If you visit Lisbon, set aside time for a day at the beach. Cascais is just a 40-minute train ride from the city. In the late 1800s and early 1900s Portugal's royal family made this once sleepy fishing village their summer home. Spend the morning under the shade of a beach umbrella and then explore the small city by foot. You'll be able to smell the fresh catch being hauled up at known as the Praia dos Pescadores or Fishermen's Beach. Above the harbor you'll see a statue of a mermaid that is supposed to keep watch over Cascais' fishermen until they return safely back to port. Make a stop in, Palacio de Conde de Castro Guimaraes, which has thousands of rare antiques on display. If you like boats, arrange a sailing with one of the yachts in the harbor.
