Un percorso sicuramente unico che, partendo dal borgo di Sasso Pisano, conduce nel cuore delle manifestazioni naturali legate alla geotermia.<\/p>\n
Camminando su rocce arroventate dal vapore, si osservano i fenomeni idrotermali superficiali, caratteristici di quest’ambiente sin dalla notte dei tempi e si riescono realmente a percepire le forze della natura, vive e pulsanti.<\/p>\n
Le fumarole, le fontane bollenti, i cristalli di zolfo che crescono lentamente e le bizzarre concrezioni, svelano un mondo insolito e colorato: un ambiente simile ai paesaggi vulcanici, ma a suo modo inimitabile, ricco di alterazioni geologiche che hanno generato habitat del tutto particolari.<\/p>\n
Poche specie vegetali riescono a sopravvivere al calore o all’estrema acidit\u00e0 del suolo, tra queste il brugo (Calluna Vulgaris). Da segnalare anche l’abbondante presenza della Quercia da sughero, che qui prospera oltre i 600 m. di quota grazie allo specifico microclima.<\/p>\n
La zona ha rappresentato, per secoli, un autentico tesoro minerario, ambita e contesa per le molte risorse, tra cui Vetriolo, Allume, Caolino e Boro.
\nIl percorso sale fino a raggiungere una sella panoramica nel parco Naturalistico delle Biancane di Monterotondo M.mo, con spettacolari viste verso il mare, per poi tornare indietro e ridiscendere al Sasso attraverso antiche castagnete, di cui alcune ancora coltivate per la produzione dei
