Y’know what Londoners can never get enough of? Big ol’ soggy wetlands. After 150 years of secrecy, Walthamstow Wetlands is opening its big gates to the wider public, inviting everyone down for some wholesome fun. Just a 15min hop, jump and skip from central London, find a wildlife oasis perf for some bird watching, angling or just causal strolling amongst Mother Nature. They've also got a weekly calendar of events that changes on the regs, but you can expect the likes of educational trials, home-building workshops and arts & crafts. Entry to the grounds is free.
