Though the idea of going down to the dark tunnel through the mountainous tunnel, the idea of the tunnel is not something but the idea of the tunnel is nothing. The main attraction of the Alutila center is its 'mysterious tunnel'. In the local language, "Matai Haqor", which means Bengali meaning Dehuagha. The position of this mysterious tunnel, built on the footpath of 266 stairs on the top of the hill, lies in the foothills of the Alutila hills on the stone and rock clay. 
The cave diameter is about 18 feet and the length is about 280 feet. The entrance and the end is covered with light and darkness. In the middle of the dark dark dark, the fountain of cold water flows beneath the cave. Entering the cave with a feeling of grief is like being fearless and thrilling on the one hand. Not only in Bangladesh but also in other countries of the world, there is no such precedent for such a natural tunnel path. Unique in the cave can not be accessed without torch or bright torch light. The torch tourism center is available for 10 taka. Going on one side of the cave and going out on the other side takes only 15/20 minutes. The main tourist attraction of this tunnel is the only natural tunnel in the subcontinent.
