A kangaroo island campervan guide for the ferry-brave

Kangaroo Island starts with a boat. The vehicle ferry runs between Cape Jervis on the Fleurieu Peninsula and Penneshaw, taking about 45 minutes across Backstairs Passage. From Adelaide to Cape Jervis is roughly 108 km and 1 hour 45 minutes, but do not cut it fine; the road down the peninsula is scenic, bendy in parts, and not improved by a nervous driver watching the clock.

Book the campervan Kangaroo Island ferry space by vehicle length and height, especially in summer, school holidays and Easter. A 6 m campervan is a different booking beast to a little hatchback. Turn LPG bottles off for the crossing, follow crew directions, and keep snacks in the cab unless you enjoy unpacking a fridge on the wharf.

• Do: arrive early, with fuel, water and your ferry booking ready.
• Do not: assume you can roll up in January with a long motorhome and charm your way aboard.
• Before sailing: top up groceries and drinking water on the mainland if you are budget-minded.

Kangaroo Island is about 155 km long and up to 55 km wide, with sealed roads linking Penneshaw, American River, Kingscote, Parndana, Vivonne Bay and Flinders Chase National Park. The big-ticket route from Penneshaw to Remarkable Rocks is around 140 km and can take 2 hours before you stop for fuel, coffee, emus, or the inevitable argument about who saw the echidna first.

Many side roads are unsealed. Some are perfectly manageable in dry weather; others turn corrugated, dusty or greasy after rain. Check your hire conditions before taking a campervan or motorhome on dirt, because insurance exclusions are a very expensive way to collect a beach sunset. Night driving is the big no: kangaroos, tammar wallabies and possums treat dusk like peak hour.

• Fuel: plan around Penneshaw, Kingscote, Parndana and the western/south-coast supply points; do not arrive at half a tank and a hopeful grin.
• Range: allow at least 300 km of comfortable fuel range for a west-end day.
• Speed: sealed roads are often 80-110 km/h, but wildlife and gravel shoulders make slow and boring the winning style.

Kangaroo Island is not the place for making up your own free camp in a beach car park. Overnight stays are expected in designated campgrounds, caravan parks and approved sites. Council campgrounds are useful for self-contained vans, while powered holiday parks suit anyone wanting showers, laundry, a camp kitchen and a battery-saving night on 240V.

For camping near Kangaroo Island before or after the ferry, look around Cape Jervis or the Fleurieu Peninsula rather than trying to sprint from Adelaide in the dark. On the island, a tidy first-night plan is Brown Beach or Penneshaw if you arrive late, Kingscote or American River for services, and Vivonne Bay or the west end when you are chasing beaches and Flinders Chase.

• Book ahead: summer sites and powered bays can disappear quickly.
• Self-contained matters: carry your own toilet solution, grey-water plan and rubbish bags.
• Dump points: use official dump points in town areas or holiday parks; never bury waste or empty cassettes in bush toilets.

Flinders Chase National Park is the western headline: Remarkable Rocks, Admirals Arch, Cape du Couedic and huge ocean views that make a campervan feel like a lunchbox on wheels. Seal Bay Conservation Park, Kelly Hill Caves, Cape Willoughby and the north-coast beaches round out a proper motorhome Kangaroo Island route without needing a 4WD.

National park entry, tours and camping are generally booked online through South Australian parks systems, with basic campgrounds often around the $20-35 a night mark and attraction fees separate. Pets are not allowed in national parks, fires are restricted or banned in hotter months, and generators may be limited or unwelcome. Read the sign at the actual site; it beats arguing with a ranger in thongs.

• Do: visit Remarkable Rocks early or late for easier parking and better light.
• Do not: climb barriers, feed wildlife or park across bus and long-vehicle bays.
• Fire danger: summer days can push past 35°C, and total fire bans are not suggestions.

You can technically drive around Kangaroo Island in a couple of days. You can also technically eat cereal with a spanner. Four to six days is the sweet spot for most self-drivers: enough time to avoid constant backtracking, wait out a windy beach day, and still get to the west end without arriving frazzled.

A simple plan is night one near Penneshaw or Brown Beach, night two around Kingscote or American River, nights three and four near Vivonne Bay or Flinders Chase, then loop back via the north coast through Stokes Bay and Emu Bay. Keep the final night close to Penneshaw if your ferry is early; missing it is not a charming travel story when the next crossing is full.

• Best months: March-May and September-November for milder weather and fewer crowds.
• Winter: cooler, greener and windy, with nights often under 10°C.
• Summer: book earlier, carry extra water and avoid long walks in the middle of the day.
