Muara Harbor, located in Muara, Brunei-Muara District, serves as Brunei's primary commercial port and naval base. This vital hub for trade and logistics includes container terminals, bulk cargo facilities, and the Muara Export Zone (MEZ), a designated free trade area. Completed in 1973, the harbor has undergone expansions to accommodate growing cargo volumes.

While Muara Harbor primarily focuses on industrial activities, the surrounding area offers opportunities for relaxation and exploration. Serasa Beach and Muara Beach provide sandy shores for picnics and swimming. Wasai Bedanu Recreational Park offers hiking trails and scenic views, while Pelumpong Island, accessible by boat, invites visitors to enjoy fishing and island exploration.

For shopping, the vibrant Gadong Night Market offers a diverse range of street food, clothing, and local products. The Yayasan Sultan Haji Hassanal Bolkiah Complex and Times Square Shopping Centre provide modern shopping experiences with a variety of retail stores and dining options. Muara Harbor itself offers a quieter atmosphere, perfect for a relaxed evening stroll or enjoying the local eateries.
