There is a lovely stretch of coastline on the outskirts of Al Wakrah. The water is quite shallow, so you'll have to wade out a fare way if you want to swim. Or, if you have a four-wheel drive you can do as the locals and drive it out to a sandbar and jump straight in (see photo)! But, if you're concerned about damaging plant and animal life, park your car and walk instead of driving straight onto the beach.
In addition to the sea, there are also several shallow khors (creeks) that run out to the ocean. These are filled with mangroves and attract a fair bit of bird life. Apparently flamingoes are common in the shallow waters in the winter, but we didn't see any when we were there in April.
There is a fort on the right side of the highway coming from Doha. I believe this is technically part of Al Wukair, but it's just across the street from Al Wakrah. The doors and windows are bricked up, so it doesn't appear to be in use. There is alot of construction going on around it at the moment, so perhaps it will be restored. The mosque next door is quite attractive.
There are a few examples of various traditional architectural styles in Al Wakrah. I believe the third building pictured here is the city museum, though there was no sign indicating that's what it was. It was certainly shut when we were there.
The harbour is filled with wooden fishing dhows, and you can watch the crew members preparing for the next trip out. If you time your visit right, you may be able to see the catch of the day being brought to shore. Most of the fishermen are expat workers from South Asia.
