Visiting the sea caves in St. Martins, New Brunswick, is a funky, family-friendly adventure for a perfect afternoon by the Bay of Fundy.

The sea caves are one of the main (if not the main) attractions in the small coastal town of St. Martins. They are free to visit and are located at the far end of the village where you can easily spot them from the road. Park in the restaurant parking lot or leave your car by the side of the road, being careful not to block incoming traffic. 

Like most of the water-related activities by the Bay of Fundy, the caves are only accessible at low tide. Twice a day in St. Martins, the bay losses around 38 feet on a 500-meter surface, creating a humungous rocky beach. Parts of the beach stay wet and slippery, so be very careful while walking or climbing rocks. It could be a good idea to put on sandals or water shoes if you don't want to get your shoes wet. 

Start by visiting the first (and main) cave, right at the entrance of the beach. Most people stay around there and do not go exploring beyond the first two caves. If the tide has gone out almost entirely, you can then make your way around the rocks to access a hidden cove. You will discover a private beach and more caves with a fewer people. 

Think about checking the tide schedule before heading to the sea caves as it varies every day, and be sure to check for the upcoming tide: you don't want to be stuck with the bay rising in the alcove around the rocks. 

For another angle of the caves, or if you wish to visit at high tide, you could enroll in a day tour with a local kayak company in St. Martins.
