Hallerbos – The Valley of Bluebells

Spring. Just the mere mention of it invokes a riot of colours in blooms and a clean slate of a sky to rejuvenate the year. It’s the season of rainbows and unicorns, daffodils and fresh blooms. What if there is a blue forest somewhere? Imagine walking past a valley in a forest lined with a carpet of blue and not the usual green. Imagine the entire expanse of your sight awash with blue and purple, slightly swaying in the spring breeze, the bells of the flowers making a silent noise. Well, if you are in Western Europe, do not waste time on imagination and head straight to Hallerbos forest in Belgium which turns blue every Spring.

How blue is my valley?

I haven’t been to many forests, but this one tends to welcome you with its open arms of beeches and sequoia, their young tender leaves imparting a serene hue of green all around. The leaves have just sprung up at the advent of spring, their colour and density changing by the day. Their transparent leaves filter the sunlight and spread their warmth upon the bluebells.

The blue in Hallerbos hits you right at the start of the trail. There’s a simple theory – the bluebells start blooming somewhere from April and last till mid-May, depending on the weather. The large beeches also begin their sprouting season almost simultaneously. Their young green leaves filter the sunlight that reaches the bluebells on the ground and determines the growth and shade of the flowers. For instance, we were in Hallerbos in the third week of April and the sunlight was fairly abundant, helping the bluebells bloom and retain their bright blue hue. In the subsequent weeks, the beech leaves have increased in density, filtering very less sunlight, resulting the bluebells to turn into a greyer shade of purple and start wilting.
