From Ballinasloe to Drumshanbo part 6: "Endless Road" At the site of the former Rockingham Estate, we discover a verdant fairyland in its miniature waterways network. Farther on, past the breeding grounds of Atlantic Salmon and homes of sea eels, we find a canal restoration project that promises to bring new vitality to an ancient tradition. Finally, we pass Drumshanbo and on to Acres Lake, marking the northern limits of navigation of the River Shannon.
