Collonges/Les Khmers is mainly one boulder located just next to the road. It offers many interesting line on a really quite and nice location.
The terrain is flat which makes it perfect for family day. This area is really exposed to the sun which make a perfection area for winter bouldering. It's definitely too warm in summer but it can always bit a nice place to sunbath.
The boulders "Daim" in the park aren't describe on this guidebook as it's forbidden to climb at the moment. You can walk to the Funambule with offer a really nice 7b (a bit morpho).
Recommandation:
Les Khmers verts, 7A
