The crag is located two kilometers away from the edges of Bariay village and around 8km from the town of Rafael Freyre. 35 km away from the crag is the province capital-- Holguín with an International airport.
To get to the Los Portales crag from Holguín we need to take a local transport heading to Guardalavaca and get off at the crossroad heading to Rafael Freyre (21.022709, -75.987307). There are busses as well as shared taxis that can take you there from Holguin. After getting off at the crossroads, try to get a random transport heading to Bariay. Most likely you can find a horse carriage or a truck heading in that direction. Sometimes you may find yourself on a slow but pleasant ride on a cow carriage. The normal price for this distance is around 50-100 CUP. After you arrive at the Bariay village, you will see the Los Portales crag on the horizon. From there you need to walk around 30minutes to get to the wall.
A good solution might be to park or even stay overnight at Villa Negrito, located just a 20-minute walk from the main sector.
