I've always celebrated the Pagan Festival of Samhain in some way, largely becuse there's nothing much between now and mid winter. Since my son arrived it has evolved slightly to include 'Halloween' (which I don't really approve of).
Myself, my son and nephews (8,7 amd 10 respectively)meet at my sister in laws house we then walk 2 miles to my house , stopping on the way at both Grandparents and 2 friends where the kids are given some sweets. At my house I cook a seasonal feast which includes pumpkin and chicken curry, and what the kids gleefully call 'Bleeding Eyeballs' but is actually lychees and Raspberry Coulis. I set lighted candles in the garden to remember all my friends and family who have died and then we eat honey cakes and drink mulled cider/apple juice.
Then we all go inside and watch a good movie.
The kids love it because they love doing the long walk in the dark, there are lots of trees where we live so the wind blows them around and the kids think it's 'creepy' and I realised that most of the time they never go out when it's dark they always go by car.
