Sinuiju (신의주시) is in Pyongan province in North Korea.
Sinuiju is the main border city with China on the Yalu river (which marks the border). The large Chinese city of Dandong is literally within walking distance over the bridge. Given that it represents the main trading and transportation hub between the two countries it is relatively easy to observe.
Sinuiju Station 📍 is an important stop between Pyongyang and Beijing.
Entry is theoretically possible by foot over the Sino-Korea Friendship Bridge 📍 from the Chinese border city of Dandong, although this option is mostly limited to Chinese citizens with appropriate visas.
A small Airport 📍 exists that sometimes takes flights from Pyongyang. The airport in Dandong over the border will have a more reliable schedule and more accessible connections.
A way "to get into" North Korea without actually passing border controls is to take an excursion boat from the Chinese city of Dandong. These boat are apparently allowed within a few metres of the coastline as long as nobody actually gets off.
Water quality has a poor reputation, with residents apparently purchasing Chinese bottled water from across the border.
