One Traveller is a family-run travel company specialising in escorted holidays for mature solo travellers, particularly people aged over 50. Founded in 2007 by an experienced tour manager, the company aims to make travelling alone welcoming and sociable, bringing guests together with like-minded people while exploring new places. Its tour managers accompany holidays and support guests throughout their journeys.

The holiday collection spans the UK, Europe and destinations worldwide, with options including river and ocean cruises, rail journeys, festive breaks, music trips, walking holidays, and leisurely, moderate or adventure experiences. Trips feature hand-picked hotels or solo cruises, and each guest has their own room without paying a single supplement. Many meals, excursions and additional touches are included in the advertised price.

For those considering their first solo trip, One Traveller provides booking information, testimonials, accessibility advice and brochures to help guests choose a holiday. Guests can also manage bookings and access travel documents through an online portal.
