Approach
Just past the obvious fenced mine area (Minas de Mazzarassa) on obvious track on the right, before the start of the switchbacks ascending to Pozo Castillo, leads along the east hand side of the Pozo de Andara (Lake Depression) . The track splits, with the left hand route leading to an obvious small spoil heap containing the entrance to Segura 2. Continuing on the main track (over spoil heap obscuring track) leads to the Segura 1 entrance

Entrance
Segura 1 is obvious mine adit,

Description
The driven mine adit is 2m x 2m and continues straight for 20m in ankle deep water. The adit ends at a large platform (with old winch in place) part way up the FT16 entrance pitch. The left-hand side of the platform should be avoided as it is suspended by dubious old wood covered with rocks, that gives the impression of a solid floor! There is a small ascending passage on the right that leads to a window overlooking the main FT16 entrance shaft.
