you need to practice a lot to take sunrise, especially you want a perfect sunrise.
I suggest you just go a place which is most convenient for a start.
as sunrise is different thru out the whole year, some places only good for taking sunrise in particularly time of a year.
and also not everyday will have nice sunrise.
you will be very disappointed wake up very early, travel for an hour, set up every ready to shoot, but found out the sun don't show face at all.
after you have the experience and knowledge, you can start to try other venues, some venues you may have to come back a few times just to get a decent sunrise shot.
hope this help.
