Sciacca is not really on the tourist trail although it is extremely pleasant and some of the upper town is really picturesque. There is no really cheap place to stay, though the Paloma Bianca in Via Figuli was not really dear. The main appeal of Sciacca for me is the fact that it is an ideal place for an excellent bus trip to the hill village of Caltabellotta. Sicily has so much to see [I missed the lovely west coast and most of the interior, including a terrific Roman villa] that I suspect a lot of people never make it to any of the smaller towns. Even though I obviously saw them at the cost of some better known larger places, Erice in particular, I feel that it is a pity not to sample some and this is a beaut. From my knowledge of Sicilian hill villages I would say that somehow they are less picturesque from a distance but quite as good when inside them as those of the mainland. On the ride to Caltabellotta it is going up high, rather than heading for the village, which gives the pleasure and you need to be well up in the village to see it at its best.

Having said that, once you go up from the bus terminus to the very top, you will certainly want to find ways to other parts of the crest. In one place you can go through a tunnel to see the magnificent view from the other side – if you are fully fit you could actually get this from the castle. The wind that hit me from the other side as I came out made it feel about fifteen degrees lower temperature. No doubt this is a considerable exaggeration but it was a great feeling in the reverse direction! Here there are two fine churches just below vast rock outcrops, one Norman and one Gothic. I use ‘Norman’, rather than ‘Romanesque,’ as a descriptor because the Normans did actually get to and settle on Sicily, unlikely as that may sound. I really go for rooftop views as well and the town below looks far more stunning to me from up here than from below.

This was only my fifth night out of eleven but already lack of time was forcing me to adjust my plans. I had meant to go right around the island anti-clockwise and hopefully to do a trip into the Villa Imperiale inland. I now realised this was far too much to take on and I abandoned any notion of reaching the west coast or Segesta, a spectacular site to the west of the island’s capital, Palermo. This meant cutting from the south coast to the north at Palermo itself. I decided on one further southern escapade first – a trip to the ancient Greek settlement of Selinunte It was necessary to change at Castelvetrano from the bus bound for Trápani to the local minibus to Selinunte and the modern village of Marinellla which is little more than the accommodation for those going to see Selinunte. It turned out that the wait in this rather ordinary place [Castelvetrano] was going to be over an hour and a half, and then when the bus was quarter of an hour late.

This afternoon was well up to the standards of the very best parts of my trip. Not only was the sun shining warmly from a blue sky but the spring flowers were blossoming in profusion all over the site and beyond. The site itself is terrific – as good a set of Greek remains as that at Agrigento to my mind and I felt that to have missed it would have been unpardonable. There are three areas of particular importance: the eastern temples, the Acropolis area and, some distance away, the Necropolis. I concentrated on the first two. This in itself covered a considerable area and involved several kilometres of walking but I am sure the number of people I saw was not as many as eighteen.

The eastern temples were mainly erected in the sixth century BC and one of them, Temple E as it rather prosaically named, was reconstructed in the 1950s. Apparently this was and is controversial but I feel no qualms about it as long as some are left as they are found. Whatever, it is a magnificent building and I am sure a full size re-construction must be the best way of illustrating to children what these temples were like. The Acropolis area contains another five temples and most of the ancient living area as well as the remains of the great walls. These walls, however, are older than the rest of the remains, having been built after the city had been destroyed once by Carthage in order to defend the high ground from further destructions.

David was a keen walker, particularly on mountains before he developed serious heart problems in 1995. He has now adapted his holidays to what he is able to do and we are presenting his account of 12 days in Sicily over this and the coming months. Next two episodes: Palermo.

What is it: Rift Valley fever (RVF) is an acute, fever-causing viral disease that affects domestic animals (such as cattle, buffalo, sheep, goats, and camels) and humans.  RVF is most commonly associated with mosquito-borne epidemics during years of heavy rainfall.

Where could I get it: RVF is generally found in regions of eastern and southern Africa where sheep and cattle are raised.  However, RVF virus also exists in most countries of sub-Saharan Africa and Madagascar.

What happens if I get it: people with RVF typically have either no symptoms or a mild illness associated with fever and liver abnormalities.  In some more extreme cases, it can lead to hemorrhagic fever (which can lead to shock or haemorrhage), encephalitis (inflammation of the brain, which can lead to headaches, coma, or seizures), and eye disease.

What do I do if I get it: usually patients recover within two days to one week after onset of illness.  About 1% of humans that become infected with RVF die of the disease.  There is no specific treatment – just rest and taking plenty of fluids.

How can I prevent catching Rift Valley Fever: avoid bites of mosquitoes and other blood-sucking insects, so use of mosquito repellents and bed nets.  Also you should avoid exposure to blood or tissues of animals that may potentially be infected.

I went to St Moritz for a week in February – on a course in a place called Randolins in Survetta, a little way outside the town – not skiing.  Randolins is a not for profit organisation that caters mainly for groups, such as children on ski camps or adult learning.  It's a very nice place, simple, but comfortable – definitely not your 5 star kind of place.  It has shared rooms and you have to take part in the chores, so things like going and getting the food for each meal and wheeling it down to your building on a trolley, washing up, laying tables etc.  If you are looking for a group venue, it's not a bad place.

St Moritz is in the Upper Engadine.  Can't comment on skiing, but can say a few things about the town.  It's quite small, easily walkable, very posh with a very high fur coat count and is pretty expensive!  There are two parts to St Moritz: there's the dorf which means village and this is above the lake.  This is where the posh hotels, restaurants, shops etc are.  St Moritz-Bad is about 2km away southwest down on the lakeshore and is not such a pretty place, lots of concrete flats and other buildings.

The name of St Moritz has an interesting story attached to it: the story told to me was that Maurice (later turned into Moritz) was a Christian and came from Egypt.  He served in the Roman army under Julius Caesar and led a Theban legion for the Roman empire and fought in the Alps.  He refused to obey the order of the Emperor Maximian and sacrifice some Christians to the Roman gods because he was himself a Christian.  On hearing this, Maximian ordered Maurice's regiment to be decimated – i.e. every tenth person killed, and this went on until no-one was left.  And so commanding officer Maurice became a saint.  Legend has it that the rock used by Maurice to lay his head on so that he could be beheaded is at St Moritz.   Like England's St George, St. Maurice is a patron of knights and soldiers.  From the 12th century, due the similarity between his name and Maurus, he was depicted as a Moor, so he became the black saint.  

Even after Roman times, St. Moritz was known during the Middle Ages for its mineral springs and healthy climate and it became the first alpine winter sports and tourism centre in Switzerland.  It also hosted two Olympic Winter Games (1928 and 1948.) It became the famous ski and alpine sports centre that it is mainly due to the British, who went over in the 1860s and liked it so much they went back and stayed an entire season, and the word was spread.

To get to St Moritz is very easy, you can take a train from Zurich.  I flew from London to Zurich on Easyjet (AKA Sleazyjet) and that was a good price at around £75 including taxes.  Swiss Air and BA all fly there too from the UK but are more expensive.  There is a train station underneath the airport at Zurich and you can take a train from here to the main train station in the centre and go to Chor, change there for St Moritz.  The whole train journey from Zurich took about 3 1/2 hours. 

There are plenty of taxis outside St Moritz train station and the drivers seem to speak every language in the world between them.  Swiss Italian and Swiss German seem to be the predominant languages – and be warned, whilst many Swiss people are amazing linguists and speak good English throughout, if you were thinking (like me) to practice your German, think again, Swiss German is quite different.

Swiss trains are a delight – always on time, clean, and I especially like the double decker trains.  Whilst the airport is non smoking throughout – a fairly recent change, I think, the Swiss do allow smoking on trains, so be careful about which compartment you get into, if you are a non smoker.  I got on an intercity from Lucerne to Zurich and inadvertently sat in a smoking section, which by the time I realised, was too late to move as it was packed full.

Buying a Swiss rail pass makes a lot of sense.  I paid £105 for a pass that allowed me free travel on three specified days.  The days do not have to be consecutive.  The pass also allows you to receive substantial discounts on other trips.  You can buy rail passes for different lengths of trip.

I also went to Lucerne or Luzern.  Beautiful!  It's about 4 hours from St Moritz by train – and only an hour or so by the fast intercity train from Zurich, which also goes direct to the airport as well, which is pretty handy.  It is situated on a lake and has lots of history.  The river Reuss separates the old town from the newer, although that seemed pretty old to me too!  Then it flows into the lake.  The town is also very easy to walk around and was my highlight on this trip to Switzerland.  The train station is very close to the edge of the lake and close to the Art Museum and within easy reach of the hotels by foot.

I stayed in the Hotel Krone which is a Best Western and is in the Old Town, it was very nice and has free internet and the people there were very nice.

There are lots of bridges across the River Reuss, it reminded me a little of Ljubljana, especially with some of the dragon symbols, some of my friends said Stockholm.  One of the most famous is the Chapel bridge built in the 14th century as a part of the city's fortifications and named after St. Peter's Chapel, which is located nearby. It has paintings on it including some info on the city's patron saints, St. Leodegar and our friend St. Maurice.  There's also a very splendid 17th century baroque Jesuit church.  I really liked the water spikes that act like a lock  to regulate water levels like in a canal. and you can see the remains of water mills.

There are lots of old squares and beautiful buildings with pictures on the walls, red spires and steeples.  The Weinmarkt is one of these old squares, and is by the Hotel Krone – very pretty. There's also a great restaurant, and not too expensive (for Switzerland!) in the cellar of the town hall, or Rat Haus that has its own micro brewery inside – great beer, and good food, especially the Braui special which has lots of different types of pork and sauerkraut.  It is also a good place to go and talk to local people, as everyone seemed really friendly.

On my final day in Lucerne, I went to the tourist information centre at the train station and asked where I could go in the mountains.  They suggested a trip to Rigi Kulm, so, using my rail pass, instead of paying 79 Swiss Francs, it cost me 29 Swiss Francs.  It was a great adventure!  I took a boat across Lake Lucerne, and then a funicular or cog wheel train up the mountain to the top of Rigi Kulm, about 1,800m, so not too high, and then the cog wheel train to the half way point and a cable car down to Weggis back down by the lake, and the boat again back to Lucerne.  It was a wonderful half day trip, where we could see above the clouds, the mountain tops poking through, then there was the lake and the green of the alpine pastures leading up to the mountains.  There are a couple of other mountain type trips you can do like this whilst based in Lucerne.

Then  I took the train from Lucerne back to Zurich airport, the direct trains run at 10 minutes past the hour and it took about 1 hour.

I’d definitely recommend Lucerne as a base for 2/3 days to explore.
