The municipality is mountainous in the north, at Alejandro de Humboldt National Park, where it overlays the Sierra Maestra (mountains), and borders the Windward Passage of the Caribbean Sea in the south. It is crossed by the Bano, Guantánamo, Yateras, Guaso, San Andrés, and Sabanalamar rivers. The city is spread with a square plan and is crossed in the middle by the Carretera Central highway. Guantánamo Bay is a natural harbour south of it.

About 15 km away from the city lies the Guantánamo Bay, a superior natural harbor which has been utilized by the United States since 1898, when it was captured from Spain in the Battle of Guantánamo Bay. Cuba leased it to the U.S. in 1903 in fulfillment of a commitment made in the 1903 Cuban–American Treaty of Relations, and remains the site of a US Navy base, as well as the Guantanamo Bay detention camp.
Notable natives of Guantánamo include athletes Joel Casamayor, Erislandy Lara, Yuriorkis Gamboa, Yumileidi Cumbá, Jaime Jefferson, Yargelis Savigne, Dayron Robles, Luis Delís, gymnast Annia Hatch, Broadway and movie actress Olga Merediz, musician Diamela del Pozo, cosmonaut Arnaldo Tamayo Méndez, journalist Iliana Hernández and Major League Baseball player Luis Robert Jr. of the Chicago White Sox.
In July 2019, Cuba received its first new train cars in over four decades from China for the route between Havana and Guantanamo. The journey takes 15 hours. A round trip ticket from Havana to Guantanamo trip starts at 200 Cuban pesos ($8, €7). 
" Guantanamera" ( Spanish: "from Guantánamo [feminine]", thus "woman from Guantánamo") is perhaps the best known Cuban song and that country's most noted patriotic song. In 1966, a version by American vocal group The Sandpipers, based on an arrangement by Pete Seeger, became an international hit. The song was later also one of Cuban superstar singer Celia Cruz's biggest hits.
