Get like 70 shines.
It depends on how mane shine sprites you collected maybe over 70 shines you will get there
There is no set amount of Shine Sprites required to get to Corona Mountain. To get to Corona Mountain, you have to defeat Shadow Mario(Bowser Jr.) in each world. This is usually the 6th or 7th Shine Sprite on the list. At minimum, I would say that it takes 55.
You have to finish level 1-7 in each world. The entrance is behind the shine gate... I think.
If you really wanted to know, why would you ask on wikianswers? Just use IGN. http://guides.ign.com/guides/16713/index.html
You can't.
you need to complete level 7 in each area
You need to have unlocked the rocket nozzle firstand you must defeat mecha-bowser in Pina park (shine #1)Then to reach the cave in corona mountain...Just go near the giant tower with the huge shine sprite and use the rocket nozzle to blast yourself up to it.
89
you need to beat every shadow Mario mission in order to reach that level
