Paseo del Morro takes you from the San Juan Gate, towards the entrance to San Juan Bay following the contours of the city walls and directly beneath the imposing El Morro Fort. It is basically a continuation of Paseo de la Princesa. It was originally used as a service road for the western section of the San Juan Wall and in 1998 it was opened to the general public to enjoy unique views of the city walls and El Morro Fort.
One thing to note; Paseo del Morro currently leads to a dead end directly beneath El Morro Fort, so you will need to retrace your steps back to the San Juan Gate, in order to enter into Old San Juan. Having said that, the views across the bay to Isle de Cabras and the views of El Morro make this dead end walk; well worth the detour. There are plans to potentially extend the walk along the north side of Old San Juan with the addition of a new entrance into El Morro Fort, but there appears to be no time frame for this work to be completed.
Just like Paseo de la Princesa, the walk follows the contours of the city walls allowing you to see just how well Old San Juan was fortified. As you walk towards the mouth of San Juan Bay you will pass several Garitas (sentry boxes), strategically placed along the fortified city walls and you can imagine just how imposing El Morro Fort must have looked from ships whose intent was to attack San Juan.
From the San Juan Gate the walk to the end of Paseo del Morro and back is approximately 1.5 miles. There is very little shade along this walk (so make sure you take along something to drink), though there are several places where you can stop and take a break to enjoy the views. Along the walk you will have great views of Isle de Cabras, El Morro Fort, San Juan Bay and at dusk (weather permitting), it makes for a great spot to watch the sun set.
