Depending on where you stay, you should first find out which are the spots ideal for viewing sunrise. Prime viewing spots are normally packed with photographers & tourists, so you must go very early. Be careful when trekking because it'll be very dark, you need to bring torchlight along.
You can find out from local people what time is the sunrise.
Enjoy your trip.
