Although the road ends for civilians at the gate in front of the tunnel, the detour is definitely worth it. A few vertical meters accumulate along the way and the sights are worthwhile. With the road bike is either at the military gate and / or the Mirador finale. Ideal for integration into the Formentorstrecke.
It seems to me that the cordon would be brought forward. :( Didn't find it worth mentioning, especially compared to Formentor. Anyone who (like me today) hopes for the Coll de Baix or even the platja, as it is advertised by Komoot (in my opinion) as a racing bike tour, will be severely disappointed I turned around 1000m before the end of the track so as not to completely crush my rental racing bike. :(
