Dutch Mountain Trail Application form With this form, you choose one of the Dutch Mountain Trail group arrangements of Natuurvrienden Eikhold. You are then bound to the days in which these are organised, and the number of places is limited. You can also choose to walk the trails without a guide. In that case, just book your stay at Eikhold and buy the hiking guide and additional information (€20) separately. Due to the large number of applications for the DMT, registration is temporarily not possible, To keep the waiting list from getting too big.
