About Tyuleny Archipelago
The Tyuleny Archipelago is a small group of islands in the Caspian Sea off the coast of Kazakhstan’s Mangystau Region, known for its marine wildlife. The islands are largely uninhabited and are recognized for their colonies of seals and seabirds.
The archipelago consists of a main island and several smaller islets and rocky outcrops used by breeding seabirds and by Caspian seals. Because of their ecological role the islands are primarily of interest to researchers and nature observers.
Human use of the islands has historically been limited; contemporary visits tend to be for scientific study, conservation or tightly controlled wildlife observation. Facilities are minimal or absent and landings are often regulated.
Geographically the islands sit in the northern Caspian Sea off Kazakhstan’s western shore within Mangystau Region, emerging from shallow continental shelf waters along the coast.
- Wildlife importance: Named after the Russian word for ‘seal’, the archipelago is notable for significant Caspian seal and seabird populations and is important for regional marine biodiversity.
- Access restrictions: Access is restricted in places and the islands are largely uninhabited; visits commonly require permits and are primarily for research or regulated nature study.
What to See#
- Tyuleny (principal island): A principal island within the group that supports large breeding colonies of seals and seabirds.

How to Get to Tyuleny Archipelago
The Tyuleny Archipelago in the Caspian Sea is offshore from Kazakhstan’s Mangystau coast and has no regular passenger service. Access is by private boat or charter from coastal ports such as Aktau or smaller fishing harbors on the Mangystau coast; expect a sea crossing and to arrange permissions in advance.
There are no public road links to the islands; plan transport from Aktau (the nearest major port) by hiring a licensed boat operator or joining an organized expedition.
Tips for Visiting Tyuleny Archipelago
- The Tyuleny Archipelago is remote and best reached by private or charter boat from the Mangystau coast (Aktau is the usual departure point); plan for a full‑day trip and expect basic landing facilities.
- Visit in late spring-summer for seabird and seal activity and use binoculars from the boat - much of the wildlife is best observed from a respectful distance to avoid disturbing colonies.
- Confirm local access rules before you go: islands in the Caspian can be protected or subject to seasonal restrictions, so check with regional authorities or local operators in Mangystau.
