Finding an otter is never easy, but these reserves offer you a good chance and a fun day out.


The return of the otter to waterways across the country is one of the UK’s top conservation success stories.

The species was driven to near extinction in some areas between the 1950s and 1970s, but thanks to improvements in water quality and greater protection it can once again be found across Northern Ireland, Scotland, Wales and - as of 2011 - every county in England.

As with all mammals – a notoriously skittish bunch – the trick to otter-spotting is patience, with a healthy dose of luck thrown in.

How to find an otter

Increase your chances of seeing one by researching the ideal otter habitat. Clean waterways, abundant prey stocks and vegetated banks are otter musts.

The best time to see otters is at dawn but you will need to be still and patient, walk quietly, and keep upwind.

Look for telltale tracks and signs, such as distinctive webbed toe prints in soft riverbank mud.

And spraints (droppings, often containing fish bones and scales) left at strategic points along an otter’s territory, such as beneath bridges. Their aroma has been likened to that of jasmine tea, but you may want to take our word for it.
