Banana island shouldnt be a problem, but would you want to? Huwar island - if your going from Qatar then you'll end up in a Bahrain jail as they dont belong to Qatar.

My top five camping locations

1) Sharaiwah island - about 50 miles offshore very isolated, fantastic place.

2) Fuwarait beach - great for snorkelling etc.

3) Ras Rakkan island - possible to get to on foot for the hardcore people - or buy a lit fomr Al-Shammal harbour

4) Umm Tais - easier to get to than 3), land cruisers a slight possibility

5) Zekreet - becoming more popular - 3 years ago no real tents there.......
