Take Blackman Road from the Earnscleugh to Clyde road 7.4km south of Clyde. Go to end and find Fraser Dam Road. Follow your nose 13kms to the dam, well worth the trip. Latter sections are dirt so best done in dry weather or wet if you are up for a challenge. There are lots of routes that have been driven off the road formation by 4wds and bikes. I was told these are not popular with the farmer.
