The sea crashes into the sea wall along Havana harbour
We were at Parque Historico Miltar Morro-Cabana as part of our tour. The only non-water way to get to the park is through the harbour tunnel. It was interesting to wander along the area, but I found the view far more interesting. I could watch the sea all day.
Here's the sea wall again, but from the city. The military park is in the background.
This is a pedestrian way in Old Havana from near the Havana Plaza down to the sea wall. It made a lovely walk.
