I've written about the 'elusive' Lake Weyba before, and how it's a bit out of the way, requiring a bit of a hike to see it in all its glory. Well today I stumbled on the easy way!.
There's an area called Weyba Downs, and you can drive right up to the lake, stroll along the shore, picnic in parkland.The lot! Just take Eumarella Rd, westward from one of the Emu Mountain Rd roundabouts, just south of Noosa.
Google Maps marks a 'Weyba Tree', which I think is this one. A lot of spectacular photography has been done of it at sunrise or sunset or both. I'll have to return and see what I can do.
