The primary settlement in town, where 501 people resided at the 2010 census, is defined by the U.S. Census Bureau as the Alton census-designated place (CDP) and is centered on the intersection of New Hampshire Route 11 and New Hampshire Route 140. The town also includes the village of Alton Bay, a long-time resort located beside Lake Winnipesaukee.
Originally called "New Durham Gore"  because of rocky upland areas, or "gores", the town was settled in 1770, mainly by farmers because the highland areas provided less frost. Merchants then filled the lowlands. Early Alton history recounts stories of the merchants trying to convince the farmers to incorporate. They would succeed on 15 January 1796,  when the community was named after Alton, a small market town in Hampshire, England. 
Alton was part of Strafford County until Belknap County was erected on 22 December 1840.  By 1840, the village of Alton existed at the town's center. In 1847, the Cochecho Railroad began bringing passengers and freight to Alton Village and Alton Bay. By 1859, the town had two gristmills, seven sawmills, and five shoe factories.  But the most famous business was the Rockwell Clough Company, established by William Rockwell Clough, inventor of the corkscrew. By 1903, his company was producing 30 million corkscrews worldwide. 
Since the mid-19th century, however, tourism has been the principal business. In 1863, an Adventist group held a camp meeting at Alton Bay, which was the terminus of the Dover and Winnipiseogee Railroad.  That was incorporated as the Alton Bay Camp Meeting Association (now known as Alton Bay Christian Conference Center) in 1876.  In 1872, the Boston & Maine Railroad launched at Alton Bay the steamer Mount Washington, the first side-wheeler and largest vessel on Lake Winnipesaukee. When destroyed by fire in 1939, a replacement ship was found, also christened Mount Washington. Today, it continues to carry summer tourists between stops on the lake. The railway survived until 1935, and the old station at Alton Bay is now a community center. 
According to the United States Census Bureau, the town has a total area of 82.2 square miles (212.9 km2), of which 62.9 square miles (162.9 km2) is land and 19.3 square miles (50.0 km2) is water, comprising 23.49% of the town.  Alton is located at the southern end of Lake Winnipesaukee, around the 4-mile-long (6.4 km) inlet known as Alton Bay. The village of Alton Bay is located at the southern tip of the bay, while the main village of Alton is located 1 mile (1.6 km) farther south. The town is drained by the Merrymeeting River, the main inlet to Alton Bay. Mount Major, in Mount Major State Forest, has an elevation of 1,780 feet (540 m) above sea level. Popular with hikers, the summit offers unsurpassed views of Lake Winnipesaukee. The highest point in Alton is the north peak of Straightback Mountain, at 1,910 ft (580 m), just west of Mount Major. Both mountains are part of the Belknap Mountains range. Alton lies almost fully within the Merrimack River watershed, though a tiny corner is in the Piscataqua River (coastal) watershed. 
The town is served by five state highways. New Hampshire Route 11 passes through the center of town, leading northwest along the shore of Lake Winnipesaukee to Gilford and thence to Laconia, and southeast to Rochester. New Hampshire Route 28 also passes through the center of town, leading north to Wolfeboro and south to Pittsfield and Manchester. New Hampshire Route 140 leads from Alton west to Gilmanton and Tilton. New Hampshire Route 11A leaves NH 11 in West Alton and goes west into Gilford, and New Hampshire Route 28A forms an alternate route north from Alton Bay to NH 28.
