hi there,
If you're staying in Havana, one of the top things to see and so it's to see the Malecon.
El Malecon Havana extends a little over 4 miles, from the Bay of Havana at Old Havana, to the northwestern district of Vedado, thus forming the northern edge of Old Havana, Central Havana and
Vedado.
You can get great views of the ocean walking along the Malecon and you can also see locals using the Malecon as a public bath area.
Walking along the
Malecon, starting in Old Havana, the first sights of major interest along El Malecon are the Castillo de San Salvador de la Punta and the Castillo de los Tres Reyes del Morro.
Hope this helps
