English: View of Cuba taken during ISS Expedition 6. South coast of Cuba, Sancti Spíritus province. Trinidad on the left and, on the right, the Zaza river separating the municipalities of Trinidad and La Sierpe.

• Trinidad

On the left, the first two small nicks in the coast are rio Cabagán (limit between Cumanayagua west and Trinidad east) and rio Guanayara.
Next, the deeper notch in the coast receives both rio Caña and rio Guaurabo.
(satellite view) Then comes the nearly 6km-long peninsula that closes the ensenada Casilda, Trinidad's harbour, and also carries the famous playa Ancon - its sand clearly lining in white the south side of the peninsula.
Ensenada Casilda opens in Casilda bay, which goes east up to the peninsula that carries the Agabama river - still on Trinidad's territory.
East of the Agabama peninsula : bay of San Pedro.
Higuanojo river, marking the limit with Sancti Spíritus municipality.

• Sancti Spíritus

Its coast is not very long. The main characteristic is the Zaza river, marking the limit between Sancti Spíritus and La Sierpe municipalities.
