On the way from Henigou to Huanglong, we passed Songpan County and Chuanzhu Temple, avoiding the Huanglong Tunnel, and chose to turn over the mountain from the Liangyukou of the snow mountain to Huanglong. Although the mountain weather has changed so that it has to turn back and turn back to the tunnel to Huanglong, but overall, the experience of first exploring the secret of Huanglong is worth nostalgic, and the scenery is endless. Today, the "secret" of Huanglong in our eyes is actually the old road to Huanglong in the past - 120 county road, but since the tunnel repaired, this road up the mountain has been few people, why is the mining recommended to everyone here? There are three reasons, please look down. The road conditions are better than before after the Huanglong tunnel was built, the road is not only not abandoned, but also remodeled. At present, this road is a asphalt road, although the rain and snow season landslides, ice and other geological disasters are still inevitable, but if the weather is fine, driving on the road in good condition, the mood is comfortable. . The overall altitude of this road is high, and the layers are stacked with each other, the pine and green cypress are greeted, and the snow-capped mountains and white clouds are followed. It is indeed a road worth visiting. Traveling to Huanglong, it is a pity to miss this place when the weather is fine. After the Huanglong Tunnel was repaired by few tourists along the way, few tourists specially went around the mountain road to the scenic spot. So you can enjoy the beautiful scenery quietly along the way, and friends who like cold attractions must not miss it. However, on this road self-driving tour, there are also three noteworthy problems, also summarized as follows. Do not go to this road in rain and snow weather geological disasters are frequent, the actual experience of mining tells everyone: rain and snow weather is easy to cause landslides, there is snow and dark ice on the road, the driving process is very unsafe. Prevent high anti-high road altitude is higher, the highest point of the snow-capped mountain Liangyukou altitude reaches 4007 meters, friends (especially the first time on the plateau) must pay attention to bring oxygen cylinders or carry oxygen tablets to go. If there is altitude sickness, please slow down when you get off the bus and watch the scenery. Avoid running or talking loudly before adapting to the altitude. In addition, the temperature is higher and the altitude is lower, and warm clothes should be prepared in advance. .Pay attention to the road sign at the intersection to take this road, from Chuanzhu Temple to Huanglong direction has a intersection, left is "Huanglong", right is "Snow Mountain Liangliang", then please choose the right road, you can over the mountain through the snow mountain Liangliang mouth to Huanglong! Add a self-driving tour related matters: there is no gas station along the way, but the whole road is not long, you can add oil in advance and then go up the mountain.
