I believe it is on R.Nossa Sra. da Praia, Praia das Macas. Beach of apples and river of necklaces - Ribeira de Colares. Not that I know any Portuguese, that's what google translate tells me.
And of course, apple strudel...
Hmm, could be Colorado, but I'm a little skeptical. I'm not sure where you have a body of water to get that view, and most of the high rocky areas like that that I'm aware of are not usually conducive to the ATVs (but there's a lot of Colorado I'm not that familiar with so I could certainly be wrong).
In 2006, Quad bike tours were operating out of the recently established Cardrona Adventure Park. Now Cardrona Horse Trekking & Quadbiking and, If that’s the right location, the old Polaris Predators (as in the photo) appear to have been replaced by a fleet of late model Yamaha 350-450cc Quad bikes - “to explore from the valley floor to the top of the Cardrona mountains.” Might be way off there though.
For many years I travelled that Cardrona Valley Road around eight times per year – providing the Crown Range Road was open – my favourite NZ alpine road.
You're in the right area, but the photos are a bit closer to the coast, and a bit further North. Wasn't a guided tour, just a few mates, and we actually got chased out 😁
Very naughty boys ha ha ha
