May Long Weekend 2026 in the Canadian Rockies: Which Banff and Kananaskis Campgrounds Are Actually Open
Most Calgarians checking the camping plan on the morning of April 21 assume every Banff campground is still closed. Several aren’t. A handful more open in the 25 days between now and Victoria Day.
Here’s what’s actually open for May 16–18, 2026, what kind of trailer you need to camp in it comfortably, and what to do if you don’t own a truck.
Which Banff National Park campgrounds are open for May long weekend 2026?
Three are open right now, three more come online before the long weekend, and one lags until the weekend after.
Open year-round (available today, available May 16):
- Tunnel Mountain Village II — 188 sites, 5 km from Banff townsite, electrical hookups, running water through the cold months. The single best shoulder-season base in the park.
- Lake Louise Trailer — 1 km from Lake Louise village. Electrical hookups, well-drained gravel pads that handle late-April runoff without turning to soup.
- Mosquito Creek — 24 km north of Lake Louise on Highway 93 N. Smaller, quieter, no hookups — only take a rig with on-board heat and power.
Opening before May 16:
- Johnston Canyon Campground — opens May 1, 2026. $22/night. Front-country favourite; fills fast once reservations go live.
- Two Jack Lakeside oTentik — opens May 8, 2026. Glamping cabin, not a trailer site — worth noting if a larger group splits between cabin and RV.
- Bow River Campground — opens May 14, 2026, two days before the long weekend. $34/night. Hot showers and flush toilets — the upgrade pick if Tunnel Mountain is booked.
Not yet open May 16 weekend:
- Two Jack Lake oTentik — opens May 22
- Most unserviced tent loops across the park — mid-to-late May depending on snowpack
Do not wait. CBC and Global News have reported the same story every year: Alberta Parks and Parks Canada long-weekend sites are close to fully booked, and the people who didn’t lock in reservations during the February release window are usually out. The live window now is cancellations.
Is Bow Valley Provincial Park open in April 2026?
Yes. Power/Water, Tent Only, and Unserviced sites at Bow Valley Provincial Park have been open since April 4, 2026. If you want to camp this coming weekend — not the long weekend, this weekend — Bow Valley is the closest open provincial campground to Calgary, about an hour west on Highway 1.
A few Kananaskis notes worth having:
- Peter Lougheed / Interlakes reservations opened March 30 on a 90-day rolling window, so long-weekend dates are already live if someone cancels.
- Our pick for late-April nights in Bow Valley is the Willow Rock loop — the terrain funnels wind off the valley and those sites drain better than the lower loops when the ground is still half-frozen.
- Most other Kananaskis backcountry and tent-heavy loops stay closed until mid-May.
Can you actually camp in a travel trailer before Victoria Day?
Yes — in the right trailer. Wrong trailer, and you’re buying a repair bill.
The problem isn’t the cold air. It’s what the cold does to a trailer’s water system. Exposed water lines, dump valves, and holding tanks freeze below zero, and the morning after the first -5°C night you’re looking at cracked fittings, a stuck grey valve, or a fresh-water pump that won’t prime.
This is the real distinction between our two trailers:
- 2019 KZ Connect — 3-season. Open underbelly, exposed tanks, exposed low-point drains. Built for summer and early fall. Run it below freezing and problems follow.
- 2020 Yetti — 4-season, sleeps up to 6. Enclosed insulated underbelly, heated tanks, propane furnace ducted to both the underbelly and the holding-tank compartment. Built for Alberta winter — the trailer most of our cold-weather bookings take because the plumbing doesn’t freeze overnight.
On the -8°C nights we’ve sat out at Tunnel Mountain in mid-April, the Yetti’s furnace cycled roughly every 40 minutes off a 30 lb propane cylinder and the tanks stayed above freezing. A 3-season trailer on the same loop that night had a frozen black valve by morning.
Our working rule for customers before May 22 or so:
- Forecast lows below 0°C? Take the Yetti. Not optional.
- Forecast lows above 0°C every night? Either trailer works — the KZ Connect is built for exactly that range.
Check Environment Canada’s Banff forecast the day before pickup. Campground base elevation runs 4 to 6°C colder overnight than what Calgary sees — that’s the number that matters, not the city forecast.
What if I don’t own a truck to tow an RV in Calgary?
A Volvo XC60’s 3,500 lb tow rating is under the loaded weight of either trailer (the Yetti is 5,875 lb dry, closer to 6,800 lb loaded), and most crossover SUVs Calgarians drive daily won’t get close. Two paths:
Option A — You bring your own tow-capable truck. A half-ton pickup with a factory tow package and an integrated trailer brake controller handles either trailer. Book the trailer on RVezy and pick it up from our Calgary yard.
Option B — Yetti delivery. We tow the Yetti to your campsite, level it, hook up water and power, walk you through the systems, and come back at the end of your trip to retrieve it. You drive your own vehicle, or rent a smaller car, for the rest of the trip. Delivery range, fees, and availability are on the Yetti RVezy listing — that listing is the source of truth, and we keep the numbers current there rather than repeating them in blog copy that goes stale.
One thing specific to May long weekend: our delivery slots for May 16–18 book out before the trailer itself. If delivery is the plan, reserve the delivery window as soon as you lock in the trailer.
Not sure whether we deliver to the campground on your shortlist? RVezy lets you message us directly from the listing before you book — use the “Contact Host” button, tell us the campground and the nights, and we’ll confirm range and fee before you commit. This is a real difference between RVezy and Turo: on Turo the messaging channel only opens after a reservation is confirmed, so pre-booking questions have to go through RVezy.
Our picks for the next four weeks
- Now through May 14 (overnight lows still dipping below 0°C at elevation): Yetti with delivery, based at Tunnel Mountain Village II or the Willow Rock loop in Bow Valley.
- May 16–18 long weekend: Yetti at Bow River Campground if you can grab a cancellation (newly open, hot showers), otherwise Tunnel Mountain Village II’s year-round loop.
- May 22 onward (once overnight lows stay above freezing most nights): either trailer works. Compare the floor plans on the RVezy listings and pick whichever fits your group.
Book the trip
- 2020 Yetti — 4-season, sleeps up to 6, delivery available (RVezy) — pre-booking messages welcome. If you have questions about delivery range, cold-weather setup, or which campground fits the trailer, send them through the listing before you book.
- 2019 KZ Connect — 3-season, sleeps up to 10, summer/early fall pickup (RVezy) — bigger family bunkhouse with dual slide-outs; RVezy pre-booking messages are the right channel.
