I think you can enter Lake Valor once you defeat the 5th gym leader and stop the bomb from happening.
Shoot them.
Pastoria City is below Lake Valor. Go right out of the city and go down the beach, turn right and then when you see the two children, go up into the lakeside hotel reception. Go through and keep going until you pass the lady who has lost her key outside her hotel door. Carry on and turn left into the trees and there is Lake Valor! Team Galactic will have messed it up and you can only go in when the galactic bomb goes off. This happens when you follow the galactic grunt that is outside the Great Marsh entrance. To restore lake Valor, defeat Cyrus at the Spear Pillar and battle/capture Dialga/Palkia/Giratina. Alternatively, go south from Veilstone City. Look at your map. Simples! ;) Hope I helped! :)
First you to go to Mt.Coronet and catch or kill or make Palkia escape and then go to Valor Lakefront to the Lady who lost the Suite key find the Suite key near the Valor Lakefront and the road to Sunnyshore City is open
you need to have helped prof rowan at lake verity. Then you should be able to pass. I got stuck to but I found out by traveling everywhere. Posted by flames fan
