unforgettable experience - We joined another family of 3 persons and went for a 8 hours, 15km private tour across the Muong Hoa Valley, lead by a nice Hmong lady. The experience was fantastic, a real adventure where we could see the great scenery of the rice terraced valley, learn and watch about the life of 3 different villages, populated by different ethnic groups (Black Hmong, Zay and Red Dao), eat delicious food, talk to several local and friendly people, walk across villages, rice paddies, bamboo forest, places plenty of life, traditions, history, culture and farm animals. We started from Y Linh Ho village, going down the valley, crossing the villages of Lao Chai, Tan Van and completing the tour after the village of Giang Ta Chai. When planning the tour we agreed about a kind of "one-way" trekking, so from Giang Ta Chai we had a taxi picking us up for the way back. The weather was variable, including some heavy rain, so overall it was not easy due to the fact that a part of the journey was on muddy lanes, made very slippery after the rain. Fortunately some nice local people was always available to help us in the most difficult passages. A must-do experience while in SAPA! My last consideration: hurry up! The wonders of this place are attracting more and more tourists, and this is opening the doors to excessive building construction and also spoiling of the native's culture.
