If it feels right, go for it. Pay in mind though, she may be uncomfortable to be alone in a very secluded place with you on the first date, especially if you didn't know each other well before this point.

Yeah dude, if she is into you, just go for it. Look deep into her eyes for a minute, say nothing and let her wonder what it is... and then just go for a quick but a passionate kiss... make sure it lasts for 3 seconds which surprises her and then if she responds to your kiss, then you're smart enough :) Good luck !!
