The valley of the Yumuri, near Matanzas, a small circular basin crossed by a river that issues through a glen to the sea, is perhaps the most beautiful in Cuba.
There are few river valleys that are noteworthy - those of the Yumuri, the Trinidad and the Gaines.
Three rivers emptying into the bay - the San Juan, Canimar and Yumuri - have deposited much silt, necessitating the use of lighters in loading and unloading large ships.
The San Juan and Yumuri rivers divide Matanzas into three districts.
Near Matanzas are two of the most noted natural resorts of Cuba: the valley of the Yumuri, and the caves of Bellamar.
Commanding the Yumuri Valley is the hill called Cumbre, on which is the Hermitage of Monteserrate (1870), with a famous shrine.
