Dear friends,

As we approach the end of winter, local farmers prepare the soil trilling steep hills for corn planting. The planting of corn, an important crop in our indigenous culture, marks the beginning of the spring.

Local visitors crowd the sanctuaries during the weekends while visitors from North America, Europe and Asia, visit during the weekdays.
