It can be accessed from both l'Estartit and l'Escala, bearing in mind that during the summer months vehicle access is prohibited. Probably the most suitable access is via Sobrestany and the Torre Ferrana; from there we follow the Muntanya Gran road (despite the name it is a track but in good condition), we will soon find a fork where we follow the left; past the Roc Ferran viewpoint a long straight begins; after covering 2.65 kilometres from the Torre Ferrana, we will find on the right of the track a wide parking area (ETRS89 coordinates 513072 – 4658371).

From here and on the other side of the track a faint path starts in direction N30W which at 65 metres and on the right of the path leads us to the Cau dels Ossos Sud; the Cau dels Ossos Nord is 16 metres to the NE of this.
