Mactaquac Provincial Park: The Complete Guide (Beaches, Trails, Golf and Camping)

Getting there and what you're walking into

Mactaquac is the big one: the provincial park most Fredericton families default to when they want a beach, a trail or a campsite without a real road trip. From downtown it is about 25 minutes west, roughly 25 km, out Route 105 along the north side of the river or via Route 2 (the Trans-Canada) with a short hop across. The park sits at 1256 Route 105 in Mactaquac, just upriver from the Mactaquac Dam that created the wide, lake-like stretch of water the whole park wraps around.

It is a large park, about 525 hectares, and it does not feel like a single destination so much as a cluster of them. The main day-use area with the beaches and picnic grounds is the part most people mean when they say "we went to Mactaquac." The golf course, campground and marinas are separate zones with their own entrances and their own rhythms. First-timers routinely underestimate how spread out it is, so it helps to decide before you go whether you are here to swim, to hike, to golf or to camp. Trying to do all four in an afternoon is a stretch.

The park is technically open January 1 to December 31, which is another way of saying it never fully closes. The beaches, campground and golf run on a summer season, but the gates, trails and winter facilities keep going straight through the cold months.

What you get for the drive is a lot of variety in one place: a proper swimming beach, a serious trail network, a championship golf course, a full campground, boat launches and an on-site restaurant and clubhouse. There is also a TreeGO aerial adventure course in the trees for families who want a bit of zip-line-and-obstacle adrenaline (it runs as its own paid attraction). That density is the whole appeal: for a lot of Fredericton households, Mactaquac is the default answer to "what do we do today?" precisely because it can be a swim, a walk, a round of golf or a weekend, depending on the mood.

The two beaches and swimming

Mactaquac has two supervised freshwater beaches on the headpond, and they are the single biggest reason people make the drive on a hot day. The water is calm, the drop-off is gentle, and there is a lot of shallow area, which is exactly what you want with small kids. Grassy, tree-shaded lawns run right up behind the sand, so you can plant a blanket in the shade and still keep an eye on the water.

Because it is a river headpond rather than the ocean, the water warms up nicely by mid-summer and there are no tides to time. That said, it is a lake fed by a river: on a windy day you can get chop and a bit of stirred-up colour, and after heavy rain the clarity drops. It is swimming, not snorkelling. Lifeguards are typically on duty in peak season, but hours vary and are never guaranteed, so watch your own kids as if there were no one else there.

The day-use area rounds out the swimming with picnic tables, shelters, washrooms, changehouses and playgrounds, which is what makes it work for a full afternoon rather than a quick dip. If you are weighing your options for a hot day, we compare it against the other local swimming holes in our guide to where to swim around Fredericton.

The trails: hike, bike and ski

The park's trail network is genuinely good and under-appreciated. The official park site lists 10 named trails threaded through the woods, and once you add the connectors, the golf-side loops and the groomed winter routes, you are looking at somewhere in the neighbourhood of 30 km to explore. Most of it is easy to moderate, well signed and forgiving for casual walkers.

The core loops follow a stream that starts in beaver ponds and drains toward the river near the marina, so you get a real cross-section of habitat: Beaver Pond (1.3 km), Alex Creek (2.2 km), Little Mactaquac Stream (2.4 km), Scotch Lake Road (2.4 km) and the short Porcupine Pass (0.3 km) among them, with a couple of moderate climbs up toward Murch Field for people who want to earn a view. Trails do close from time to time for maintenance or wildlife, so check the signboard at the trailhead.

Mountain bikers use much of the same network, and in winter the whole thing changes character: the park grooms a set of cross-country ski trails and keeps snowshoe routes open, with rental gear usually available on-site. There is even a forest skating trail and a duck-pond rink in a good freeze, which makes Mactaquac one of the more complete winter parks near the city.

Realistic expectations: this is river-valley terrain, not mountain terrain, so the hiking is more "pleasant woodland ramble" than "epic summit." The reward is easy access, good signage and a genuine sense of quiet once you are a few hundred metres from the beach. Wear real footwear after rain (the stream sections get muddy) and bring bug spray in spring and early summer. If you want more context on the wider area, see our Kingsclear and Mactaquac neighbourhood guide for what else is out this way.

The 18-hole golf course

Mactaquac Golf is an 18-hole championship course run inside the park, and it is one of the better-regarded public tracks in the Fredericton area, mature, tree-lined and with headpond views on several holes. It has its own clubhouse and pro shop and operates on its own season, roughly May 21 to October 18 in 2026, with tee times generally from early morning to early evening.

The 2026 rates (all subject to HST) run like this:

The twilight rate is the local's move: after 4 pm you can get most of a round in during summer's long evenings for a lot less. Carts and clubs cost extra, and prices can shift, so confirm current rates and book a tee time before you drive out. If you are course-shopping, we stack it up against the rest in our Fredericton golf guide.

The campground

The campground is large, with more than 300 sites, and it is the anchor of the whole operation. It runs a summer season, roughly mid-May into October, and offers everything from tents to big-rig full-hookup sites plus roofed accommodation for people who do not own gear.

Fees are split into a busy high season (the May long weekend and mid-June through early September) and a cheaper low season on the shoulders. All rates are subject to HST:

The honest trade-off: it is popular and it books up. Waterfront and prime sites go early for summer weekends, so reserve well ahead through the NB Parks reservation system if you have a date in mind. The upside is that being on-site means the beach, trails and golf are a short walk or drive, which is a real advantage with kids.

Boats, the marina and the headpond

Because Mactaquac wraps around a wide reservoir, it is a genuine boating park. There are two marinas here, the Mactaquac Power Boat Marina and the York Centennial Sailboat Marina, plus a boat launch for day trippers who tow their own. Seasonal moorings and dock space are offered through the park, and demand is steady, so call ahead if you want a slip for the summer.

The water itself is the Mactaquac headpond, the reservoir that formed when the dam went in during the late 1960s. It stretches roughly 100 km upriver, which gives you a big, open playground for powerboating, sailing, kayaking and fishing, far more room than the beach crowd ever suggests. On a calm morning the upper reaches feel more like a northern lake than a river.

A couple of practical notes: it is a working reservoir, so water levels can change and there can be debris after storms or high water, and the wind can build across the open stretches faster than you expect. Bring the usual boating sense, and if you are launching for the first time, scout the ramp before you commit the trailer.

The dam behind it all

None of this existed in its current form before 1968. The Mactaquac Generating Station, NB Power's largest hydro dam and the biggest in the Maritimes, was built across the Saint John River in the mid-1960s, and the flooding that created the headpond is what gave the park its beaches, its boating and its shoreline. The park was carved out at the same time as a kind of consolation and recreation prize for the valley that was reshaped.

There is a long-running plotline worth knowing: the dam's concrete has been slowly expanding because of a chemical reaction in the aggregate, which once put the whole station's future in doubt. After years of study, NB Power decided in 2016 to keep the dam and the headpond in place and rebuild the station to run to about 2068 rather than remove it. The short version for visitors: the lake stays. You may notice construction activity and staging around the dam over the coming years as that work ramps up, but the park and its water are not going anywhere.

If you want a closer look, the dam and its lookout make an easy add-on to a park visit, and the whole area is a natural stop on a west-of-the-city loop.

Fees, season, winter use and family tips

Here is the part people get wrong: day use at Mactaquac is free. Unlike some NB Parks that charge a vehicle permit, Mactaquac does not gate the beaches and picnic areas behind a day-use fee, so a swim, a hike or a picnic costs you nothing but gas and parking. The fees are for camping, golf and marina moorings (and the on-site TreeGO aerial adventure, which runs separately). Policies can change season to season, so if a fee matters to your plan, confirm it on the official park page before you go.

The park runs year round. Summer is beaches, golf and camping; winter turns it into one of the region's better spots for cross-country skiing, snowshoeing, fat biking and skating, with a groomed trail network and rental gear on-site. Fall is quietly excellent for walking the trails with the crowds gone.

A few family-tested tips:

• Pick your zone before you leave. Beach and golf and campground are far enough apart that you should choose your main activity and park accordingly.
• Go early or late on hot summer weekends. The beach lots fill and the shade goes fast; a late-afternoon arrival dodges both the crowd and the peak sun.
• Pack for a full day. There is food on-site (a restaurant and clubhouse), but a cooler, water and sunscreen save you money and hassle with kids.
• Bring bug spray in spring and early summer. The trails follow beaver ponds and streams, which is beautiful and buggy.
• Reserve camping early. Summer weekends and waterfront sites book out well ahead.
