The Great Blue Hole is a large marine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape, 318 m (1,043 ft) across and 124 m (407 ft) deep. It has a surface area of 70,650 square metres (760,500 sq ft). It was formed during several phases of the Quaternary glaciation when sea levels were much lower.

2.5 hours from Ambergris. I think you can stay close to Blue Hole if that's your main focus. The normal reefs around there are incredible too. We stayed in Ambergris because the barrier reef was unbelievable, and the boats pick you up from your hotel.
