In most Spanish speaking nations I would call this a malecón. A stone-built embankment or esplanade along a waterfront.

The Rambla of Montevideo is the avenue that goes all along the coastline of Montevideo, Uruguay … 

… over 13.7 uninterrupted miles (22.2 km) …

Tourists in Montevideo see the sights by walking, running or cycling. Cycling is best. There’s much to see along the Rambla.

I rented a cheap bike from the hostel one day. Two hours out I got a flat. One hour 20 minutes walking back.

Another day I rented a GOOD bike from the leading rental company. $10 / 4 hours. No flat.
