Great dive site. Get there early, especially on Saturdays as parking is limited.
There is no diving there on Sundays and holidays.
Also the favored dive site is on the left side where there is a small walk way and a small rowboat by the waters edge thats the best entrance area L00K out for fisherman casting lines.http://www.waymarking.com/waymarks/WM69Y_Cape_Neddick_Nubble_Light_Maine
One of the most popular training sites in Maine , thanks to fairly calm conditions and shallow depths, Nubble Light in York Beach on Cape Neddick gets its name for the lighthouse perched on a close-to-the-mainland island. First illuminated in 1879, the Nubble Light lighthouse is now a local landmark. A protected cove calms water conditions at the dive site and entry is from a rocky shoreline. The dive itself is in and about the rock walls of the cove, and average depths of 20-40 feet (6-12 m) make it a good spot for new divers. Arrive early, as Nubble Light can get crowded. http://www.shorediving.com/Earth/USA_East/Maine/Nubble_Light/index.htm
