Windsor is one of the closest destinations to Heathrow — around 11 miles via the M4 to junction 6, then the A308 into the town centre, typically 20 to 30 minutes depending on traffic. It's a route we run constantly, largely because Windsor Castle draws huge numbers of visitors flying directly into Heathrow specifically to see it, often as their first stop in the UK.
Beyond the castle, we cover Eton, Legoland Windsor, and the wider area used for Royal Ascot race days — a route that gets notably busier during race week, where booking ahead matters more than usual. Because it's such a short run, it's also a popular choice for same-day return trips: dropped off in the morning, collected again in the afternoon.
