The weather hasn't been particularly sunny and warm this summer. Last tuesday I took advantage of a short dryspell and took my boys out for a day of altitude.
Near Apeldoorn, The Netherlands, on The Veluwe is 'Het Klimbos'. It's an outdoor activity centre offering you the opportunity to climb through the pinetrees upto a height of 15 meters. They have 2 junior routes for children who can reach to 1.4m and 4 routes for kids and adults who can reach to 1.8m and one tokkelroute.
Sit back on your couch, fasten your seatbelt and watch the walk through the trees for 15 minutes (it took us more than 3 hrs).
