Fall Colours Camping in Muskoka and Algonquin: Where You Can Still Get a Site

Every fall weekend, a lot of Toronto drives north on Highway 11 to see the leaves. On September 25 we checked every night from that day to October 24 at the parks those trips head for: Arrowhead and Six Mile Lake in Muskoka, Algonquin next door, and Killarney further north. We looked at car campgrounds, canoe routes and backpacking trails.

The main lesson isn’t “go midweek.” It’s that on fall Saturdays the kind of camping you choose matters more than the park you pick, and that after Thanksgiving an empty booking calendar usually means a campground has closed, not that it’s full.

Quick answer: On Saturday Oct 3 and Thanksgiving Saturday Oct 10, the car campgrounds in Algonquin (Highway 60), Arrowhead and Killarney together had zero open sites. On those same nights, 358 and 382 of Algonquin’s 420 interior canoe lakes still had permits, and Killarney’s interior had 69 and 77 open campsites. The one campground with Saturday space was Six Mile Lake, in south Muskoka off Highway 400: it has 71 sites you can book for all three nights of Thanksgiving. Hiking trails are tight at every park. After Thanksgiving, campgrounds start closing: most of Arrowhead shuts, and the part that stays open is full on the Oct 16–17 weekend, while Algonquin had 364 sites open that Saturday.

1. On a Saturday, choose the kind of camping first

On the first three Saturdays the car campgrounds are full. A handful of stray sites turned up in Algonquin (on the peak-colour Saturdays, only at Brent and Kiosk, which are hours from Highway 60), but that’s all. The interiors aren’t full. Killarney’s numbers are real numbered campsites, not lake permits, and they back up what the Algonquin lakes show: on Saturday Oct 3, about two in five of Killarney’s canoe sites could still be booked.

For a whole weekend on one booking:

If you car-camp, Six Mile Lake is the Saturday answer. It’s about 1.5 hours from Toronto, the closest of these parks. It isn’t a famous colour destination, but it’s Canadian Shield lakes and mixed forest at the south edge of Muskoka, and it’s the only campground here with real availability on peak Saturdays. Book it before Thanksgiving: it takes its last booking on the night of Monday Oct 12.

2. Inside the interior, avoid the famous lakes

The interior is open, but not the parts in the photos. In Algonquin, the one-portage lakes off the Highway 60 access points (Tom Thomson, Ragged, Rock, Pen) are full on both Sep 26 and Oct 3. Big Porcupine, one lake further, and Opeongo, where you can take the water taxi, had room on every Saturday we checked.

Killarney shows the same thing, even more clearly. On Saturday Oct 3, the lakes in the photos were all full:

The open sites are mostly on the north and east side of the park and out on Georgian Bay, not on the white-quartzite ridge lakes. That’s still Killarney in October. It just means a longer first day, or starting from a different access point.

3. Hikers have it hardest

At all three parks, the backpacking trails are tighter than the canoe routes on every weekend we checked:

Paddlers can move one lake over. Hikers can’t, because every trail campsite is on a single line. If you’re backpacking, plan for a Sunday-to-Tuesday trip. Highland had 5 to 18 sites open on every Sunday to Thursday night in the window.

4. The colour doesn’t peak everywhere at once, so neither should your plan

Ontario Parks' fall colour report put Algonquin at 50% colour change on Sep 24, Arrowhead at 20% on Sep 21 and Killarney at 10% on Sep 19. Historically, Algonquin’s Sugar Maples peak around Sep 27. The other parks are running later, which changes which weekend makes sense where:

• Algonquin, this weekend and Oct 3: peak colour, full campgrounds, open interior.
• Arrowhead and Killarney, Thanksgiving and after: probably closer to their peak then. Arrowhead’s campground is full on Thanksgiving, but Killarney’s George Lake campground has 51 sites on Saturday Oct 17 and 111 on Saturday Oct 24.
• Algonquin, Oct 16–18: past the maples, with tamaracks and aspens still to come, and the easiest weekend in the window: 364 sites on the Saturday and 321 you can hold for both nights.

5. After Thanksgiving, a blank calendar usually means “closed”

This is the pattern the booking pages hide, because a closed campground and a sold-out one look the same:

• Six Mile Lake takes its last booking on the night of Oct 12.
• Algonquin’s Pog & Kearney stops after Oct 11, and Canisbay and Rock & Raccoon after Oct 17. Lake of Two Rivers, Mew Lake, Brent, Kiosk and Achray are still bookable on Oct 24.
• Arrowhead closes 227 of its 364 sites after Thanksgiving. The 137 left were completely booked for Oct 16 and 17, the only fully booked campground in this whole check that weekend, while Algonquin next door had 364 open.
• Killarney’s canoe sites stop showing as bookable after Oct 18: from Oct 19 the reservation system returns every interior site as unavailable to reserve, not as open or full. We don’t know why, and it doesn’t mean you can just show up. Killarney’s own notes say that even in the winter season, stays have to be booked at least three days in advance. For a late-October canoe trip, call the park before planning around it.

The practical advice: for a late-October trip, check the season dates before you check availability. And don’t read “Arrowhead is full” as “Muskoka is full.” Less than an hour up the road, Algonquin had space.

How we know all this

This is two Campaid sweeps run on September 25: every night from Sep 25 to Oct 24, each queried on its own, across Algonquin (8 car campgrounds, 420 interior lakes, 3 backpacking trails), Arrowhead, Six Mile Lake and Killarney (George Lake, the canoe interior and La Cloche Silhouette). Checking one night at a time is what separates “full” from “closed,” and what shows a weekend you can book if you move camp once. Campaid does this for Ontario Parks, Parks Canada, BC Parks, Sépaq and more. Try it free.

Keep a few things in mind. The interior counts aren’t the same unit in both parks. Algonquin books by lake, and a lake counts as open if at least one party permit is left, while Killarney books numbered sites. So compare each park across weeks, not the two parks against each other. Only Arrowhead and Six Mile Lake are in the District of Muskoka, although Algonquin is where most “Muskoka fall colours” trips end up. And this is a single check: the Saturdays will keep filling, and cancellations will open a few sites here and there.

Frequently asked questions

Where can I camp in Muskoka for fall colours this weekend or at Thanksgiving? For a car campsite on a Saturday, Six Mile Lake is the one place we found real availability: 76 sites on Oct 3 and 71 bookable for all three Thanksgiving nights. Arrowhead and the Algonquin Highway 60 campgrounds were full on both Saturdays.

Is Algonquin sold out for fall colours? The campgrounds are sold out on Saturdays until Thanksgiving. The interior isn’t: 358 of 420 canoe lakes had permits on Saturday Oct 3. The lakes nearest the highway access points are the ones that fill, so plan to paddle one lake further.

Is Killarney full in October? George Lake campground was full on Oct 3 and Oct 10, but had 51 sites on Oct 17 and 111 on Oct 24. The canoe interior had 69 open sites on Oct 3, mostly away from the famous lakes near George Lake. In this week’s Ontario Parks colour report, Killarney was well behind Algonquin.

When do Muskoka and Algonquin campgrounds close for the season? In the booking system: Six Mile Lake after Oct 12, Algonquin’s Pog & Kearney after Oct 11, Canisbay and Rock & Raccoon after Oct 17, and most of Arrowhead after Thanksgiving. Lake of Two Rivers, Mew Lake and Killarney’s George Lake are still bookable on Oct 24.

Can I backpack in Algonquin or Killarney in the fall? On weekends it’s hard. The Highland Trail had 0 or 1 of 23 sites every Saturday, and La Cloche Silhouette had 1 to 5 of 34. Sunday to Thursday nights are much better.
