Ahern State Park
Why dive here
With 35+ marine species recorded in the area - including nurse sharks - Ahern State Park offers some of New England's richest diving. Water ranges 4-19°C, warmest July, August, September.
Ahern State Park won't blow your fins off, but it’s a solid spot for getting wet when you’re in New England. With a maximum depth of 10 meters, it's pretty forgiving, making it ideal for newer divers or those knocking off some rust. We’ve found the main draw here is the peace and quiet; it’s not often crowded, so you can really take your time practicing buoyancy or just enjoying the submerged trees and the occasional freshwater fish darting past. Think of it as a pleasant, easy dive, perfect for a casual afternoon underwater.
