Sea to Sea (Hebrew ים אל ים) is a hiking trail in Israel, running from the Mediterranean Sea to the Sea of Galilee. It's usually a three- or four-day trip, and a pleasant way to experience the Upper Galilee.
It is essential to have the Israel Hiking Map Number 2. The Israel Hiking Maps are scaled 1:50000 and are very accurate. The trails are marked corresponding to the colors on the map. You can buy one at any camping store for around 100 shekels. For free, about the same information is contained in the "Israel Hiking Map" layer of the OruxMaps smartphone app. But you shouldn't rely just on this, in case your battery runs out.
The trek can be done almost any time of the year except for winter and the peak of summer. The best time is Spring. Be aware of the timing of holidays. During Passover this trek is very popular, especially for Israel's many youth movements.
Watch weather in the area a week prior to starting. Much of the trail passes along river beds that are normally dry or muddy, unless it has rained heavily recently, in which case they are not traversable.
One usually travels from west to east.
Water is not an issue; there is water at the end of every day and sometimes during the day at parks or campsites. Carry enough water for a day. Do not drink out of the rivers or springs because they could be polluted. Bring enough food for the whole trek, although it is possible to purchase some if you choose to hike through any of the towns located along, or not far off, the trail.
You can start on the Mediterranean side by one of two popular options. The first option starts from the shore at Akhziv, six km north of Nahariyya on Route 4. From here you follow Nahal Kaziv. You can reach Akhziv by bus or taxi from Nahariyya. The second option is to start the trek 20 km east and take a taxi or bus from Nahariyya to start somewhere on Nahal Kaziv. A good place is Goren where there is a picnic area. This second option allows for a shorter trip.
It is tradition to take a small bottle of water from one sea and dump it into the other. Another tradition is to dunk your head, or go swimming, in each sea.
From the shore of Akziv follow 3 Nahal Kaziv. The trail will be unmarked but you will know you are hiking on Kaziv because it is the only Nahal (riverbed) starting from the shore of Akziv. When Nahal Kaziv intersects Route 70 there will be a trail marked green. This trail follows Nahal Kaziv. Continue until you reach Ein Zev. From Ein Zev you can hike into Ma’alot and sleep in a hostel or hike northeast of Ein Zev and camp in the national park there. Be aware that there is no water at the national park. There is water available 1 km south in the settlement of Abririm.
From Ma’alot the trail for Nahal Kaziv picks up again on the eastern side of the town at Ein Tabat. If you stayed at the national park you will need to follow the road from Abririm for about 5 km through the town of Elkosh. At the intersection of Routes 89 and 8944, about a kilometer south of Elkosh, the trail on Nahal Kaziv starts again. There is a gap in the trail following Nahal Kaziv from Ein Zev to Ein Tabat because that section of the Nahal is a wildlife sanctuary.
Continue following Kaziv until it forks at the intersection of an unmarked road. Follow the eastern trail. This is Nahal Neriya. Nahal Neriya will take you to the base of Mount Meron. At this point, there is a campsite under the jurisdiction of the Nature and Parks Authority.
From this point on you will be following the Israel National Trail.
Start the day with a short, intense climb to the top of Mount Meron. Meron is the second highest peak in Israel. On a clear day you can see all the way to Lebanon.
After hiking up and over Meron you will be on Nahal Meron which quickly connects to 6 Nahal Amud.
Once on Nahal Amud you can decide if you want to walk up the ridge into the city of Safed to spend the night, or continue down Nahal Amud for another few kilometers and stay in one of the two campsites on the eastern side of the Nahal.
Follow Nahal Amud until you reach the Sea of Galilee. This section of the trail running along Nahal Amud is very steep and dangerous. Be careful and take it slow. You will pass some ruins of pump stations built by the British before Israel was a state.
At the end of Nahal Amud the Israel National Trail will continue to Migdal. When you enter into a banana grove, stop following the Israel National Trail and walk to the east. You will see the Sea of Galilee and the town of Ginosar.
Sea to Sea is a very popular trip for Israelis. Generally, Israelis are open people. It is not uncommon to be offered a cup of coffee or to be joined for a meal while hiking on the trail. It is acceptable to camp in a farm; some of the trails even run right through them. The farmers do not mind as long as you are respectful of their land. The biggest threat to your trip will be the weather. Also, keep your distance from wild boars. They can be aggressive at defending their young.
Part of the trail passes close enough to the border with Lebanon as to theoretically be within the range of Hezbollah rockets. However, the situation in this conflict has been relatively calm since the 2006 war and it is unlikely that Hezbollah fires anything without any advance signs of escalation. The conflict in Syria is far enough away as to not be of any concern, but it might be if you head further eastwards to the Golan Heights.
Once you arrive at the Sea of Galilee you can take a bus to the destination of your choice. There are buses that run and have stops on Route 90 which runs along the shore of the Sea of Galilee. These can take you to Tel Aviv and Jerusalem. The alternative is to call a taxi and drive to Tiberias and take a bus to almost anywhere in the country. Be aware that buses do not run on Saturdays in Israel.
