I have never been on the island Langeland before, it's beautiful, I can highly recommend it.
We went to Skovsgård, an organic farm with family activities, we collected insects in a small pond in the park, and had lunch in MadMarked (FoodMarket). In the FoodMarket you can buy locally produced organic products.
After lunch we went to see the wild horses, a herd of approx. 60 Exmoor ponies who manage on their own all year round.
