...in the spring, there's a forest of bluebells at the Hallerbos. There's also a museum: Bosmuseum Hallerbos, Vlasmarktdreef, 1500 Halle, Belgium.
" 'The Blue Forest' is the most important and most extensive forest area between Zenne and Zoniƫn, Beligium. The forest is a crowd favourite thanks to the beautiful purple carpet of bluebells, which bloom around mid-April. The giant Sequoia trees also make a visit to this forest more than worth it." Unfortunately, traffic from countless tourists are threatening this very delicate forest area and the very existence of the bluebell bulbs.
