the operator before you go.
