Located in the North Western corner of Tsolyánu, the Átkolel Heights, are the most distinctive geographic feature of the area. The heights are the the remains of the cone of a gigantic volcano, dormant eons past. They are surrounded by steep cliffs on eastern, western and southern sides while in the north the feature slopes gently down to the surrounding landscape. The caldera of the volcano is now a lush valley with forests and lakes. The cliffs are largely inaccessible but for a cleft on the southern face known as Júmre's Ladder, a series of ledges that provide access of a sorts.
