Alton Bay Airport sits in Alton Bay, New Hampshire on the water at 504 ft MSL. This is a non-towered field with no land runways listed. The published traffic pattern altitude is not listed, so use the standard 1,000 ft AGL for light piston operations unless the current Chart Supplement says otherwise. There are no ILS approaches published. CTAF and UNICOM are both 122.8.

This airport is set up for seaplane and ice runway use. The published remarks say runway 01W/19W is plowed to about 2,600 feet in winter. Check NOTAMs for ice runway conditions before you go.

All seaplane takeoffs and landings must be north of the bandstand. Any travel south of the bandstand must stay at headway speed.

No on-field FBOs are listed. For seaplane parking and ice runway conditions, call the number in the Chart Supplement. For clearance delivery, contact Boston Approach at 603-594-5552. This is VFR only. A first-time pilot should plan for winter surface conditions, verify the active operating area and brief the bandstand and powerline references before arrival.
