Run by an English-Estonian couple from their farm outside the village of Kaarma, about 15km north of Kuressaare, GoodKaarma makes organic soaps from local ingredients such as juniper, pine and sea-buckthorn berries. If you’re interested in getting your hands dirty (or should that be clean), you can book into a 75-minute soap-making workshop (per person €10, minimum five people).
There's also a pretty garden terrace and cafe-bar, with homemade snacks, organic teas, local beers etc. Besides soap, the shop sells local arts and crafts.
