Cities, towns and villages
The county is situated just north of London. The area is quite suburban in character and has the third highest population density for a non-metropolitan county after Surrey and Berkshire which are similiarly suburban in nature. The Hertfordshire district of Hertsmere has the highest percentage of Jewish residents (11% but much larger in certain towns such as Radlett) of any english district outside London.
Hertfordshire is to the north of London and is easily accessible by train. Trains from London Kings Cross will take you to St Albans and trains from London Euston will stop in Watford and Hemel Hempstead. Any of the major roads heading north out of London will pass through Hertfordshire. London 3rd airport, Standstead, connects to many international destinations and to the train services offering connections to London or Cambridge.
Rail links, as mentioned, run north-south but there are no services running east-west across the county so the alternative is bus/coach travel or car
The  riverside garden centre in hertford has a fantastic restaurant by the river side which serves a superb selection of meals to set the tastebuds racing. From a magnificent traditional English breakfast to light lunches, hot and cold snacks, excellent main meals to fresh cream teas.
Hertfordshire is the second safest county in the U.K. The chances of you being attacked/robbed at night are slim, and in the daytime basically none. The only crime you may encounter is at closing time in the larger areas (Watford, St. Albans, Hatfield and Stevenage) around clubs/pubs. Theft or interference with cars may occur, but only if left in the more unpleasant areas overnight.
Usual instructions apply, if a crime/emergency is in progress call 999 or 112 and ask for Police/Fire/Ambulance as needed. There are main police stations (generally open 9-5) in Watford, St.Albans, Hatfield and Stevenage and smaller ones in all the other towns.
Hospitals (with A+E) in Welwyn Garden City (QEII), Stevenage (Lister), St. Albans (St. Albans City) and Watford (Watford General).
