"If your visit is very short, or you prefer good food to good hikes, another of my favorite trails is the family trail on Lamma Island. Just 30 minutes ferry from Central, this tiny island is another stark contrast to the bustle of most of Hong Kong. A popular escape for expatriates as well as locals, Lamma Island is famous for its seafood which attracts locals every weekend.
A great day trip is to start at ‘Yung Shue Wan‘ with a snack at one of the boutique coffee shops, then take the meandering and easy paved path through the middle of the island, being sure to stop for the island’s famous sweet tofu, and for a break at the beach. The trip across only takes 1.5 hrs, and the final reward is the spectacular seafood from one of the many restaurants lining the streets. Last time I did the walk we sat watching the small boats bob up and down whilst feasting on mussels, prawns and calamari for around HK$30 each"
