It's great that this park exists despite its quieter location in the Allgäu region. I hope this will be appreciated by appropriate use. I'm 62, so don't ask me how interesting or difficult it really is. Compared to the popular bike park in Eschach, which will be partially paved by 2024, it looks quite decent.

The end of the trail once again shows its teeth at this point of the highlight. Quite steep, YES. Rooty, YES. Best only when it's dry. Otherwise, most people will probably have to push their bikes.

Very nice view of the Sonneckgrat. With good visibility up to the Nagelfluhkette.

The ridge path allows little prospects - all the better when it works like here on the Sonneneck summit cross!

The marked piece is definitely not suitable for beginners. Technical ability is a requirement! If you can do it technically, it's a lot of fun ;)
