Four basic wooden tourist shelters provide accommodation inside the park. They have spring water but you need to carry a sleeping bag, food and cooking gear. You can also sleep at two ranger shelters (though they have no water), and there are 10 camping sites.
Some villages around the park's fringes have guesthouses, convenient for the beginning or end of some trails. They include Marelisi Guesthouse at Marelisi on the north side of the park, recommended for its excellent food; and the hospitable Nick & George Guesthouse at Atskuri, with good food and wine, and horses available for rides and treks.
The park spreads over 851 sq km of forested hills and alpine meadows up to 2642m high, north and west of Borjomi, and is crisscrossed by 10 marked walking and horse trails of various lengths. Diverse wildlife includes brown bears, wolves and chamois. The park is open all year but from about December to March/April there is snow in at least some areas (there are two snowshoe trails). Overnight accommodation is available at six basic shelters, and camping is possible too.
All visitors must obtain a permit beforehand from one of the two visitors centres – which are also very helpful for information and equipment rental. Several trails start at the Likani ranger station, 5km from the Borjomi visitors centre (about 6 GEL by taxi from Borjomi town). A good day-hike of 13km, with an ascent and descent of 800m, is Trail 6, which comes out on the Akhaltsikhe road at Qvabiskhevi. Trail 1 (Likani ranger station to Marelisi ranger station) is a 43km, three-day route crossing the park from south to north via Mt Lomis Mta (2198m). The longest and hardest route is Trail 2 (Atskuri to Marelisi), a 54km north–south route taking three or four days.
