Vale 194 - FLEURIEU PENINSULA
Nestled behind the main street of McLaren Vale, you’ll find the ultimate homebase for your next group wine tour. Vale 194 is the newest addition to the township of McLaren Vale, boasting five bluestone holiday homes in their very own neighbourhood. Under each roof you’ll find three bedrooms and two bathrooms, plus all of the creature comforts necessary for a stay in wine country. After a day spent sipping on McLaren Vale's very best drops, return to Vale 194 and soak up the serenity of this home away from home. Each cottage can accommodate six people, and the entire Vale 194 property can sleep 30.
