Prästens badkar (Priest’s bath) is a geological curiosity called a sand volcano formed about 500 million years ago. There are perhaps thousands of such sand volcanoes in the world. But what makes Prästens badkar special is that it is the only such known formation that is above sea level, so you can admire it without having to dive.
You can park your car in the nearby car park and Prästens badkar is about a 5-minute walk along the coast.
