The red stone beach in the two estuaries of Yajiayu is one of the largest red stone beaches in the world. The rust-red substance growing on the stone is a rare algae (lichen complex), under the conditions of humidity, temperature and climate. This plant will grow naturally on the surface of the rock, die in about four or five years, and then regenerate. Yajia Terrier's red stone is one of the rarest species that nature has given to Gongga Mountain. The scenic area of Ganzi Prefecture is too large, and it is recommended to drive by car if conditions are available. From Chengdu, take Chengya and Yaxi Expressway to asbestos, go up S211 Provincial Road to Moxi Town and then follow the Momo Road to Yajia Terrier; or take Chengya Expressway from Chengdu, transfer G318 National Road to Gangudi and follow the S211 Provincial Road to Moxi Town and then take the Momo Road; At present, there is no direct public transportation in Yajia Terrier Scenic Area. You can choose to charter a car in Kangding or Moxi Town, about 200 yuan. A tour trail and observation deck have been built on the roadside where Hongshi is most concentrated, and you can watch and shoot Hongshi up close. The best shooting location here is in the red stone forest of Sun Yu and Deng Chao Station in the "Painting Wall". Standing in it, it seems that you can feel the magic of nature. Try to choose the best time at noon, and the visibility is relatively high; You can also watch the sunset at the Red Rock Beach Observation Deck, with rows of snow-capped mountains on the top, five-color forest sea in the middle, and a red rock beach on the bottom, which is very spectacular.
