How far is TV tower from bund? are there tickets to go up? Any timings?

The bund is a long sightseeing road, so it is hard to tell the exact distance from TV Tower. But generally you may arrive in around 15min by ferry and 5-10min by sightseeing tunnel.

Going up the tower requires ticket and it costs CNY160 per adult. It is really worth for a try. It is open during 8:00-21:30 and there is no time limit of visit. You will have a great view on the tower. The combo ticket for the tower visiting and round trip cruise/ferry fares costs CNY200. If interested, you can also have a dinner in the revolving resto on the tower.

After visiting, you can walk to the nearby Ocean Aquarium for fun. If time permits, take ferry back to the oppiste bank and walk to Madame Tussaud for a visit.
