It rained for the first few days we were in NB. We made it to the beach about a week later.
The beach 15 minutes away is a provincial park in Cap-Pelé. It is shielded on one side by a sand dike and has a long and beautiful sandy beach that runs into the water for a few hundred metres that you can walk out to at low tide - perfect for little people.
Blaise kept himself busy with sand toys and Acadia slept. I didn't bring anything to do, so I burned - and I enjoyed it.
