Take a stroll in this magnificent ‘Kaiyusschiki-style’ garden and marvel at the various landscapes which unfold before your eyes. No-one would expect this oasis of tranquillity and contemplation so near to the sea and Oostende’s vibrant city centre. During Belgian school holidays (with the exception of the Christmas and the spring break holidays), open every day.

A former Belgian merchant marine training ship, this three-masted schooner is now a floating maritime museum. It has a length of more than 78 m and a width of 11 m. This beautiful ship is really worth a visit. Great for kids as well.
This tour is available to those who are registered for ICAIS 2022 and their accompanying guest. The cost for the tour is €50. Please contact the Conference Administrator if you are interested in joining the tour. Availability will be on a first come, first served basis.

On this day trip through Belgium and The Netherlands, participants will visit:
- A marina with a large variety of alien marine seaweeds, worms, crabs and sea-squirts. Using pre-deployed settlement plates, scrape nets, hand dredges and gelatinous zooplankton nets, you will encounter a large selection of alien species, like the beautiful purplish feather worm Bispira polyoma, which was introduced to Europe relatively recently.
- The impressive, large Eastern Scheldt storm surge barrier.
- A Pacific oyster reef, as far as the eye can see. If time, wind, and tides allow, we will also make a short stop to check out the basket-ball sized Biflustra grandicella colonies, Pacific bryozoans known to inhabit only this site in Europe.
- A Belgian inland freshwater canal with its alien inhabitants, among which are various Ponto-Caspian fish and crustaceans.
