I quite like shopping so I would recommend taking the train to ShenZhen, China for the day. Its a different food and shopping experience than that in Hong Kong. Massage, manicure, pedicure etc is good too!
You could also take a Ferry trip to Macau, its rather pretty and the mix of portuguese and Chinese is interesting.
In Hong Kong I took the escalator upwards but got off to check out the shops, markets and eating places. At the top of the escalator I caught a taxi to the base of the funicular railway. When you get back down you can catch a bus back into town.
A walk down Nathan Road at night is good too. Stop in at the Peninsular Hotel for a "cheap" beer or champagne. The views of the city, at night, from around the star ferry terminal are spectacular. about 10 years ago
There is also the Jade Market which is on the right as you walk down Nathan Road from Monkok. There's lots of Jade and other stones. These are good for presents as the vendors will "string" then up for you into pendants or wrist bands. You select the stones and they make them into something nice. Bargain hard as the cheap pieces really are very cheap! about 10 years ago
Hong Kong is an awesome city - I was really impressed by the skyline, the architecture of the city - modern skyscrapers, lots of glass and you walk around the corner and you are in front of a small temple. I enjoyed walking around the city soaking up the atmosphere and life of the city.
Things to do could be:
Taking the tram on Hong Kong Island - there is one line which does more or less a tour all around there. so you get a sort of sight seeing tour of Hong Kong Island
Taking the cable car up to Victoria Peak - the view over the harbor and the city is amazing!
If you want to spend a quiet day and enjoy some really good sea food take the ferry to Lamma Island (30 minutes). It's a small island, no cars at all, but therefore a beach, banana trees and some really good restaurants! There is even a hostel there!
Nathan Road/Monkok is great at night - typical chinese night market with some interesting culinary experiences and you can buy all kind of souvenirs at reasonable prices.
One of the most spectacular views over the city at night you get probably from the bar "Felix" on top of the Peninsula Hotel in Kowloon. And visit the bathroom there - it's worth it, believe me! almost 10 years ago
If you like to get a view over the city and enjoy a short hike i would definitley recomend the liontrail. It leads to the peaks between new territory and kowloon. You can either walk up from the new territorry side or the kowloonside, however i would walk down on the kowloonsaide anyways as it is shorter and less crumpled... (to hot in the day so you will have to hike in the evening and bring a flashlight). From kowloon it is about 3km to the peak, so just a short 30 min walk! If you get the timing right you might watch the sunset from there... I went there just last week and got some rediculusly nice views over the city :-)
To bad you just missed the beerfest that was going on las weekend. However for drinks, Lan Kwai Fong is always vibrant in the weekends! Also there is many resturants and bars located on Knutsford Terrace in Tsing Sha Tsui in Kowloon as well :-) almost 8 years ago
I'll totally recommend going up the Peak by cable car, enjoy the food (breakfast would be nice) at the Lookout restaurant and do the 1 hour walk around the 'mountain' where you get to see the bird eye's view of HK, 360 degrees.
Shopping is awesome too, so dedicate a day for that. Nathan road at Tsimshatsui, causeway bay... Shopping is all over.
Pubbing at LAN Kwai Fong is nice too. almost 8 years ago
Hong Kong side, peak tram of course, but also a #6 double decker bus from Central over to Stanley market is a great half day excursion. Escalator to SoHo. Foot massage
Kowloon side: Temple Street night market, Mongkok Ladies market, learn how to use subway (very clean and efficient). Avenue of the stars 8 pm harbor side laser light show each night is a must. Try Knutsford Steps off Kimberly Road for enchanting collection of ethnic restaurants and bars. almost 8 years ago
