Instant answer - The Moroccan Anti-Atlas - all the adventure you'll ever need.
Developed almost solely by Brits, beginning with Browns Les and Joe and their mates Trevor Jones, Claude Davies and Pete Turnbull, and later Walker, Bonington, Ross, Wintringhams, Mortimers et al, with the baton taken over in recent years by Alsford, Donnithorne, Broadbent and others it's to all intents and purposes completely free of bolts and there are very few pitons even. British style climbing from single pitch to 500 metre routes of all grades.
And our off season is the time to go, especially early Spring and late Autumn. Plenty of guide books around now too.
But no search and rescue facilities - you're on you're own.
