I do not think this trail is fun with a hardtail. Who said that the gravel road drove in parallel. Please do not overdo it. Many rely on such reviews. I was out of the trail for exploration today. He already has it in some passages.
S2 trail. Almost exclusively roots (almost always leads through the forest). Couple of nice bridges, very, very demanding. Absolutely not for complete beginners or people who say "oh, let's have a look".
