In several of the dune plantations in Thy - like in the National Park - it is possible to find marked riding trails. You can find the routes at the Forest and Nature Agency Thy or visit one of the tourist offices in Thy - we will be happy to help you out with maps and answer any of your questions.
In Thy you will find several tour guides with riding as a part of their program. The trips range from a short walk on the beach, swimming with the horses in the lakes or to longer rides over several days.
There are many opportunities - just throw yourself into it, and ride off into the sunset!
