If you are looking for a unique escape from everyday life, Agatha at Devon Valley Farm Stays is a stay you have to consider! I celebrated my 26th birthday here and all I can that is that this definitely a hidden gem in the Adelaide Hills. Nestled on a working farm, you will be welcomed to a waterfront stay in a clipper caravan with amazing views and an outdoor bath that makes the stay so dreamy. If you ask me to recommend when to go, I'd definitely say spring because with all the winter rains, the hills turn a lush green! It hosts only 2 people so it's perfect for a romantic getaway.
P.S. there's highland cows here too!!!
