no need to camp
Hi Vleis, good you're here!
Alex-Siwa is roughly 600 km, no need to sleep in between. The truth is many Egyptians fear the desert, although many never went. I find it fascinating, and quite puzzling. I get that look all the times from Egyptians, that look and the query whether I carry or not a firearm. Sure there are problems reported, mainly related to smuggling activities with Libya, but none that should be a concern from Alex to Siwa.
Once in Siwa, I recommend not to book with the first guide around, it's mainly a formality. It could very well be that others want to cross to Bahareya as well, and you'll be able to share costs. Ideally you could find a guy traveling back to Bahareya, the price could then become negotiable.
Do fill-up every time you can, in Marsa Matrouh for sure in case of shortage of fuel in Siwa. This has become a real bugger.
PM sent, let's talk soon!
