- Aquapark, at abudakha (swimming area with many types of entertainment pool)
- Katara (reclamation area, incl view, fine restaurants & sometimes local events)
- Souq Waqif, reinventing of traditional market, have several cafe, etc (at these time better go after sunset, and weekend it also great time if to greet the crowd) and for the food the best is Bandar Adn, yamani food.
- Malls (for now Landmark might be the only option, plays area, shopping, food &beverage)
- MIA.museum of Islam (actually not really interesting abt inside the museum, but it has a really great view restaurant, and there's also park with children play ground, & around 5 pm u can play a huge trampolines (around 20 QA if I not mistaken)
- sea side, maybe around inland, for desert skiing, swimming, fishing, offroad, etc
