In reply to mrsmesh:
Joe's original on the slab at Froggatt is probably more classic than the arete. But Froggatt is a bit thin on classic boulder problems compared to the density at places like Stanage, Burbage.
For a long day, how about doing the Burbage Valley - all 6a or below:
Burbage Bridge for a quick warm-up, then...
Burbage North (Banana Finger, Sphyinx Arete)
Burbage South (Pockman, Tiger)
Secret Garden (The traverse probably doesn't have any single move harder than 6a)
Mother Cap (have a go at Conan - probably 6b but you'll be well warmed up)
Owler Tor (I think there's some good stuff, can't remember anything really classic tho)
Higgar Tor (The big triangular slab)
Burbage West (that groove thing on the buttress left of West Side Story)
Then ice-cream.
If it rains then bouldering fun can still be had on the limestone - Rubicon, Raven Tor, maybe Stoney.
