Walking the coast path in four days
We planned the route around the tides, which in hindsight was the only planning that mattered. Two of the beaches are only passable for a few hours either side of low water.
Pack less than you think. By the second day everything that was not water, food or a rain jacket felt like a mistake.
The best stretch was the one we almost skipped: a detour inland through a valley of old orchards, completely sheltered from the wind.
