Enjoy for miles. A beautiful very long wide firm gravel road. Excellent access. Even with a normal city bike. Cycled several times, but it is not fast here in a muddy way. Solid gravel. There are some coarser stones in between, so that's why I prefer to do it with the cyclocrosser or gravel bike (MTB is of course also possible), than with the racing bike. Very nice road on the border with Germany. Reichswald on one side and open countryside and ponds (from the sand quarry) on the other. This road still has options for a continuation over more unpaved roads/paths in Germany.
