This is an instance of too many words spoiling a sentence. I wish we had context, but the best way to convey the important message in your sentence is this:
"It is dangerous to swim here"
The reason I wished for context is that if someone else said, "I am a very strong swimmer, so it is not dangerous for me"
So then you would say, "Even though you are a strong swimmer, it is dangerous to swim here". Both of your sentences are technically correct (I agree with the other comment, I am not sure if that "you r" is a typo), but worded that way, are a bit awkward.
