It was a part of our DMZ tour. Inside the tunnel has meeting room, family room, maternity ward, operation room, kitchen, storage and bathroom with ventilator. Pretty impressive. We went there in May. It was a very hot and humid day. Inside the tunnel we felt uncomfortable at the beginning with little air. But it's not claustrophobic. Sometimes the tunnel is narrow and tight. I slipped on the wet steps, but my husband caught me just in time and was unharmed. Need to crawl to avoid startling the centipedes and spiders. It was quite the experience.
