A campsite from a "couple of years back" (about 23 years ago @Artemus ), when I tent camped the last time. On an island halfway between Egypt and Saudi Arabia in the Red Sea. We each had 1 red jerry tank with fresh water to wash ourselves with-for the week. Scuba diving was superb, hiking not so much, you could probably walk from one end of the island to the other in a few minutes. The food was really shitty and we were very hungry all week. We did end up doing some (illegal) fishing and we cooked a big fish one day. Probably the best fish I ever had, but again, I was hungry.
This photo was taken from the light house. The "big" island (1 of 2) had a few Egyptian "coast guard" guys living there permanently. The year after you could only visit the area on luxury 'liveaboards' and the number of dives were restricted.
