Park at the usual spot for climbing at duntelchaig. Probably the simplest thing to do is as soon as you cross the overflow of the loch, over the fence on the left and head for a big pine tree that's standing by itself around 200m away, straight a head. If you're not following the loch or the river, you've got a chance of going in the right direction! Once here drop down to a bog/stream and follow it up hill to the action (around 100m).
There's a steep wall with a terrible landing that looks maybe ok for short sport routes if the rock is solid underneath a load of flakey rubbish, a good steep boulder identified by a stream running underground, home of the Dagger and a couple of other things... Behind this is a good bouldering wall with grassy flat landing though it can be very boggy.
