Even before Klang became the capital of Selangor, Kuala Selangor was the home of the Selangor Sultanate. Two fortresses were built on the hills overlooking the estuary of the Selangor river in order to guard the city. The larger of the two, standing on Bukit Melawati, is now the royal mausoleum containing the remains of Selangor's early Bugis rulers.

Bukit Melawati overlooks the Kuala Selangor Nature Park, which is being jointly developed by the State Government and Malaysian Nature Society. It consist of more than 250 hectares of coastal land, most of it mangrove swamps, and contains about 156 species of birds. An estimated 100,000 wading birds, comprising 30 odd species, pass through here on their annual migration. Artificial lakes have been created to attract some of these birds and observation hides have been built to allow visitors to watch the birds without disturbing them. Leaf monkeys can also be seen in the mangroves. A visitors' Centre with information and educational displays is located on Bukit Melawati, and a path leads from there to the park.

Kuala Selangor can be reached by buses from Klang and from the Pudu Raya bus terminal in Kuala Lumpur.
