Cetinje  is historic capital of Montenegro. The city is of enormous historical and spiritual value to Montenegro. During the siege of Ottoman empire, the Montenegro itself had noumerous times been reduced to Cetinje and surroundings.
Cetinje is located in the small valley under the Lovćen mountain. It is founded 15th century by Ivan Crnojevic. His son has there founded the first printing house in the South Slavs - about the time the Columbus discovered America! Due to the strategic nature of Montenegro, it being an independent state on the border of the Ottoman Empire, all of the major European powers had an embassy in Cetinje. For this reason the town has a continental style old town located a thousand miles away from any of the continental cities that the architecture is representative of. It is very much spiritual heart of Montenegro.
Maybe the best way to get to Cetinje. It is less than hour drive from both Podgorica and Budva. Busses to domestic destinations are very frequent.
All roads in Montenegro are two-laned only, and mostly are curvy mountainous roads, so speeds over 70 km/h (43 mph) are rarely legal, and rarely safe.
Road from the coast to Cetinje is curvy, mountanious road, and mist or ice are not uncommon. Road from Podgorica to Cetinje is in fairly good condition.
Cetinje, especially the historical center of the city, is small enough, and everything is within walking distance.
Cetinje isn't a tourist atracttion in a common meaning of the word. Montenegro's coastal resorts are definitely more amusing. Visiting Cetinje is really about understanding Montenegro and it's history.
If you are looking for a genuine Montenegrin souvenir - Cetinje is the town! Other than that, Cetinje is not really a shopping resort, leave that for coastal towns or Podgorica.
Cetinje is the right town to try out traditional Montenegrin cuisine. The praised restaurant "Konak", just a few minutes drive down the road towards Budva is good choice. There are few excellent traditional Montenegrin restaurants in the village of Njeguši. Going down to Rijeka Crnojevića village is also good choice, as you can enjoy great meals in its beautiful natural setting.
Be sure to try njeguški pršut (smoked ham) and njeguški cheese. The main courses are boiled lamb, lamb cooked in milk, cicvara in fresh milk cream (buttered corn porridge), boiled potatoe with cheese and fresh cream (kajmak).
Montenegrin quality wine is a must-try. The best known Montenegrin wines are the premium "Vranac", "Pro Corde", "Krstač", "Cabernet", "Chardonnay" and the famous home made Crmničko red wine.
Grape brandy (rakija) "Montenegrin loza", "Prvijenac", "Kruna" or home made grape brandy (lozova rakija, lozovaca) is also great.
Apart from renting rooms from the locals, the only choice is to reside at the Grand hotel (***) at the city center. There is also nice hotel in the peaceful environment of Rijeka Crnojevića.
