Swingers West End
Though you may know it as a cocktail bar, quirky crazy golf venue Swingers opens its doors to under 18s every single Sunday before 6pm. You and your kids can work your way around their wacky nine-hole course, with a fairground theme that includes ferris wheels and lighthouses. And if you're looking to plan a birthday? They're also offering a round of golf, party food, ice cream and a reserved area for 90 minutes, all for just £35 per person.
