It's in sunyshore city. There's binoculars and you can see the Pokemon league through it.
You should be able to enter Mt Vulcan in Pok_mon Light Platinum after you have beaten Professor Ellie. If someone is still blocking the way, it is possible that your game has glitched.
You can just enter at the start

Dodge the searchlights, and when you get to the river, just jump out and hide behind the fence. When the light moves, jump up and hide behind the chimney. Go right, and get the mask from the scarecrow. Wear it to enter the house (which is actually the party at Violet's house).
You go to cianwood city(south and east of Olivine.) Then go near the Pokemon centre. when your there go east and there will be a building with a sign. enter it and talk to the guy there. he gives u a potion sort of thing. now go to the light house and talk to the person near a Pokemon. later on she goes to the gym. go to the gym and challenge her.
