Park director Buncha Ramsiri said on Tuesday the free admission is meant to honour the Queen on what is also National Mother’s Day and encourage people to take an interest in nature and the conservation of natural resources.
The park is also a great place for families to relax and have some fun, he said.
Its popular attractions include the morning seas of fog that drift across high-altitude, flower-bedecked pastures when the temperature drops as low as 13 degrees Celsius.
