We plan on leaving our Ortigia B&B to spend the day hiking in the Necropolis of Pantalica. We will then drive down to Pozzallo to take the ferry the next day. Our luggage will consist of two backpacks and we will take valuables (meds, iPad, camera) in our day packs. We will have to leave the backpacks in the rental car trunk as neither of the two lodging would be convenient. Would we be better leaving the car in Sortino or Ferla? Which town would you recommend for buying a little picnic food before or after the hike?
