In my 2 weeks in Sweden, this was the most interesting WH site I have come across. The landscape of the Stora Alvaret is unique and fascinating, like nothing I had ever seen before. A barren limestone plateau, it covers the southern half of Öland and combines many historic sites with unique natural features (I think it should be a mixed WH site). Driving or cycling is probably the best way to explore Öland, but public transport is also an option. I took the bus from Kalmar (a great city by the way, with a fantastic castle and a nice old town) across the impressive Öland Bridge to the pretty port of Färjestaden. From there I went to Eketorp, an interesting Iron Age fortification that is today a major tourist attraction. Next I went to the Ottenby Nature Reserve on the southern tip of the island, which features a wide range of habitats for migrating birds - and I also climbed Scandinavia's tallest lighthouse there. I thought this was the most interesting place I saw on Öland. Taking the bus is a bit complicated, because even in summer, they don't run very often, but with a bit of planning, it works out fine, and many interesting landscape features can be admired just as easily from the bus.
