Scotland is served by an extensive bus network that covers most of the country. In remote rural areas, however, services are geared to the needs of locals (getting to school or the shops in the nearest large town) and may not be conveniently timed for visitors.
First (www.firstgroup.com) Operates local bus routes in several parts of Scotland.
Scottish Citylink (www.citylink.co.uk) National network of comfy, reliable buses serving main towns. Away from main roads, you'll need to switch to local services.
Stagecoach Operates local bus routes in many parts of Scotland.
National Entitlement Card (www.entitlementcard.org.uk) Available to seniors and people with disabilities who are Scottish citizens; allows free bus travel throughout the country. The youth version, for 11- to 26-year-olds, gives discounted travel, and SYHA members receive a 20% discount on Scottish Citylink services. Students do, too, by registering online.
