Dolmen de Crucuno is very easy to visit. It is situated adjacent to a house in the centre of Crucuno, a hamlet between Plouharnel and Erdeven. You can park 10m away from the monument. These facts don’t make Dolmen de Crucuno any less impressive when you are standing beside it. A giant capstone measuring c. 7.5m long and weighing an estimated 40 tons is supported by 9 large orthostats.

Take the Crucuno turn off the D781 at the Toul Siac’h roundabout. After c. 0.8km turn right into a car park in the centre of the village opposite the dolmen.

If you are near Carnac, Dolmens de Rondossec are a must-visit. There are three dolmens buried in a circular mound, measuring 20m in diameter, in the centre of Plouharnel. The dolmens run in parallel on a NNW-SSE axis.

The eastern dolmen is c. 13m in length with a northern chamber measuring c. 3m x 4m. The chamber is partially covered by a massive capstone. There is a small lateral chamber, west of the main chamber measuring c. 1m x 2m.

The central dolmen measures c. 11m in length. The covered passage measures c. 6m and the large chamber measures c. 5m long. It is covered by two massive capstones.

The western dolmen is much less impressive than the others. It is c. 8m long with a c. 5m covered passage and an inaccessible chamber measuring c. 3m x 2m.

Directions: From Carnac take the D781 towards Erdeven. Follow the D781 through two roundabouts in Plouharnel then turn left onto Rue Hoche to find the tumulus.

Dolmen de Kergazec is located c. 100m SE of Kergazec, a small village in Morbihan. The exposed dolmen is in reasonable condition, consisting of a large capstone on four supporting orthostats and dry walling. It retains a passage measuring c. 2m long. There is a small capstone on the SE end of the passage.

The best way to find Dolmen de Kergazec is to visit Dolmen de Kernevé then walk c. 150m SW along the C106 to the edge of an open field beside a house. Follow a dirt track heading NNW along the margin of the field for c. 300m to reach Dolmen de Kergazec.

Dolmen de Kernevé is located c. 10m down a path from Kernevé to Crucuno that starts c. 450m along the C106 from St Antoine roundabout on the D781. A large capstone and several orthostats have been incorporated into a garden wall. There is a convenient lay-by 20m NE of the path.

Dolmen de Kergazac can be found by walking c. 140m SW along the C106 to an open field. The dolmen is visible c. 300m NW from a track starting at the field edge.

Travel c. 1.8km along the C106 to reach Dolmen du Cosquer.

Dolmen du Cosquer was a relaxed start to the day. The small dolmen is by the roadside in Cosquer, a  hamlet c. 2km N of Plouharnel in Morbihan.

Follow the D781 for c. 2.2km from Plouharnel to the St Antoine roundabout. Take the first exit for C106 Kernevez. After c. 2.3km on this road you will reach Dolmen du Cosquer.

Allée couverte de Mané Roullarde is located in a private residential area off Rue de Kerisper in Trinité-sur-Mer in Morbihan. It is still an impressive monument despite its ruinous state. The site has been fenced off to protect the site and discourage visitors. The c. 20m long passage retains four capstones and some inaccessible carved stones. The elevated position of Allée couverte de Mané Roullarde on a promontory would have yielded extensive sea views.

In the centre of Trinité-sur-Mer take the D781 Locmariaquer exit off the Alain Barriere Roundabout. After c. 50m bear left onto Rue de Kerisper. Follow this road for c. 150m to reach a private residential lane on the left. Park up as close as possible. Walk c. 150m up the lane to Allée couverte de Mané Roullarde on the right.

Dolmen de Kermarquer is located c. 100m NW of Kermarquer, a small village in Morbihan. The circular mound, which measures c. 25m in diameter and 1.5m high, contains a dolmen with an unusual double chamber. A passage running ESE for c. 3m has two large capstones. It leads to a main chamber, open to the sky, measuring c. 2.5m square. A lateral chamber, separated by two portal stones, is located S of the main chamber. This subsidiary chamber, measuring c. 1.3m square, retains one capstone.

Take the turn for Kerdeneven off the D186 in Kermarquer. Bear right at a fork after 110m. Continue on this narrow lane for c. 70m to reach a wooden sign for a path to Dolmen de Kermarquer on the right. It is possible to park on the grass verge close to the path. Follow the path NE through the woods for 100m to reach Dolmen de Kermarquer in a clearing.

Dolmen de Kervilor Mané-Bras is located c. 250m N of Kermarquer, a small village in Morbihan. It consists of a sub-circular mound, measuring c. 30m in diameter, with three dolmens therein. There are two central dolmens with partially covered passages. Dolmen North-Central has a c. 5m passage running from ESE towards a square chamber measuring c. 3m. There is one capstone on the W end of the chamber. The South-Central dolmen has a c. 6m passage running ESE towards a sub-circular chamber measuring c. 3.5m in diameter. There is a large capstone on the junction of the chamber with the passage. Viewed from the E, these dolmen give the mound a pleasing symmetry. It is for that reason that I considered the dolmen on the S edge to be a later addition. Also, it is a simpler construction than the central Dolmens. Dolmen South has a c. 3m passage running SE towards an irregular quadrilateral chamber measuring c. 2m x 1.5m. There are no cover stones on Dolmen South.

I found Dolmen de Kervilor Mané-Bras by accident while looking for Dolmen de Kermarquer. I saw a wooden sign at 47.597594, -3.036248 on the roadside and followed the path through a wood for c. 200m to reach a large mound in a clearing.

Le Petit Ménec Alignments is a full stop E of the Carnac Alignments. The stone rows wind through a small wood. There is a more intimate atmosphere in this less frequented site than in the popular massive alignments.

At the E end of the D196 after visiting the Kerlescan Alignments turn left along the D186 towards Auray. After c. 300m take the 1st right for Keriolet. Stay on this road for c. 300m to reach a lay-by on the left. The path to Alignements de Petit-Ménec is on the right-hand side of the road.

The Quadrilataire de Manio is one of Carnac’s more enigmatic monuments. It is difficult to imagine how this stone rectangle would have fitted into the Carnac Complex. The proximity of the Geant du Manio merely adds to the air of mystery.
