Mount Carleton Provincial Park is reached from 7612 Route 385 near Saint-Quentin. NB Parks describes more than 17,000 ha, or 42,000 acres, of wilderness, Acadian woods, mountain peaks, campgrounds, heritage cabin sites, and seasonal park gates.
This is New Brunswick's big mountain park. The official page lists Mount Carleton at 820 m, or 2,690 ft, as the highest peak in the Maritimes, along with Mount Head, Mount Sagamook, and Mount Bailey. It also notes that the park has more wild animal species than any other part of the province, with at least 100 bird types, 30 mammal species, and rare plants such as Alpine blueberry and Bigelow's sedge.
Mount Carleton also has a night-sky identity. NB Parks says the park is designated a Dark Sky Preserve by the Royal Astronomical Society of Canada and is committed to reducing light pollution for star and planet gazing.
Camping ranges from four campgrounds to heritage cabins. The official page highlights Armstrong Campground, with 88 sites for trailers and tents, views of Nictau Lake and Mount Sagamook, a beach, washrooms, showers, kitchen shelter, and dump station.
NB Parks asks visitors to register at the Main Entrance upon arrival.
Plan around peak hikes, Nictau Lake views, camping, cabin stays, Williams Falls, winter visits, birding, wildlife watching, botany, and dark-sky viewing.
NB Parks lists 2026 gates from May 15 to October 31 and winter use from early January to late March. Confirm gate hours, seasonal closures, camping, cabins, trail conditions, weather, maps, and safety notices.
