Borjomi (ბორჯომი bohr-joh-mee) is a town in central Georgia as well as the name of a natural reserve and of the famous volcanic salty spring water. The source of this spring water lies in the Borjomi gorge.
From Batumi it is possible to take a train to Khashuri. Once in Khashuri you have to travel down the road a bit to a market on the edge of town, where you can find marshrutkas going to Borjomi. The marshrutka ride from Khashuri to Borjomi is about 20 minutes.
In Tbilisi minibuses to Borjomi depart from an area in front of Didube metro station. The price is 8 GEL and the journey takes about two hours. It is difficult to get a front seat as some of the drivers give them away to good-looking girls and become very aggressive if you insist on first-come first-choice. It is possible to be dropped off in front of the tourist office in central Borjomi 'near the bridge of beauty'. Just ask.
Marshrutkas go from the main bus station in Batumi to Borjomi and vice-verse. The ride is about 3 hours.
The town is small enough to get around on foot. It is possible to get to the entry/exit points of the national park by marshrutka (e.g.cost to Likani is 0,40 GEL). Expect to pay 10 to 12 times more if you take a taxi, which of course is more convenient. If you are two or more persons you can share the cost of a taxi. For this purpose a good place to hook up with other travelers who want to visit the park is the National Park office where people have to go anyway to register. Best time is 9 AM.
Visit the city park. Stretched along the Borjomula river, the city park contains the source of Borjomi mineral water. The first part of the park contains park amusements and cafes. The rear part of the park is a great for a walk. If you continue past the asphalted part for another 2.5 km, you will reach hot springs that is reconstructing now (june 2015) but it is available at the same time and you can swim at a small pool and get rest. Few another pools are almost ready and would be open soon. Anyway the outstanding beauty of the nature around it will definitely make up for this. Near the entrance there is an option to use cable car to get up to plateau. The view over Borjomi is fantastic. edit
Visit the Borjomi Kharagauli national park. The largest national park in Georgia  by going to the administration of the office, which is a bit to the west of Borjomi (23 Meskheti str.), and get a free access permission (ID card or passport is no needed) and a map of the area with all the routes and shelters as well. If you want to take a hike in the national park, get enough supplies, water, and some basic sleeping gear with you, as the cabins are very basic (it costs 10 GEL). It also takes a one day hike from Borjomi to Qvabiskhevi (or the other way around) and then you can hitchhike or take a local bus or taxi back to Borjomi. It is also possible to take multiple day hikes. That way you get to go to the higher parts (up to 2600 meters). edit
The Green Monastery - An ancient monastery just outside of town. Walk, hitchhike, or bargain with a taxi to take you there (it isn't far, 10 laris should do it for a return trip). A short hike through the woods will bring you to the monastery. Very small, but beautiful.
If you prepare your own meals, be aware that none of the local supermarkets sell fresh vegetables and fruit. You have to get these at the market or at stalls in the street (closed after dark).
Taverna: Restaurant near the entrance of the main bridge (Silamazis Khidi) and the small park (patara parki), Taverna has a wide selection of traditional Georgian dishes. Taverna enjoys a reputation for its mushrooms cooked in clayware.
Imereti: Nice restaurant near the train station of Borjomi. When you exit the station, turn left and continue to walk the street until its very end. On the left you will find this restaurant which offers shashlik and a number of tasty Georgian dishes.
Fast Food: Near the central bus station on Rustaveli. It is more like a small buffet restaurant with cheap, reasonable quality food. E.g. try fish (from the river) with mashed potatoes and vegetable salad for 3,5 GEL.
There are lots of low budget options for staying overnight in Borjomi. Especially in the low season the prices come down. Information is available at the tourist office. They have more than 300 apartments and rooms to rent. A room with attached kitchen and bathroom with wifi in central Borjomi cost 15 GEL per night (mid October 2014). Be aware that during the summer season there are many unreliable so-called makler (intermediaries) active. They promise one thing, but deliver another. It is better to use the tourist office (free of charge mediation). If you have complaints you have a place to report to. They are effective.
