Jeff and Viola are wonderful guests. Their home is perfectly located if you plan to hike in Sai Kung (there is a pedestrial path leading to a ferry which drops you at the beginning of a very nice trail, MacLehose section 2). After a two hours walk you reach wonderful beaches like Ham Tin Wan.
Jeff and Viola came with us, so it was very easy to find and enjoy :)
But if you prefer a more usual stay you would be best located in Sai Kung town, as Jeff and Viola’s home is in a small village, far from the crowd.
