COASTAL WALKS
Pendeen Watch to Ives, Cornwall, 14 miles
This rugged section of the South West Coast Path, just north of Land's End, is one of the toughest, with plenty of clifftop dips and climbs, but also one of the most rewarding. The landscape is wild and windswept, and along the way you'll find an old tin mine, an iron age fort, a lighthouse and the site of a shipwreck. You might spot seals, basking sharks and even whales.
Ravenscar to Scarborough, Yorkshire, 10.5 miles
Breathtaking views over Robin Hood's Bay make this section of the Cleveland Way national trail worth doing. The area was to be the site of a Victorian resort that was never finished – you'll find its spooky remains everywhere. Further on is Hayburn Wyke, a beautiful cove backed by steep, wooded cliffs and a waterfall. Take refreshments at Ravenscar Tearooms at Ravenscar, the Raven Hall Hotel (ravenhall.co.uk) and the Hayburn Wyke Inn (hayburnwykeinn.co.uk).

Lower Largo to Crail, Fife, Scotland, 18 miles
King James VI described this part of Fife as a "beggar's mantle fringed with gold". The walk leads you along the coast from Lower Largo along the Fife Coastal Path, through the lovely fishing villages of Elie and Cellardyke, the larger fishing and yachting ports of Piteenweem and Anstruther, before finally reaching the little harbour of Crail.
Stop off at the fish bar at Anstruther – it's one of the best chippies in Scotland (01333 310518).

Prestatyn to Llandudno, north Wales, 27 miles
By 2012, it should be possible to walk around the entire Welsh coastline. For now, though, try this new path, which was opened on 1 July. It runs along the north coast from Prestatyn to Llandudno's west shore, taking in a colony of little terns at Gronant dunes, and the Little and Great Ormes.

Whitesands to Solva, Pembrokeshire, 13 miles
A moderately strenuous ramble through the Pembrokeshire Coast national park – a landscape of rugged cliffs, sandy beaches and wooded estuaries. This section of the coast path is close to the amenities and beaches of St David's and Solva, and its bus links access make it a good place for short or circular walks. The whole path stretches 186 miles from St Dogmaels to Amroth.
