You can take a look at my website for recent location photos, as well as some old ones dating back to 1980 when Sweetwater looked almost unchanged from OUATITW. http://www.ramon.btinternet.co.uk
McBain ranch now called Western Leone, very close to Mini Hollywood (El Paso set), many other locations very close. Location is North of the city of Almeria, you need to get on the Almeria - Granada motroway and head up to the Tabernas exit, Mini Hollywood, Western Leone and Texas Hollywood are all sign-posted when you exit the motorway.
For Flagstone, Cattle Corner and other railway locations you need to head up the Almeria - Granada motorway about 45 mins beyond the Mini Hollywood turn off to Estacion de la Calahorra ( south of Guadix). Drop me an email if there are any specific directions you need. The main Almeria - Granada railway line still exists the Estaction de la Calahorra railway station is the one used by Tuco & Wallace in GBU, now disused. Sadly the spur liine from Estacion de la Calahorra has been removed, this was used for numerous scenes including Cattle Corner and Tucumcari.
Remains of Flagstone are also at Estacion de la Calahorra. There are some big piles of what I guess is railway ballast stored piled up next to the line, try climbing up to the top to get a view towards the rear of the Flagstone saloon, you'll see the remains of the building with the big chimney that was always belching out black smoke in OUATITW.
Many of the other Leone locations are around Cabo De Gata area, North East of the city of ALmeria not far from the airport, i.e. Steven's farm, Ramirez mission, Shorty Larson hanging, Agua Caliente, Indio's hideout, Marisol's house, the list goes on.
A good place to stay is Hotel Alba in Los Albaricoques (Agua Caliente), a very friendly little hotel, great food and right in the heart of SW country.
Hope you have a good trip
