A couple of friends and I once went for a hike along the South West Coast Path in Dorset. It took…read moreus a couple of hours and was really nice: good weather, beautiful sea views, rolling pastures, and a great pub at the end. That pub turned out to be the Square and Compass.
When we arrived it was warm and sunny, and most people were sitting on the dozens of outside tables, rocks, or just on the grass, enoying the sunshine. Oddly, a large number of chickens were strolling through the assembled patrons, but no one - drinker nor chicken - seemed to mind.
There was a band playing some Beatles covers, too, though they finished shortly after we arrived.
This is a proper country pub, long, low and very old wood and stone. They keep kegs of real ale and cider in a pump room here, so you order at the hatch.
Check the Dinosaur Room while you're there. I won't say any more, since it deserves to be a surprise.
I can't imagine a more relaxed, laid-back, country pub.
The only downside was that although we'd planned to take a local bus back to Swanage, where our car was parked, those services don't run on Sundays. The day was so nice we decided to walk back anyway (along the road, though, a much shorter trip than the coastal path).
EDIT: I was back again today, and despite the weather being crap - or maybe because of it - this pub was even better. We walked down to the ocean, to watch the surf pound the cliffs by the old quarry. We wedged into one of the tiny rooms and ate pasties and drank Ringwood ale. We gazed in wonder at the bizarre little fossil-and-beach-item museum at the back.
