Which city do you recommend on the seaside in Dagestan?
Consider Kaspiysk
Then it is better to consider Kaspiysk.
It is just more convenient from the airport of Kaspiysk, and if you have a small child, there is one very small beach, and attractions with water parks, by the way, there is one water park right in the arena area, free of charge if you do not use the facility. There are also attractions in Makhachkala, for example, Dragon Park.
And in Khazar, isn't it cleaned on the beach?
@Katerina: This is further than Derbent.
