In Türkiye, there is no mandatory individual insurance that covers search and rescue costs. However, some private insurance companies may offer such coverage. For high-risk outdoor activities like mountaineering or trekking, if no insurance policy is in place and a search and rescue operation is required, the costs might be covered by the state or passed on to the participants. However, it is strongly recommended that individuals obtain personal insurance, especially when participating in international events.

Please note that this insurance does not replace the cancellation insurance or the other way around.
