Location

By the BV-4031 road from Castellar de n'Hug, shortly after kilometre 21 we reach the coll de la Creueta, where we turn left onto a track heading to the Pla de Rus and the coll de la Bassa; before reaching it, and when the track levels out, we find ourselves a little over a hundred metres of elevation difference below the summit of Pla Baguet. This elevation difference must be climbed up to the summit; the cavity is located at the E end of the summit.

Entrances

Description

Morphology

A strong absorption form, with a relatively large entrance that opens at the bottom of a surprising rocky depression, formed from the joints running NW-SE. After the initial ramp, a narrow passage that had to be cleared gives access to two opposing ramps that end impenetrably.

History

Explored and surveyed in 1978 by the GE Badalona, although it was not published until the appearance of the third volume of the Catàleg Espeleològic de Catalunya in 2009.

According to the first explorers, the name of the cavity refers to the name of the summit where it is found, cim del Tarter, but according to the Nomenclàtor de toponímia major de Catalunya, this is none other than the cim de Pla de Baguet; the ICGC also calls it this.

Nil Hosta and Tanit Sanmartin located and explored it again in July 2026.
