Sans utiliser de t\u00e9l\u00e9cabine, il faut emprunter depuis Plan-Mayens, en-dessus de Crans-sur-Sierre, le bisse du Ro. Attention au vertige! A la sortie du bisse, se diriger en direction du Col de Porchet.<\/p>\n
La source du Ro (603’300\/133’500 alt. 2170m), visible depuis le chemin, se situe \u00e0 droite d’un cirque de falaises. La grotte peut aussi \u00eatre atteinte en montant en t\u00e9l\u00e9cabine \u00e0 Cry-d’Er ou a la Bella Lui.<\/p>\n
La source du Ro \u00e9tait certainement l’alimentation en eau principale du bisse du m\u00eame nom lors des p\u00e9riodes d’\u00e9tiage. Cette eau provient de la fonte des neiges, vu le d\u00e9bit lors de la visite en \u00e9t\u00e9 (p\u00e9riode s\u00e8che).<\/p>\n
Cette source sort d’une grotte ais\u00e9ment p\u00e9n\u00e9trable avec un profil inclin\u00e9 elliptique typique. Malheureusement, la section diminue apr\u00e8s une dizaine de m\u00e8tres. Toutefois, la suite serait peut-\u00eatre p\u00e9n\u00e9trable avec un mat\u00e9riel ad\u00e9quat de sp\u00e9l\u00e9o et non celui de montagne…
