Follow in the footsteps of the first tourists of St-Luc to discover the "Sémaphore Alpestre" at the top of the Rothorn de la Bella-Tola. The stop leading you to the panorama of the "Phare" imagined in 1866 by M. Griolet, will allow you to admire many 4000m. Return via the Bella-Tola point and the Pas de Boeuf pass.
