In 1851 the village became the terminus of the Cochecho Railroad from Dover, New Hampshire.[2] The rail line became the Lake Shore Railroad in 1890, continuing west to Lakeport in Laconia. It was in operation until 1935. The MS Mount Washington and its predecessor ships on Lake Winnipesaukee have made Alton Bay a stop since 1872.

Alton Bay is home to the Alton Bay Christian Conference Center, a Christian retreat center and campground organized in 1863 (as the Second Advent Camp Meeting and incorporated as the Alton Bay Camp Meeting Association in 1876). It continues its year-round ministry by hosting retreat groups, summer camps, concerts, speakers, and summer residents (who live there and participate in the services of the Association).[3]

The village has a separate ZIP code (03810) from the rest of the town of Alton.
