In reply to Emilysaladfingers:
Sicily is a big small island, Em, and and a bit tricky to get around. If you are just referring to San Vito lo Capo, yes, conditions will be good in April, but it will be very warm, and much of the climbing is south facing or prone to humidity. All good if you can cope with that.
Ive not climbed harder than 7a+, or been with someone climbing harder than 7b, but every route we did at these grades was 3 stars. The routes tended to be long and sustained rather than bouldery, which suits me.
The campsite is usually open all year round, but failing that there is apartment accommodation in San Vito itself.
Sicily is an extraordinary country, diverse, cheap, historical, and welcoming. I'm tempted myself now...
