Erlebnisbad Bahia. We thoroughly enjoyed our stay here. Fun pools with attractions, cave with bubbling water, water slides, lawn (lots of insects there!)
You can reach Bocholt by train. There's just one curve on this 20 km track from Wesel and it takes 23 minutes to travel. Train is called Der Bocholter and it runs usually between 05.02-22.02 from Wesel and between 05.33-22.33 from Bocholt. You can take a bike along, too.
