I visited Faroe Islands few years ago in autumn, this was primarily a birding trip and actually was combination trip of Faroes and Iceland with the connection between two on a ferry (yes, the ride across North Atlantic was somewhat bumpy). So, we arrived to Vágar Airport in the Friday afternoon, spent few hours touring the neighbouring villages and then headed to Tórshavn, where we took the ferry to the southern-most of Faroe Islands, Suðuroy. There we spent the weekend touring that island quite thoroughly and early in the Monday took the ferry back and spent some time in Tórshavn surroundings and in the afternoon boarded the bigger ferry heading to Seyðisfjörður in southeastern Iceland, from where we continued next day to the west and couple days later took airplane from Keflavik to back home.
The scenery is fantastic, plenty of sheep all around and there even was some birds to observe, although for seeing puffins on their nesting sites the time of the year (late September, early October) was too late since these birds had already headed to the sea for the winter. Also the most hectic tourist season was certainly over, I guess in Tórshavn there was few tourists - at least those who were traveling on MS Norröna all the way from Denmark to Iceland, but I would guess we were about only foreigners on Suðuroy that weekend. I would assume that Faroes might be still clearly less crowded than Iceland even in the height of the summer when there is more visitors. I think probably most people would have been able to communicate in English, although we were joined by a local birder (if I understood correctly there is about six serious birders in Faroe Islands), who helped us with the communication. Also knowing the second official language of Finland, Swedish helped to decipher some of the texts in Faroese since these two languages are related (but not really mutually understandable). The signage and such seemed to be primarily in the local language.
