Meeting at the Chevron , Highway 79 in Florence. Stock vehicles not recommended, modifed suggested, as this is a difficult trail. This is a full day so plan accordingly.
There are two parts to this trail, getting to it (the section described here) and running it (see "Martinez Mine Loop"). Getting to it means traveling in normally through Box Canyon and the trail to the Martinez Cabins. The section to the cabins had changed a little due to some extra washouts and some rocks but it’s still not overly difficult. Unlocked trucks might have a little difficulty with getting cross axled in places but should make it through with care. The cabins are still there but the white one has half collapsed and the generator that used to be behind it has now been dragged some distance back to the rocky creek on the way in.
