Walking and hiking are key focuses for the new additions, said Intrepid, following increased demand for active holidays.
Its eight new trips in England, Scotland and Ireland are designed to support local communities and get travellers off the well-beaten tourist trail.
New experiences include trekking Ireland’s Wicklow Mountains, hiking through forests and paddocks with reindeer in the Cairngorms, and exploring Hadrian’s Wall with a local guide.
There is also a new Scottish Highlands walking holiday designed specifically for families.
