Source Bleue du Bial
Known locally as the Source Bleue, this exsurgence opens on the left bank of the Célé 130 m downstream of the Sainte-Eulalie bridge, at the end of the small Bial stream. A 7 × 9 m cave mouth leads to a pool; sump 1 is about 75 m long at -6 m and sump 2 was explored for 170 m to -15 m in 1989. The cave totals about 545 m.
