The Avonlea lighthouse is one of the most memorable places/objects of Road to Avonlea. "The Sea Ghost" was the first episode that featured the lighthouse.

The Avonlea lighthouse stood on the crest of a hill in the middle of a field at the Avonlea Village Backlot near Uxbridge, Ontario with no ocean in sight. It was designed to resemble The Seacow Head Lighthouse on Prince Edward Island. The Seacow Head Lighthouse was used for wide shots (where you can see the cliffs) on Avonlea. The lighthouse built on the set in Uxbridge, Ontario was used for close ups.
