Jenin is a 4000-year-old city now populated by Palestinians. Jenin in the north West Bank.
The most logical way to enter would be to fly into Ben Gurion International Airport in Israel, take a taxi or mini-bus to Damascus Gate in Jerusalem, from the Arab bus station take bus 18 to Ramallah (6.50 NIS, less than an hour), cross into Ramallah and take a shared taxi from the central bus station to Jenin (35 NIS, 1.5 to 2 hours).
Walking is a practical mode of getting around, taxis can be hired as needed.
BEWARE - the town is closed on Fridays!!! (although we did see a man on a camel who was selling camel-milk!)
The church in Berkin, a small town just 10 km outside Jenin. It's considered the 4th oldest church in the world.
Be sure to take advantage of the great bargains that can be found in the many shops. This is a great place to find souvenirs!
There is plenty of Middle Eastern cuisine available; falafel, shawarma, hummus, the works. There are a couple of excellent places near the bus station where the food is instantly made.
There are many coffee vendors.
From the central taxi station, it is easy to travel to many locations within the West Bank.
In 2011feb I passed on foot through the checkpoint at Jalameh, north of Jenin. It was not pleasant (aggressive Israeli guards), but we got through just before the place closed down for a Sabbath-closure of some 30 hours. The taxi to Nazareth then cost us 150 NIS - pricey, but worth it. (The much longer journey from Ramallah to Jenin had cost just 35 NIS per person.)
To Nablus, one can take a service (shared) taxi for 15 NIS or a bus for 10 NIS.
To Ramallah, there is a service taxi for 35 NIS.
