Sulfur Baths
The bath district is called Abanotubani and is on the south side of the Metekhi bridge. It is easy to spot with its small domes on ground level. There are several small baths offering different levels of comfort. The baths are relatively small, and you may have to wait for a pool to become available. English service is not guaranteed. Massages are available; however, they are more like a washing, but well worth it for the experience. You should bring your own towel and beach sandals available for a small fee. Some travelers have suggested the Royal Baths is a much better alternative to Sulfur Baths they are next to each other. Sulfur baths tends to double the price at the end of the massage and bath in spite of your original agreed price. Also in other districts you can find sulphur baths. For example in the Kiev-ulica, A bit south east of metro station Marjanishvili, around the corner of hostel Green Stairs, there is an old, characteristic bath. In the evening you can get a private bath for 10 lari although they call them roubles and an additional towel is 2 GEL.
Turtle Lake (Kus Tba)
This lake is located in the hilly outskirts of Tbilisi. A popular weekend getaway for families, the lake offers pedal-boat rentals as well as swimming deckchairs optional for reasonable prices swimming entry, without deckchair, is about 3 Lari. Allright for a hot summer day, and offering views of both the mountains and the city below. Snackbars, restaurants and fruit cocktail shakers are available overlooking the lake. It's about an hour's pleasant walk from the Saburtalo district along country roads, passing the Ethnographical Museum, or a ten-to-fifteen minute 5-10 lari cab ride from the center. While the lake itself isn't particularly nice, the views from the hike up to the lake makes it a worthwhile excursion.
Lake Lisi(Lisis Tba)
Much further out than Turtle Lake a cab will set you back about 10-15 lari each way, Lake Lisi is much larger and more remote, with long, winding mountain walks surrounding the lake. Unlike Turtle Lake, the entire Lake Lisi is opened up for swimmers. Be warned - there aren't always taxis waiting to take you back...
Climb up to the Narikala Fortress
The crumbling ruins of this once-great fortress, standing alongside the Upper Betelmi Churches and the stunning Botanical gardens, offer panoramic views of the city below. But be warned - it's quite a steep climb - and while the lack of bureaucracy and guard-rails can be liberating for some, you may want to pay extra care to watch your step.
