TET Montenegro is a very scenic route and the best months are from June-October to ride it. This is mainly because route goes over the mountains at an altirude of 1000-2000m. Even in May you may come across snow. People in Montenegro are friendly, especially in the mountains, and they will call you in for a drink or a meal. The main alcoholic drink is rakija - a very strong spirit and usually you can't stop at just one so bear that in mind! Camping is free but be well prepared ast even in the summer it can snow!
