The Paseo de la Princesa stretches for about 980 feet (300 meters), ending at the magnificent Raíces Fountain. Along the way, local vendors and stalls offer refreshments and souvenirs. The Paseo de la Princesa is also a great starting point for tours of Old San Juan. Walking and Segway tours typically take in the highlights, such as El Morro, La Fortaleza, Plaza de Armas, or Castillo San Cristóbal. Popular add-ons to an Old San Juan tour include a boat ride, snorkel trip, salsa lesson, or a visit to the Bacardi Factory.
