Itinerary
5 Days: Limestone Coast & Coonawarra Itinerary
Mount Gambier is the gateway to this trip, not a drive-through town — it sits on a dormant volcano, and the Blue Lake, which turns a striking cobalt blue every November through March before fading to grey-blue for the rest of the year, is one of the more genuinely unusual natural sights in South Australia. Budget a proper first day here rather than treating it as a fuel stop.
- Length
- 5 days
- Total distance
- ~350 km round trip from Mount Gambier
- Season
- Year-round, though the coast is genuinely windier and cooler than Adelaide or Melbourne at any time of year — pack layers regardless of season. October–April gives the most reliable weather for the sinkholes and coastal walks; the region is noticeably quieter and cheaper outside the December–January peak.
- Vehicle
- Any 2WD. Mount Gambier is the practical gateway — about 4h30m from Adelaide via the Dukes Highway, or roughly 4h from Melbourne via the Princes Highway and the South Australian border — so most visitors either fly into Mount Gambier Airport or treat this as the final leg of a longer Adelaide or Melbourne road trip rather than a standalone flight-in destination.

Route map
Approximate route: Mount Gambier → Penola → Robe. Shown for planning only — this is not a turn-by-turn route. Always check current road conditions before you travel.
Route stops in order: 1. Mount Gambier, 2. Penola, 3. Robe.
The shape of this trip is coast-and-caves, then wine, then coast again: Mount Gambier's volcanic lakes and sinkholes, inland to Coonawarra and Penola for South Australia's best-known cabernet sauvignon country, then back to the coast at Robe or Beachport for the last two days. It deliberately doesn't try to cover the whole Limestone Coast in five days — Naracoorte Caves and the Coorong further north are both worth a separate trip.
Coonawarra is a genuine wine region, not a wine theme park — a handful of cellar doors along a short, flat strip of terra rossa soil, easily done by bike if your group isn't drinking, or with a driver or non-drinking driver if you are. Treat it as a single relaxed day, not a multi-day wine-touring itinerary.
Day by day
| Days | Route | Distance | Drive | What you do | Sleep |
|---|---|---|---|---|---|
| Day 1 | Arrive Mount Gambier | — | — | Settle in. The Blue Lake lookout and the Crater Lakes walking track are an easy first afternoon, and the Cave Garden — a sinkhole in the middle of the CBD, lit at night — is a five-minute walk from the main street. | Mount Gambier |
| Day 2 | Mount Gambier sinkholes & caves | ~40 km local | ~1h total | Engelbrecht Cave, a flooded sinkhole cave system with tours and platforms right in town, and Little Blue Lake, a swimmable, startlingly blue sinkhole a short drive out — genuinely one of the more unusual swimming spots in the state. Umpherston Sinkhole's sunken garden, floodlit after dark, is a short evening stop. | Mount Gambier |
| Day 3 | Mount Gambier → Coonawarra & Penola | ~50 km | 40m | A relaxed cellar-door day along the Coonawarra strip — arrange a driver or tour if you're tasting seriously, since the wineries sit close together along a single road and self-driving between them doesn't mix with proper tasting. Penola's Mary MacKillop heritage sites are a lower-key alternative if wine isn't the priority for everyone in the group. | Penola or Coonawarra |
| Day 4 | Coonawarra → Robe | ~90 km | 1h | A historic seaside town with colonial-era stone buildings, a working fishing harbour and long ocean beaches. Little Dip Conservation Park, just south of town, has coastal walks and freshwater lakes among the dunes — a good half-day if the weather's kind. | Robe |
| Day 5 | Robe → onward | varies | varies | Depart. Robe sits roughly 3h30m from Adelaide via Kingston SE and Meningie, or continue on toward Victoria and the Great Ocean Road region via the border if you're extending the trip rather than returning. | — |
Cost and booking notes
- Cellar door tastings in Coonawarra are commonly $10–$20 and often waived on purchase, similar to South Australia's better-known wine regions.
- Engelbrecht Cave and Umpherston Sinkhole both charge modest entry fees; the Blue Lake lookout and Cave Garden are free.
- Robe accommodation books out well ahead over summer and long weekends, particularly the Christmas–January peak — reserve early if travelling then.
