Solfatara is a short walk uphill and round couple of bends in the road. Inside the crater there are very active steam vents (fumaroles) visible but apparently the crater is almost dormant in comparison to its glorious past. There is however a bubbling mud pool in the centre and signs of sulphur deposits from deep within.
The stench is quite strong near the most active areas, enough to delight the kids after they are tired of culture!
We ate a picnic in a pleasant dedicated area suitably far from the fumes and then continued back to Naples by Metro.
