There are few activities that better complement romantic London getaways than visits to the capital's resplendent royal residences. And if you're staying in the city centre, you'll have Buckingham Palace itself on your doorstep – a must-visit for anyone fascinated by the past, present and future of the British royal family.
That's not to say a trip further afield won't yield equally substantial rewards, though. Windsor Castle is a short journey by rail from London's Waterloo and Paddington stations, and it's an exceptionally sumptuous venue to visit. What's more, for the duration of August and September, you'll be able to climb the world-famous Round Tower.
Rising to nearly 70 metres in height, the tower is one of Britain's iconic landmarks – and from the top, visitors will enjoy an unparalleled panorama of the London skyline and the Berkshire countryside.
Climbing up 200 steps, they'll have a bird's eye view of Windsor Castle into the bargain. The royal residence's 5.3-hectare site comprises the Lower Ward, which includes the medieval St George's Chapel, the Middle Ward – where the Round Tower itself is located – and the Upper Ward, crowned by the luxurious State and Royal Apartments.
Gazing further south, they'll see the five-kilometre Long Walk – a spectacular feat of landscaping overseen by Charles II in the 17th century. Further still, the spires and skyscrapers of London emerge – the Shard, Canary Wharf, St Paul's Cathedral, and so on.
The climb takes approximately 45 minutes and Windsor Castle suggests visitors come in sensible shoes so that they're suitably equipped to accomplish the ascent.
Tickets cost £25.25 for adults and £15.15 for under-17s. Students and over-60s also enjoy a discounted rate of £22.90.
Admission includes entry to Windsor Castle itself as well as a tour of the Round Tower, so visitors will be able to take in the building's magnificent interiors in addition to the views from above.
