Hi 기린,
First of all, I just translated your full sentence in English so that you can see how I understood your sentence.
Your sentence:
During winter break, my homestay family took me on a 6 hour drive to their log house on the mountains.
It was an interesting and relaxing experience.
In Korean:
겨울방학에 홈스테이 가족분들이 차로 6시간 거리에 있는 어떤 산에 있는 그분들 오두막집으로 데려가 줬어요.
흥미롭고 편안한 경험이었어요.
Hope it helps.
