Putrajaya, 25-30mins drive from 1502a, you can visit several parks in a row. The parks are well designed and maintained, it is a nice and comfortable place for friends and family hanging out.
Putrajaya is a place which is biker friendly too, where you can cycle around or have a morning or evening jogging.
There is also a lake at the botanical park which is a very good sunset catching point. Grab some nice food and drink, have a picnic at the lakeside and enjoy the dusk! Or course! You can do it in the morning too!
