Hwy 60 Corridor
The classic Algonquin experience — the string of drive-in campgrounds along Highway 60 between the West and East gates. This is where the long-weekend crunch lives.

How to get an Algonquin campsite when the corridor is booked
Algonquin is Ontario camping. Three hours from Toronto, the Highway 60 corridor's campgrounds absorb an astonishing share of the province's summer plans — and long weekends sell out within minutes of the 7 am release, five months ahead.
What most campers don't know is that Ontario Parks' own rules concentrate cancellations into a predictable window. Here's how the system works and how to use it.
Why Algonquin Provincial Park sells out
A short drive from most of Ontario's population, a finite corridor of drive-in campgrounds, and a season compressed into ten warm weekends: Canada Day, the August civic holiday, and Labour Day weekends are the toughest bookings in the province. Universities, camps, and cottage traditions all point the same direction at the same time.
How booking works on Ontario Parks
Reservations open five months before your arrival date at 7 am Eastern, one new day of inventory each morning.
Here's the quirk most campers miss: Ontario Parks bookings cannot be changed or cancelled more than four months before arrival. Every reservation made at the five-month release is locked for a month — which means a wave of them becomes cancellable exactly when the four-month mark rolls around.
Penalties then scale with how long the booking was held — from 10% of camping fees up to 50% — plus a cancellation fee starting at $8.50, so people who know they can't go tend to cancel sooner rather than later.
Ontario Parks has a “Notify Me” feature that emails you when a matching site frees up — no guarantee, and the same email goes to everyone watching.

The areas to know
Achray Campground / Sand Lake Gate
The quieter east side on Grand Lake — Tom Thomson country, and a favorite for campers dodging the corridor crowds.
Kiosk Campground
The remote northern outpost on Kioshkokwi Lake — small, paddle-oriented, and beloved by people who plan ahead.
Tea Lake Campground
A small corridor campground near the west end — modest facilities, big location value.

When cancellations actually happen
Ontario Parks bookings can't be changed or cancelled more than four months before arrival — so every reservation grabbed at the five-month release is locked for its first month. The moment your dates cross the four-month line, the entire pent-up backlog of changed plans becomes cancellable at once. If you're hunting a July long weekend, the four-month mark in March is when the board starts moving.
From there, penalties scale with how long a booking was held (10% of camping fees up to 50%), which nudges campers who know they can't go to cancel sooner rather than sitting on the reservation. The result: a burst at four months, then a steady trickle to arrival day.
The playbook
- Book at five months to the day, 7 am Eastern, with your gate and campground shortlist ready — long-weekend inventory doesn't survive the first minutes.
- Missed it? Set a free OpenCampsite alert immediately and make sure it's running before the four-month mark — that's when the locked-in reservations become cancellable and the first real wave of openings hits.
- Watch more than the corridor: Achray, Kiosk, and Tea Lake give the same park with less competition, and one alert can watch your dates across areas.
- Consider the shoulder: late June and September in Algonquin are spectacular (bugs down, loons loud), and mid-week dates return sites many times more often than Saturdays.
- When the email lands, book fast on the Ontario Parks site — and note their own Notify Me feature emails every watcher at once, so an around-the-clock scanner that catches the opening early is your edge.
Common questions
How far in advance can I book an Algonquin campsite?
Five months before arrival, opening at 7 am Eastern each morning on the Ontario Parks reservation system. Summer long weekends — Canada Day, the civic holiday, Labour Day — typically sell out at release.
Why do Algonquin cancellations start at exactly four months out?
Ontario Parks' rules bar any change or cancellation more than four months before arrival. Bookings made at the five-month release are therefore locked for a month, and when your dates cross the four-month line, the accumulated changed-plans backlog becomes cancellable all at once — the single best window for catching an opening.
Does Ontario Parks notify me when a site frees up?
It has a Notify Me feature that emails matching watchers — with no guarantee, and every watcher gets the same email simultaneously. OpenCampsite checks around the clock and emails you the moment a matching site appears, so you're not relying on winning that shared race.
Is the Algonquin alert free?
Yes — free while we're in beta, no credit card required. You book the site yourself on the Ontario Parks reservation system; we just make sure you know the instant it opens.
