Larvitar Sidequest

[Pam]

I still would like to do the larvitar side quest however I already done the alll the reconstruction side quests including the railroad reconstruction.  I've seen videos on how to enter the area however when I go to the entrance it's blocked.  Did I miss out on an opportunity to get it or is there another entrance I can use to complete the side quests?

 

Thanks

 

Update:  oops forgot there was another entrance...doing this side quest now
