Qatar is small enough to see from a single base in Doha: the Museum of Islamic Art on the corniche, the reconstructed Souq Waqif, the National Museum, and desert excursions to the inland sea an hour or so south.
The guides on this page cover Qatar as a whole. The comfortable season runs November to March; summer heat and humidity make outdoor activity impractical. Stopover programmes tied to the national airline make short visits common, and the metro covers most points of interest in the capital. Dress expectations in public places are more conservative than the modern skyline suggests.
