At Likas Bay. From downtown Kota Kinabalu, head north on the coastal highway for about 10-15 minutes. You will see the mosque to your right gleaming above a man-made lagoon.
Sprawling above a man-made lagoon at Likas Bay, the mosque was built as such that it created an impression to be floating above water. The architecture is marvelous, closely and immaculately resembles the design of Nabawi Mosque in Medina, Saudi Arabia. The sky-blue dome blends perfectly with its white masonry.
The mosque can fit in about 10,000 people. The view during sunset is magnificent. The golden hue from the setting sun glorifies its features. Added to that is a picture-perfect water reflection from the lagoon below. Simply breathtaking and worth your visit.
Probably one of the most spectacular place to see the sunset too.
Do visit to see the architecture. Nonetheless, please follow the local guidelines on visiting mosques for non-Muslims. There is nothing wrong if you are stopping by to admire the edifice and to take some photos.
