From Gifford, you can walk to the castle by following the Gifford Water to the east. Alternatively, you can get there by taking the Castle Park Golf Club's perimeter path and keeping the Hopes Water to your right. The easiest (in my opinion) route starts from the B6355 opposite Danskine Loch, where a path follows the Gifford Water to the west. This path is one mile to the castle from the gated entrance on the B6355.
