"Less than 25 percent of Hong Kong's land is developed, and the total area of its parks and nature reserves account for about 40 percent. Also, it's convenient and cheap to take public transport to picturesque offshore islands, where you can go hiking," he says.

Hong Kong's tourism industry has not done well in recent years but it is recovering. And the island and its tourism partners are working hard to promote its tourism resources.

As a result, Chinese mainland travelers are now paying more attention to other aspects of Hong Kong - its natural beauty, cuisine and unique culture, rather than just shopping.

Kang also says that Chinese mainland tourists are now visiting places that are not regular scenic spots, and he has a few recommendations.

He says tourists can stroll around the Central district without a map, taking the long Central-Mid-Levels escalator and walkway system and immerse themselves in the old streets lined with small shops and restaurants.

The Dragon's Back is the best hiking trail for both green hands and veterans, with magnificent views of Shek O, Tai Long Wan, Stanley, Tai Tam, and the South China Sea, he adds.

Visitors can also take a bus to the hillside for sightseeing, walk to the seaside and then go to Shek O town.

As for Lantau Island, they can take a cable car to the mountain top and take a bus to Tai O village to experience the ancient fishing culture, he says.

"There, you can sample authentic food from all over the world - from street food to Michelin restaurants. But it is better to make a reservation," says Kang.
