Ok. Read my posts here first, all are very recent, and all relate to saiga. The best place to see them is Askania Nova, in the Ukraine. When we went there, we flew to Kherson (some of us through Kiev, some of us through Istambul), spent the night, and the next morning we took a van (previously booked through an agency in Budapest, Hungary) to Askania Nova. Spent the remainder of the day in the reserve, spent the night at a hotel there, and went back to the reserve for more on the followig day. We left to Kherson at the end of the day. We were there with a group of zoo professionals, saw everything (the steppe, the zoo, the 100+ years old, artifically irrigated woodland, had an interpreter one of us arranged, and local guides. We also met the management. Great people. This was at the end of August. Summers are very hot there, so late summer/early autumn is best (or maybe the calving season in the spring). We had perfect weather. Since our visit was a 'pofessional' one, we clearly had more attention, than an average tourist. The Ukraine has a bad covid19 epidemic, so I'd wait until at least next year.
