Kembang soka is only an hour driving to the west side of jogjakarta. U can go by bike or car. Renting bike in jogja is only 50k perday.
U need to do tracking a bit around 20minutes moreless, and then u can see the beautiful water scenery in kulonprogo,jogjakarta. For those who cant swim no need to worry, they provided tubes that u can rent also. There will be some local sellers that provide foods and hot drinks. Alcohol is allowed but u need to bring it by urself.
Why this place is a MUST seen place? Cz it will give u comfortable and peacefull feeling in the same time.
