A very popular stop for boats on the Thames is the stretch of river between the neighboring historic towns of Windsor and Eton. There are numerous mooring spots both above and below the 19th Century bridge that links the two communities. Eton College and Windsor Castle are short walks away from the river.
Windsor Castle is amongst the many official royal residences. By tradition, the Royal Standard flies high above the castle when the Queen is present. For tourists, the sight of the Royal Standard is not good news. Access to Windsor Castle can be restricted when Queen is in residence. And, for some reason, the Queen does not routinely invite visitors in for a spot of tea.
