Sights to See
Because my main purpose for traveling to Oman is work, I only had one weekend to go around. Well, technically I had two weekends--the first one was when I arrived in Muscat. During that first weekend, I was able to go one of Muscat's marketplace, thanks to a colleague who has rented a car for the duration of his stay. During the second weekend however, most of my colleagues flew out of the country, so I was left to tour on my own.
Mutrah Souq (or Muttrah Souk) is considered as one of the oldest marketplaces in the Arab world. It is located near the Muscat harbor, which was originally used to trade goods from India and from China [Source: Wiki]. Nowadays the main corridors of the marketplace contain stalls that sell souvenirs, fankincese, textiles, jewelries, and other dried goods for both locals and tourists alike.
THE CHALLENGES OF BEING A SOLO TRAVELER IN OMAN
While there are a lot of places to see in and around Muscat, most of the places aren't accessible by public transport. You would either have to rent a car (or a 4x4 if you're headed out to rough terrain), or avail a tour package from one of the tour companies in the city. I don't drive (and if I do, I wouldn't venture out into such strange territory alone), so renting a car is out of the question.
