A few friends and I are in the process of setting up something fairly similar in local woods here, although we are approaching it from a home-ed pov (although parts of what we’re setting up will be open to schooling families as well). We are currently going through the process of applying for funding to develop this and two possible funders have been identified. We’re currently firming up our ‘shopping list’ which pretty much consists of things like beanbags, string, crayons, etc. Also looking at prices for all-weather clothing (you can get fab all-in-ones that might be handy for the younger ones to enable them to get nice and muddy without parents needing to worried about their clothes :D )
At present we run a small home-ed group from the woods and are now expanding to offer a ‘Woodland Parent & Child Group’ (so something a little different from the usual p&c groups in church halls, etc.) We have access to the Visitors Centre so if it does happen to hail (and it has in the past) we do have somewhere to retreat to if necessary. We have also organised Ranger-led activities for an older age group (7-12) and are now in the process of organising a ‘co-op class’ (Steiner/Waldorf-inspired) for 6-8 year olds. We also have access to a portacabin if we wanted a further room which means that there is the possibility, in the future, of offering a further age-related activity (either for kindergarten 3-6 year olds or for 9+, depending on the interest).
I am currently doing the planning for the Parent & Child class (nature-themed circle times, etc.) and should be having a meeting tomorrow to discuss the set up for the 6-8 year olds (before having a further one with some more of the involved people on Tuesday) so we can all make sure we’re moving in pretty much the same direction re. what we will be doing and how we will organise it.
I may be able to dig out further links on Forest Schools (I have some in my 1000s of favourites somewhere) and no, at the present time I am not lending out Hermione’s watch
