There are many reputable companies now taking visitors into the DPRK. Do your research online and take the time to read feedback and comments from previous travellers. You will also need to ensure you have an acceptable passport and the right visas.
Prices vary considerably as do itineraries, there are also specialist packages for those with specific interests eg. aviation, railways etc.
Whatever company you decide to use or whichever tour you book, the protocols for visiting a country like the DPRK are the same. Ensure you are aware of the restrictions and expected behaviours before you book.
The Society is more than happy to offer information before you book or travel.
