Yes, I know that very well.
The following applies to the area between the Trendelburg country road (stone number 83) - Manrode and Eselsberg (south of Mudddenhagen (stone number 100): there are still 14 stones, 11 of which are original stones from 1754. It is important to know that wind breaks and their consequences meanwhile the search and Observing a number of stones (strong) make it difficult!!! You can only get to individual stones with rose scissors (blackberries!).Former forest paths/border hiking trail(s) are littered with branches, some 'crown wood'.At every visit I try to separate individual areas a bit to make it more accessible, but only a chainsaw would help in some places... But it is possible.
The striking 'Hoher Berg' is really worth a 'detour', but as far as I know not just on the shortest route from e.g. Stein 88 (formerly a border crossing point with road/customs payment: "Sieler Klappe"), but preferably from the meantime Furnished parking lot: from Muddenhagen/ outskirts towards Manrode seen from third paved dirt road right to the forest. There is also hiking trail information on higher-level hiking trails such as e.g. Fulda-Diemelweg. Coming from Manrode in the direction of Muddenhagen, after the access road to the 'Hohen Berg' and down the valley to Muddenhagen, it would be the first paved dirt road on the left, shortly after a busy dirt road coming from the Bühner direction leads to the Manrode - Muddenhagen connection.
There is also a large hiking car park between Trendelburg and Manrode in the 'Deiselberg' forest area, where you can (still, as of 03/15/2023) find a large, fallen hiking sign for the entire forest area. There is also a 'rescue point'. The 7 wind turbines in the entire western forest area of the Deiselberg may emotionally limit the desire to wander, on the other hand there are very well paved paths, some of which are part of the hiking trail network. Trail signs (painted on tree trunks and fading) in the forest are sparse.
