The poet is perhaps travelling and has to pass the woods. The poet is enchanted by the beauty and enigma of the woods that is filled up with snow. It cannot be confidently said if the poet is happy or not but he certainly is filled with a sense of calmness and satisfaction as he is able to enjoy the beauty of the woods on the darkest evening of the year. The way the woods and the frozen lake is described tells us that the poet is a lover of nature and his lonely state does not bother him.
