No. 2 Seoul

3 of 22

Annual Ridership: 2.5 billion

You might be tempted to visit Seoul simply to hang out underground—granted, with a lot of company. These subway cars make up for cramped quarters with high-tech amenities: cell phone reception, Wi-Fi, TVs, and heated seats. Each station has escalators and elevators as well as a dedicated arts space. Gyeongbokgung station displays historical artifacts from Korean dynasties throughout the ages. Another crowd-pleaser: fares that start at $1.
