Birds, birds, birds. Cape St. Mary’s is a seabird reserve which is home to tons of different birds, including puffins. Unfortunately, we went in late September when most of the birds had already started to migrate south AND it was cold, windy and miserably rainy so we didn’t really get the whole bird experience. Anyway, we found a pullout on the side of the road that leads into the reserve that was quiet and away from the main interpretive centre. No facilities and no cell service but it’s an easy overnighter for a van or small RV. There were another couple turnouts along this road that could probably accommodate a bigger rig too. We weren’t sure at the time but after doing a bit of research, it seems like you’re ok to park for the night right in the parking lot by the interpretive centre as well.
Would only recommend staying one night here and come earlier in the summer if you want to get in some birding.
