To get to the mouth of the cave, one has to hike for 1.5 kilometers and cross the same river seven times (7X). Why, you might ask, must anyone cross the same river 7x? That is because in some parts, the edge of the river would be rocks and boulders you can not walk on, and so you must cross. Repeat this scenario as many times and you end up crossing the river 7x. Alas, I thought it was more than 7, and the guide said they were not counting just getting wet walking in the river, on its sides. Just crossing from one side to the other is 7x.
