Avenc de la Serp

It is a fissure opened in the conglomerates of the lower section of the Barranc de Cubars -Les Planes- due to the attraction of the small cliff and masked by years of clearing stones and branches from the almond grove existing there. The fissure is visible or can be guessed at along almost 100 metres from the outside, and lets us enter through two openings 45 metres apart, each with shafts of 5 m., with no interior connection. The maximum depth is reached with a steep slope after the shafts at 12 metres of depth.
