The best way to access Forio from Naples is hydrofoil Alilauro. The journey takes about 40 minutes. Unfortunately the tickets for tourist are relatively expensive (18 euro + baggage 2 euro pp) - price for tourists is three times higher than for residents. In Forio, there is also a problem with tickets: the Alilauro office during summer is very crowded. It can take about 20 minutes (in a horrific queue) to buy the tickets for 9 AM hydrofoil.
