Its mostly a flat small country. Im living in the western side which is almost completly flat with some little hills like in video that are only in one place.
Southern region is better with high hills but never been there with motorcycle, will fix this with Tenere
From one side of country to next side is almost 200-400km. Depends where you start and go to next. We also have nice pine forests here.
