Bonnygrove Park

If you’ve got a dog in Middlesbrough, you probably already know about this place. The double gate entry makes it genuinely secure, which takes the stress out of letting your dog off the lead — no bolting for the exit while you’re chatting to someone. What’s impressive is that the locals actually help keep the grass cut themselves, so it stays in decent nick year-round. It’s the kind of spot where you end up knowing the regulars, dogs included.
