I've seen Mishref park from the highway since it was built but never visited until today. It is really a great place for families. There are basketball courts, tennis courts, volleyball courts, soccer areas, exercise areas and playgrounds.
It seems to be sponsored/built by Wataniya which is a nice idea for a company to be involved with the public and support a place for healthy activities. The only negative was the pools of stagnant water which is a breeding ground for mosquitoes and the occasional wiff of sewer.
