The sulphur baths in Tbilisi are world-famous, in fact the whole city was built on top of thermal springs, with hot water reaching up to 40-50 degrees. There are different baths with different prices, from the cheaper shower rooms to the more expensive private rooms with sauna and massage.

For something a bit different, try ambling through the woodlands and grassy areas of The Hague with Dave, who will let you know which plants you can and can’t eat, as well as which of them have medicinal properties. The tour operates fairly infrequently but if you can book a spot well ahead of time it is a nice addition to any itinerary.

This giant panoramic work of art spans forty metres in circumference and reaches fourteen metres in height, capturing the small fishing village of Scheveningen as it was in the late nineteenth century in a cyclorama. It creates the illusion that the observer is atop a large sand dune looking down upon the village, an illusion which is complemented by the foreground within the artwork that is made up of artificial terrain. The museum is dedicated to the single work of art from Hendrik Willem Mesdag and there are lots of ways to experience it including a guided tour, lectures and even children’s treasure hunts.

Be prepared to have your mind bent, blown and rewired as you walk into the Lange Voorhout Palace where the illusory work of famous graphic artist M.C. Escher is exhibited. The palace is home to such legendary Escher paintings as 'Air and Water' in which birds are blended into fish and 'Waterfall' in which water appears to flow upwards instead of down. There are interactive experiences on the second floor, dedicated to the Eye of Escher where guests are encouraged to solve some of Escher’s most perplexing mysteries, including the impossible Penrose Triangle. On the third floor, there is a large-scale optical illusion where adults can appear to be children and vice versa. Audio tours and guided tours are available and there are additional temporary exhibitions taking place on occasion.
