The location

Where are we in Spain?

The site is in the north-eastern corner of Granada province in Andalucia, in a hamlet called Cuevas del Negro, close to the man-made freshwater lake Negratin. The villages of Benamaurel and Cortes de Baza are both around 8km (5 miles) away.
The nearest large town is Baza (pop. 20,000), around 18km south of here.
Coming in from the west, the view is dominated by a large granite outcrop known as El Jablacon. This rock rises to an altitude of 1500m above sea level, which is about 800m higher than the surrounding area. Considering that the rest of the landscape is flat, the view of El Jablacon is quite spectacular.

Granada airport is about 90 minutes drive to the west. Almeria and Alicante airports are about 2 hours south and east respectively.

The location is also about an hour's drive from the Sierra Nevada ski resorts.

Directions

My preferred route is to fly to Granada airport. Monarch do cheap flights from Gatwick and the airport is quite small, which makes retrieving your bags and checking in easy.

For car hire I prefer Crown, who are an affiliate of Monarch - you can book a reasonably cheap small car on the flight booking website. To get to their office, take the right-side exit from the airport terminal, to a small parking area. Crown run a minibus from there to their site, which is about a 5 minute drive away. You may well find there are other Brits waiting for the Crown minibus, too.

From the Crown office, you will pick up the A92 motorway, heading east. At the town of Guadix the motorway splits in two - one branch going down to Almeria while the rightmost 2 lanes, renamed the A92N, continues towards Murcia/Alicante. You must keep on the Murcia/Alicante branch.
About 90 minutes into the trip you will start to pick up exit signs for Baza. Be aware that there are 4 different exits for the town and it does matter which one you take. Your exit is marked Baza Centro and has the number 339 in the corner.

When you come to the end of the slip road, look for the large sign pointing left to Benamaurel and Castril. This map shows you where you are heading.
Benamaurel is the first village you come to, after about 15km on this road. Look out for the vicious speed bumps as you come into the village. Keep on the same road right through the village and out the other side. Go over the single lane bridge and look out for a left turn off the main road after about 200 metres. This is just before a bus shelter and bar (pub) on the left side of the road, if you pass these you've gone too far.

This small road has a speed limit sign of 40km/hr. Given how narrow and twisty this road is, you'll be lucky to get up to that speed.

From the start of this road, Cuevas del Negro is exactly 8km away.
One thing, if you zoom in on the ViaMichelin map (above), you won't see the side road featured. You have now made an important discovery about road maps of the spanish countryside.
