This should be one of the tourist attractions in Doha but definitely not in this kind of temperature though - a bit cold to hang around the beach. That should be a good sign for people running away from their busy lifestyle. We were there at about 4:00 p.m. and dusk was already approaching. Remember in winter, daylight is shorter than night. However, the scene was absolutely beautiful and I would not mind sitting there looking at the sea for hours (if the weather is good, that is).
The do's and dont's - mostly dont's. Good news, there will be SPOT THE ERROR section for you, taken from this sign board later.
The whole place looked quite new to me. Nevertheless, the scene would definitely be merrier in summer, no doubt. I will come back to Doha during another season next time then.
