A Syrian military post between 1948-1967. In that period the Syrian army would shell Israeli agricultural settlements in the valley below as part of border disputes. The post was conquered by Israel in a bloody battle in 1967. It is now the site of a memorial, and you can explore the Syrian bunkers, which have a great view down to the fields of the kibbutzim.
Tel Faher or Golani Lookout is a former Syrian military outpost in the Golan Heights that has been occupied by Israel since the Six-Day War in 1967.

Nimrod Castle, Kalaat Namrud
An ancient fortress in the northern Golan Heights, built in the 13th century by Muslim rulers to defend against a possible Crusader attack. It is located on a steep mountain ridge, with deep forested ravines on either side, and has a stupendous view of its surroundings. A trail leads from the fortress's west edge downhill several kilometres to Banias, another important historical and nature site in the area. Hike: ~2 hr.
Mount Hermon is Israel's highest mountain (2,284 m), home to the country's sole ski resort. There is snow for only part of the year (between mid-January and March), so check ahead. At other times, you can still visit and enjoy the views, the wildflowers, and so on at a much cheaper price. There is a cable car going up the mountain. Access is by private car - there is no public transportation within about 10 km of the ski site. The ski company offers bus trips from Tel Aviv to the ski site (call for details). Ski prices are about ₪200 for equipment rental and ₪200 for ski-pass.
A mountain in the eastern Golan Heights with an Israeli stronghold (formerly a Syrian stronghold) on top and views of Syria to the east and the Golan Heights to the west. On some days, you might hear or even see a bomb going off in the distance, part of the Syrian Civil War. From this distance, it sounds like thunder. You can explore the Syrian army bunkers here from before 1967.
Quneitra is a ghost town, which was abandoned by the Syrians during the 1967 war and left in the no-man's-land ever since. Thoroughly wrecked not only in 1967 but in the subsequent 1973 conflict as well, from the Israeli side, the area can only be viewed from designated viewpoints set up along the border road, as it's just across the de facto line of control.
There is no volcanic activity, but a nice park explaining different volcanic facts. The site includes art in the volcanic gravel.
