Hi, Roma

In a nutshell, #2 is awkward, it should read Swimming in the lake was dangerous for him
That said, there's no difference between them.

Hi Lost_Soul,

How is difference between : #3 "To swim in the lake was dangerous for him" and #2 " Swimming in the lake was dangerous for him"? My teacher said that there was a little different meaning for using a gerund and an infinitive when they are subjects of the sentence.

Thanks,

Minh
