All my blog posts about Dahab have some version of the word "Paradise" in them. I was there for 10 days in 2009 and could have stayed much longer. In fact, many visiting Westerners do. I met a dive shop attendant who came from Australia for a holiday and stayed for six months. This coastal down is considered to have access to some of the best dive spots in the world.
The seaside promenade is lined with seafood restaurants, hotels, dive shops, and chaise lounges. I could have gotten my SCUBA diving certification, but the coral reefs just beyond my chosen chaise were so gratuitous in underwater beauty that I rented a snorkel and paddled around.
