There are field trips or rambles at least twice a month on Friday or Saturday morning during the season (from mid-October to late April) to places of interest around Qatar. The trips are usually led by people who have some knowledge of a particular region or subject, e.g. amateur or professional geologists, botanists, archaeologists and so on. These activities vary from a couple of hours walk to a full day excursion. There are also camping trips and star-gazing expeditions from time to time. Children are welcome on the trips provided they are kept under parental control at all times.
