According to the Taynuilt village website you can wander freely around the nearby Bonawe Ironworks free out of season. In season you may be able to see enough without paying but it only costs £3 for a ticket. If you’re in the area at all, it would be a pity to miss it. A good alternative website is www.undiscoveredscotland.co.uk/taynuilt/bonawe.
