Tucked between Middlesbrough and Newcastle upon Tyne, Hawthorn Dene Nature Reserve is the kind of place most people drive past without a second glance. That's precisely its appeal. This 100-plus-acre reserve on the Durham coastline combines two things that rarely share a postcode: dense, shady woodland and a rugged North Sea shore. And because it's overlooked by tourists and locals alike, you'll often have the cliff-top views to yourself.

A dene, from the Old English "denu" meaning valley, is a distinctly northern English feature — a narrow, steep-sided wooded valley running down to the sea. At Hawthorn Dene, trails thread through gnarled trees where deer are regularly spotted and woodpeckers and stonechats flit overhead. From spring into summer the woodland floor lights up with bluebells, snowdrops, primroses and wild garlic, before the trees open out into meadows at the coast.

If you want a proper walk, the Hawthorn Wood and Hive Circular is a 4.1-mile loop down to the shoreline that takes around two hours. Hikers on AllTrails warn there are plenty of steps up and down, but rate it highly. Branching off, Haythorne's Plantation forms leafy tunnels that are popular for photos. The trails eventually reach the cliffs, where a steep stairway drops to Hawthorn Hive Beach — a pebbly stretch backed by green-topped cliffs and crossed by the old Hawthorn Viaduct, which spans a gap between the headlands.

One of the nicest things about the reserve is where it lets you go next. From the beach you can keep walking south to Blast Beach at Seaham, a coastal town worth a stop in its own right, with Sunderland not much further up the road. Prefer to arrive fuelled? The medieval village of Hawthorn sits a short drive from the reserve entrance, and the Stapylton Steakhouse there makes a solid pre-walk lunch stop. For an overnight stay, The Barn at Easington is a cosy campground about ten minutes away.

Getting there is easy: under 30 minutes by car from Middlesbrough and around 45 minutes from Newcastle, traffic permitting. It's a straightforward day trip if you're based in either city and craving sea air without the crowds of better-known coastal spots.

This one's for walkers, wildlife spotters and anyone who likes their beaches quiet and their trails shaded. Come in late spring for the bluebells, wear decent shoes for the steps, and leave time to amble the shoreline afterwards — the reserve rewards those who don't rush it.
