Without a car
Use Foggia as the rail gateway and check SITA’s Convento Cappuccini service for Saint Pio. The Monte Sant’Angelo–Lucera line lists San Giovanni Rotondo and Convento Cappuccini; check the service calendar and both directions. Another line serves Monte Sant’Angelo through Manfredonia from Foggia. These are distinct routes, not an hourly shuttle. If connections leave too little prayer time or no safe return, book the mountain transfer or add a night.
