Arco in Italy. It's on outskirts of Alps and limestone is of exceptional quality. A lot of craging as well as airy multi pitch routes.
1. Fly to Verona
2. Take regional train to Mori, there's 1-2 trains every hour. Ticket is about 5 euros.
3. Catch a local bus 332 or 301to Arco. Ticket is 2 euros.
4. Thousands of sport routes around.
As alternative you can fly to Milan and take intercity bus 40 directly to Arco. But it's expensive and about 4 hours.
Here's info about camping and more beta:

P.S.: for via ferratas you will have to hitch a ride or get around with local buses. Italians rarely pick up passengers, but tourists do often stop for 1 - 2 climbers walking on a road.
