There's a huge choice of activities during half term, including The Cape - outdoor adventures in Crouch Hill - plus adventure playgrounds in Cornwallis Rd and Grenville Rd. The Community Centre in Whittington Park will be the base for outings and fun activities run by Highbury Roundhouse http://whittingtonpca.org.uk For details of all these and a lot more, see Islington Council's brochure for things to do all over the borough.
