The Woodland Trust – Nature Detectives website is such a brilliant site. I signed up to their website about a year ago and have been so impressed with the information that they send. There are lots of free downloadable packs which provide lots of free activities and ideas for your children, depending on the time of year. At the moment there is an Easter Pack, a Minibeast pack, a Picnic Kit, Treasure Hunting and an Adventure pack. They also have a free Bluebell Pack that shows you where your nearest bluebell wood is.
If you are looking for free activities that can keep your children entertained for hours, I recommend having a look at the Nature Detectives website and signing up for their emails or “Liking” their Facebook page:
(Many of these activities are also applicable even if it’s raining ;-))
