Artemare can be reached from Virieu-le-Grand or Culoz. Head towards the village of Cerveyrieu (west) and park after the cemetery, near the pétanque court.
(S/E) From the car park, continue towards the village of Cerveyrieu, cross the small bridge over the Groin and take the small street on the left immediately after. Turn left again towards the Vaugrais campsite. Take the Chemin du Vaugrais (or Vau Grès) on the right bank of the Séran. When it turns right, continue along the river on Chemin des Carraz and join a wood at the foot of a limestone hill (rock shelter). Continue south until you reach the CD 904 road.
(1) Take this road on the right, pass a lay-by and, after a few houses, turn right at the sign for Chemin du Fierloz (Fierlos on IGN). Go straight up and turn right until you reach a monument with a statue of the Virgin Mary, which marks the viewpoint at the top.
(2) Retrace your steps for 150 m and climb straight up north on a path that rises through the sharp limestone pavement of Fierloz. The path veers left to follow a vague ridge line (a few cairns), crosses beautiful limestone slabs and eventually descends to the left (southwest) to rejoin the GRP®® trail.
(3) Take it on the right to descend gradually north-west to the Chemin de Belmont, where you turn right to join the Montée du Vaugrais.
Turn left (west) onto this carriageway and continue straight ahead until you reach a steep-sided stream. Turn right to enter Massignieu, cross the village from one end to the other and turn left.
(4) At the crossroads, turn right towards La Bavosière, descend to cross the Flon and climb up opposite into the forest until you reach the CD 30 at La Bavosière.
(5) Turn right onto the CD 30E and immediately take the path on the left that follows the right bank of the Séran. It rejoins the CD 30E before a bridge: cross the CD to reach the Cascade de Cerveyrieu waterfall opposite.
(6) After visiting, return to the bridge over the Séran, cross it and immediately turn left onto the path that climbs up the left bank of the river, below the CD 31, until you reach La Chaponnière.
(7) Cross the CD and take the Route de la Sablière opposite. Just after the last house, climb up the path on the left which passes a ridge and descends towards the Séran in the forest. Follow its left bank up to the Gorges de Turignin, which you reach by crossing the river.
(8) After exploring the site, take the path on the left bank and leave theGRP®® trail on your right to continue along the Séran until you reach a crossroads and a ford (rarely passable).
(9) 20 m before the ford, climb the Chemin Sur Montarfier to the south-east, which leaves the forest and joins the GRP®®. Continue straight ahead until you reach the CD 31 at a place called Gare de Vieu.
(10) Cross the CD31 and take the next road on the left (CD30). At the first crossroads, turn right towards Vieu and immediately climb up a rural path on the left that rises up a hillside before joining the CD 30d at the same level.
Turn left and immediately turn right onto Rue du Bac towards Vieu. Turn left towards the church.
(11) Take Rue du Boule on the right and go straight down a path that joins the edge of the hillside. It turns right and levels out, then becomes paved at En Cornillon. At the first house in Chongnes, go down a steep path on the left that leads to the Fontaine de la Doue and its chapel.
(12) Continue along Chemin de la Doue and, in Chongnes, turn left twice to go down Route de Vaux. Once you enter the forest, take the path that descends to the right and, at the next crossroads, descend to the right until you reach the resurgence of the Sources du Groin.
(13) Go back up to the crossroads to descend and cross the Arvrière.
(14) Go back up opposite in Vaux-Morets. Leave the Route de l'Arvière on your right and continue climbing opposite on the Route du Four, which turns right. When it turns left, take a level path opposite in the forest that cuts across to join the Route du Colombier (CD 69).
Go down it on the right and at the next crossroads, turn right to cross the village of Pont. At the bottom, go 50 m straight ahead over the bridge overlooking a deep canyon called the Groin: the Gouffre du Diable.
(15) Return to the junction and descend the Route de Champagne to the CD 31. Turn right, cross the bridge over the Groin and climb the Route de la Cascade for 300 m.
(16) Turn left onto Chemin du Golet au Loup, which descends southwards. It gradually turns right and descends beneath cliffs to the village of Cerveyrieu. Cross opposite to Place du Four.
(17) Continue straight ahead on Rue des Charrières. At the junction with Rue de la Cascade, turn left and head for the car park by the pétanque court. (S/E).
... not much signposting, but fairly easy to follow using the directions despite 2–3 potential mistakes (thanks again to the Visorando distance alert 
!!! ) and not very difficult.
