Am I confused, or are there two Blue Hole's?

Yes, there are two sort of.
The Great Blue Hole at Lighthouse Reef
Like a giant pupil in a sea of turquoise, The Blue Hole is a perfectly circular limestone sinkhole more than 300 feet across and 412 feet deep. The array of bizarre stalactites and limestone formations which mould its walls seem to become more intricate and intense the deeper one dives. Near to The Blue Hole, one of Belize's largest protected areas, Half Moon Caye Natural Monument, encompasses 10,000 acres of the atoll and 15 square miles of surrounding waters.
The temperature in the Blue Hole at 130ft is about 76F with hardly any change throughout the year at that depth.
For all the practical purposes the over 400-foot depth makes the Blue Hole a bottomless pit. The walls are sheer from the surface until a depth of approximately 110 feet where you will begin to encounter stalactite formtions which actually angle back, allowing you to dive underneath monstrous overhangs. Hovering amongst the stalactites, you can't help but feel humbled by the knowledge that the massive formation before you once stood high and dry above the surface of the sea eons ago. The feeling is enhanced by the dizzying effect of nitrogen breathed at depths. The water is motionless and the visibility often approaches 200 feet as you break a very noticeable thermocline.
The Blue Hole National Park (http://AmbergrisCaye.com/pages/town/parkbluehole.html) is right next to the Hummingbird Highway. There are two access points, the visitor centre/parking area for Herman's Cave, and the lay-by just above the Blue Hole. The two are only a mile and a half apart. The National Park is just 12 miles southeast of Belmopan (on the right coming from that direction), and can easily be reached by bus. Tours also run from San Ignacio and Belize City. Exploring the park takes about half a day.
Back in geological time, the pool itself was a stretch of underground river cave, but it lost its cover when the roof collapsed. Since the Hummingbird Highway was built, it has been a favourite swimming spot, with refreshing cold water. If you have a snorkel, bring it so you can peer down into the eerie blue cavern where the water comes from. The strearn carries on about 40 yards before descending down a siphon through an echoing cave full of bats (and a few Cliff Swallows in the winter months), and later on re- emerges to join the Caves Branch River. If you're coming from Belmopan, you will already have driven over it. The surrounding limestone is full of caves, and it was only by tracing coloured dyes that it was ever discovered that this was the hydrological connection.
The park has a small trail network, particularly good for birding because the forest canopy is low. This Hummingbird Loop can be walked in an hour or longer for those wanting to linger and see more. As well as the trees. the rich forest contains a wealth of bromeliads, mosses and ferns. more visible than normal because of the steep lay of the land.
