As I understand it, this year's Fragrance Fest will be slightly scaled back, but it's still an integral part of the PROE Mossel Baai Arts, Culture & Food scene. The map below shows the locations for 2016 but is a bit hard to read. Just click on it and you'll get the 2015 map in PDF format for download (note there are a few minor differences!).
I'll post more info as it becomes available - or keep an eye the PROE MB website.
The scenic route takes you through the rural backroads of Great Brak and Friemersheim where you can visit (by appointment prior to the Fest) the Hakuna Matata Game Farm, Kattekwaad (homegrown olives & olive-oil and olive-oil based products), Die Kraal (a multi-purpose complex whose grand opening coincides with the Feb 26th start of the Fest, where you can expect to find various locally-produced refreshments & handicrafts) and the Friemersheim Nursery.
Of course, you can drive the route, but it's even better on the bike (it's included in the various cycling routes on this website)!
