The Tinos-Bloc guidebook describes the bouldering found on the Greek island of Tinos in the Aegean Sea. On Tinos there is a 20 sqkm granite bouldering field and this guidebook covers over 600 problems across a wide range of grades. In total 16 different sectors are described, however there is potential for developing many more problems and the guidebook indicates where this potential is. At the start of each sector there is a good location map, a general description of the area, and a topo-map of the boulder field. All the problems are then illustrated on full colour photo-topos with Fontainebleau grades. The guidebook also includes numerous colour action photographs showing the excellent bouldering to be found on Tinos Island. Published in 2008 the guidebook is in German, Greek and English text. Number of pages is 96. Format 150mm x 210mm (A5). ISBN is 9783938680070.
