Frenchman Côme Doerflinger runs adventure trips in the countryside adjoining Terelj through his outfit based in Gachuurt. He mainly runs horse treks, including all-inclusive multiday trips, but also has kayaks and canoes that you can use to float down Tuul Gol, and mountain bikes that are great for excursions up Gachuurt’s side valleys towards Terelj. There's also accommodation at his ger camp (T25,000 per person, meals from T6000).
