Itinerari situat a Maians, poble adscrit al municipi de Castellfollit del Boix, a la comarca del Bages. Té 10 seccions amb una llargada total de 1.470 metres, a una alçada mitjana de 534 metres. Els comptatges es van iniciar oficialment el 2024.
Tot el recorregut transcorre per ambients mediterranis continentals, sobretot per pinedes de pi blanc (Pinus halepensis) amb sotabosc de brolles calcícoles, formades per foixarda (Globularia alypum), romaní (Salvia rosmarinus), farigola (Thymus vulgaris), bruc d’hivern (Erica multiflora) i llentiscle (Pistacea lentiscus), o zones ruderals, habitualment amb camps de conreu a la vora. Malgrat això, també hi ha alguns espais oberts, amb diverses herbàcies: ravenissa blanca (Diplotaxis erucoides), Malva sp., ravenissa groga (Erucastrum nasturtiifolium), Veronica sp. i lletsó (Sonchus sp.), que fan la funció ecològica de prat malgrat acostumar a ser zones de camps de conreu abandonats. En algun punt trobem vegetació i estructures ecològiques més típiques de zones humides, com les bardisses amb esbarzers (Rubus sp.) i presència de Vinca.
