Itinerari de 1.417 metres de longitud total, amb 10 seccions, en ple espai protegit del massís del Montgrí, al Baix Empordà. Té una alçada mitjana de 42 metres i s’ha mostrejat des de l’any 2015.
Es tracta d'una zona calcària i amb fort eixut estival. El recorregut travessa camps d'oliveres, fenassars, llistonars, prats sabanoides d'albellatge, timonedes i altre matollar baix. En canvi, pràcticament no inclou zones arbrades, malgrat que el garric hi apareix puntualment i és molt abundant al voltant.
