How do you get to valor lake front?

Lake Valor is below Veilstone city. If front of the lake entrance there aare two camera men. You cant go into Lake Valor until you get your canalave gym badge. YOU CANT GO IN UNTIL TEAM GALACTIC BLOWS IT UP AND PROF. ROWAN ASKS YOU TO GO THERE.

p.s. when you go to the little housed place the girl who is missing her key its in front of the check in place.
