Outside Passchendaele is the preserved trench network, known as sanctary woods. Nowadays, the trenches themselves are covered in sheet-iron and concrete, but are more acessable than the untouched ones that are left. This is the British line, concerning a front-line trench and a reserve trench (Which another school party mistook for the German trenches). They are connected by a tunnel network, which is still acessable (Though we did see a rat down there) but its pitch black, and we were guided by constant camera flashes. The network itself isn't brilliantly taken care of, but for a place that is fully open to the public, its pleasing empty of litter. There is also a small museum, filled with equiptment and photos. What I remember is listed here;
Headgear; Damaged Stahlhelms Brodies Damaged Brodies Adrians British peaked caps French gasmasks Many, many Pikelhaubes; Spiked Ball-topped Feather-topped. German Czapkas German Totemkopf Busbys French Dragoon helmet
Uniforms; British officer British officer, Palestine Various German and Italian body armour
There was lots of equipment, but I'm no personell weapons expert, so sorry. And plenty of medals.
While its an impressive collection, Its rather poorly organized, and the man who runs it, dosn't appear to have any interest in the Great War, but only in making money.
Anyway, to conclude, its worth visting if you're not massively interested, but cuirious about the great war, but there are other places out there which have better to offer.
