The full Lakes 508 bus service, including the scenic journey over Kirkstone Pass between Penrith and Windermere, runs seasonally from Easter until November. For 2025, the summer timetable is scheduled to operate from March 31st to November 2nd.
During the winter months (November to Easter), a reduced service operates only between Penrith and Patterdale, avoiding the high Kirkstone Pass due to wintry weather conditions.
