The Perfume pagoda (Chua Huong Tich in Vietnamese) lies 60km southwest of Hanoi. It is dedicated to Quan Am, the guardian spirit of mother and child, to whom childless couples pray. The pagoda is one of the many shrines built in the area in limestone caves, and is regarded as one of the most beautiful spots in Vietnam. It is a popular pilgrimage spot, particularly during March and April. The Perfume pagoda can be accessed by boat through the Yen river, followed by a climb along the mountains or a cable car trip.
