A must-see when visiting Brighton is the Royal Pavilion, which reflects John Nash's idea of an Indian palace. The palace is open to the public, and the rooms shown reflect eastern designs. My particular favorite was the Music Room.
In warm weather, join the locals and other tourists for a walk along the boardwalk. I don't advise swimming at Brighton, as the beach is rocky and the water is freezing, even in summer. On a warm sunny day, though, it's a pleasant place to sunbathe. Visit the Palace Pier, and sample some Brighton Rock candy.
For shopping, peruse The Lanes, where you will find many antique dealers, bookstores and various boutiques.
Quick Tips:
On one trip to Brighton, I took a bus from Brighton about 10 minutes east to the village of Rottingdean, where I visited an old Norman church and Kipling Gardens. I was told that at one time Kipling lived in the village.
Best Way To Get Around:
There is frequent service from London's Victoria Station to Brighton; the journey takes about an hour. Once you reach Brighton, you can easily see the sights on foot.
