There are two options here - go and visit the Shanhaiguan Pass/Beidaihe area in winter, and see the Bohai Sea FROZEN over (you can even walk on it), or go in summer when the atmosphere is resort-style and quite electric! The only drawback is that in winter, it's cold, and there are VERY few tourists around. The majority of the restaurants and tourist shops are closed - and I mean REALLY closed. Most businesses are only open for three months per year, so just beware of that.
