There are five zones around Takamatsu Airport: Adventure Zone, Sky Zone, Grass Ski Zone, Port Hill Zone, and Country Zone.

The Port Hill Zone includes playground equipment for children, a water fountain, and a grassy area.
For grass skiing, there is a 200m natural grass slope and a sled slope for children.
For grass skiing, you can rent the equipment, but the shoes are over 20cm long and the equipment is heavier and more difficult to handle than skis, so it may be difficult for 1st and 2nd grade elementary school students, although it varies from person to person.
I think that 1st and 2nd grade elementary school students and kindergarten children can enjoy the sledding slopes.

Additionally, for infants and children in the lower grades of elementary school, Sanuki Kodomo no Kuni, located on the south side of the airport, is recommended as it has a wealth of play equipment and learning facilities.
