An otter pops into the marina for lunch

Plymouth, Devon A busy harbour is not a place you'd expect to find much in the way of wildlife, so that bubble trail in the water is intriguing

This is a place of arrivals and departures, a centuries-old harbour where few stop for long. From hosting the steamships and trans-Atlantic liners of the past to today's colossal cross-channel ferries, Plymouth's historic Millbay dock has served the comings and goings of countless travellers.

On work lunch breaks I regularly walk beside the innermost basin, now transformed into a marina as part of the area's regeneration. Solid harbour walls designed by Isambard Kingdom Brunel provide shelter for luxury yachts neatly berthed along wooden pontoons.
