An annex to the island's national park, this interpretive center (open seasonally) offers a deeper explanation of the unique dune formations adjacent to St. Peters Bay. In addition to programs and displays, there are guided tours for individuals and groups. You can also take a cool break by making use of the beach, where supervised swimming is allowed from late June to the end of August. There are also bathrooms, changing facilities, showers, and an observation tower here. A visit here is worth a half-hour of your time to get oriented before plunging into the park. (Remember that entry to the dunes means entering the national park, which carries a summertime admission fee of C$7.80 per adult, C$6.80 per senior, and C$2.90 per child. All these rates are slashed by 50% during spring and fall.)
