We stopped in Santa Clara and walked around.
We then visited the Che Guevera National Monument which was impressive. His remains were brought back from Bolivia and he is interred with his comrades. There is an exhibition with his personal items, you cannot take your bag or camera with you .
Here was a letter Che had written to Fidel.
You must visit this monument on your way back to Havana.
I thoroughly enjoyed Cuba, learnt so much and urge you to visit before it changes!
