In reply to springfall2008:
Cragwise:
Shorn Cliff: Lots of lovely single pitch climbing on pockets and conglomerations. Especially good in the VS - E2 band. 100% Trad.
Wintour's Leap: The biggest Wye Crag, some good multipitch routes, wide range of grades, some polish (especially on popular Fly Wall routes). Mix of Trad and Sport, Woodcroft Quarry has the highest concentration of Sport Climbs, but there are other bolted lines dotted around. Generally the Trad is better quality than the Sport. Best lower Wye crag for sub VS routes.
Ban-Y-Gor: Underrated Crag, paths at base can be tricky to navigate, and doesn't get so much sun, but there is lots of good steep Sport climbing available, the Main Crag is the best area, top routes in the F7s, but plenty of worthwhile easier stuff too. Accessible from the same Lancaut lane parking area as Wintour's Leap, so easy to do a split day. Some remaining Trad lines, but predominately a Sport crag.
Wyndcliff: 100% Trad. Long single pitch Trad routes, some great lines in the VS - E2 band. Often strenuous and steep, but typically reasonably well protected. Left Hand crag has a sunny aspect, but is a little neglected, expect some veg. and potentially loose rock in the upper sections of routes. Right Hand crag a little more popular.
Wynd Cliff Quarry: Convenience roadside Sport crag that has seen lots of recent development (a few Trad lines remain). Nothing exceptional, but great for mileage, best stuff largely on the Upper Tier. Easily combined with Trad at Wyndcliff.
Tintern Quarry: Sports venue with lots of loose rock and dubious access situation. Loads of routes, but there are better options in the Wye.
Symonds Yat: 100% Trad. A bit further North than the other crags and as comments above indicate a bit of a Marmite crag. There is good steep climbing across the grades available, in a decent dry spell it can be a really rewarding day out, definitely a crag where it is worth seeking the starred lines, a lot of the more obscure stuff is pretty esoteric. Some good (if polished) sub VS routes available.
Here's a ticklist that highlights some of the best Trad and Sport offerings on the Lower Wye crags in the Rockfax Orange Spot zone (F5a - F6a+ & HS - HVS):
