Porto Rafti is not far from Athens, Athens having three major mountain ranges to the North, North East and East.
To the North is Parnitha which is great for a “Proper” mountain ride, road or off road. Good singletrack there, though, is hard to come by – it’s very steep, so a lot of the trails that start off well soon become a bit of a hike. However, at the foot there is the old royal palace at Varibopi, This is a lovely, wooded area with loads of great singletrack, pick a trail ride it, come back for more!
Pendelli to the NE has a lot of great trails, few singletrack, but the rocky nature of the trail makes even the widest track “interesting”.
For tight, steep, technical trails Ymittos takes some beating, there are some awesome trails there.
I can also put you in touch with some of the locals (all who speak excellent English) if you want to try and hook up with a guide for some of the better trails. Let me know if you want me to give a few of them your email address.
It’s also well worth taking a bike and just going out exploring. The Greeks don’t really worry about rights of way in the way we do. If you’re not wanted somewhere it will be obvious – so feel free to check out any interesting looking trails off-road, just don’t climb gates and fences!
Anavasi[/url] will get you the Greek equivalent of OS maps, and they’re pretty good.
Hopefully that’s given you a few pointers, let me know if you need to know any more…
