Hi Ramzy nice report and eye catching photos.
From where do you need to get permission and how? Is it enter the the Wewelthalawa in general or specific areas in Wewelthalawa ?
I got permission from internal communication (Call/Mail).
For non-employees you can visit Kelani Valley Plantations HO and tell your requirement and request permission.
On my previous visit to Wawlagala - we were returned by Gate Keeper and he said to get permission we should visit the Halgolla Factory on a Thursday and get permission from there.
Thanks for the comments.
