I am going to visit frankfurt ( Germany) will you tell me which place are best nearby frankfurt to visit?

We took a rhine river cruise and it was fabulous. If you like wine, consider taking the train to one of the wine towns and sampling the drink. We also took the train to Koblenz and went to the Fort & Museum and just wandered around this gorgeous town.

Try the Rhein valley. drive towards Koblenz, with a stop to the villages of Oberwesel, SanktGoran, etc... Can also do this by river boat starting from the center of Frankfurt. I did it this summer, and loved the scenery and villages. Special event: "Rhein on fire" if you catch it.

Wiesbaden, Hanau, Buedingen. Like the other answer already said, you have to take a train to go there if you don't have a car. Trainconnections in Germany are superb. If you go now, don't miss the x-mas markets. Maybe you take a day trip to Nuernberg and visit the famous Christkindl Market. I forgot: Heidelberg

There are so many places to go... I was there just 3 months ago and went to Karlstein, Aschaffenburg, Benshiem etc. But you need to take the train though. Take a day trip to perhaps Koln or Dusseldorf.
