Yen stream lasts about 4 kilometers; origins from a water-cave in Lo Rung Vai field, flows meanderingly through a swamp to Yen Vy village, Hoi Xa village, Duc Khe village and reaches Day River. The piece that flows through the swamp is covered by green mountains with a lot of natural mysteries. Many mountains were called by different names based on their shapes by ancient local residents: on the right hand side of Yen stream is Dragon mountain (Five Mountains)
in the opposite side is Deo (Slide) mountain, looking like a drunk; next is the Phoenix, in the opposite direction is Ly mountain (Lion mountain) which has victory statue praising local residents of Huong Son who were heroes in the wars fighting against French colony and American Empire.
Next is Ai Mountain, an other name for Turtle Mountain. Then we reach Phong Su (Monk’s rooms) Mountain that has rocky partitions separating each monk’s room. In the top of this one has two rocks in the shape of a monk and a female bonze. Walking on the opposite direction, we meet a bridge crossing Yen Stream, named Hoi Bridge. Hoi Bridge was made by ironwood in 1860 by local residents of Hoi Xa. The purpose of this was to create a way leading to the forest for farming purpose. After many repairs, it was made by concrete as we see today.
Next to Hoi Bridge is a small cave having four characters carved by Lord Trinh Sam “Son Thuy Huu Tinh” when he came to visit Perfume Pagoda in 1770. Then we reach Thong Dau then Doi Cheo Mountain (the ancient name is Python Mountain), which marks half of the waterway we have passed.
Visitors then reach Hang Ba (Female Cave) field, on the opposite direction is Ong (male) field that makes a romantic scene as a poem of Doctor of Philosophy Chu Manh Trinh “A piece of Male Field touches the back of the Female Mountain”. There’s a famous legendary hero closely related to Female Cave in this area “Once upon a time, there was a beautiful widow who had lost her husband when she was just a young lady. She suffered the poverty and took care of her mother-in-law to keep the moral standards. Day by day, she rowed and steered the boat around the cave to seek for firewood, jam and vegetables, sold and served her mother. One day, the flood suddenly came, the boat sunk and she die. Feeling sorry for a young grateful daughter-in-law, posterity called that cave “Female Cave” to commemorate the unfortunate lady.
The itinerary continues with Ba Dai Ruou (Three Wine Bottles), Chicken, and Elephant Mountain. This mountain closely related to a strange legendary hero “Huong Tich has one hundred mountains in which 99 ones turn to Huong Tich Pagoda to show their admiration. The only one that turns to opposite direction was punished by genie that it lost a vast piece at bottom and bended knee".
Next to Bended Knee Elephants is Mam Xoi (steamed sticky rice) Mountain.
