Every place is worth visit culture wil be different in differnet places the food you eat wil be different. so offourse if u have the desier to travel there no places which is not worthy.
If you have been to Europe and Australia you should explore Russia some of my friends came back last month and i was really impressed with their trip and pictures.It must be a good experience
You would see a country with your own lens and afterall we all travel for having a vivid experience and a life that looks larger than us. You might come across an experience that will inspire you to share with all.
Happy Traveling.
