How to Pack a Chevrolet Trax for a Day at Snake River Canyon
Behind the rear seat, the 2026 Chevy Trax gives you 25.6 cubic feet of cargo space. Sequence it right and that’s enough for a full canyon day. Chevrolet lists that number, and it’s genuinely generous for a subcompact SUV. But August at the Snake River Canyon means a cooler that eats a third of your cargo floor, adults in back who’d like to keep their knees, and gear that comes home wet and sandy. The question isn’t whether it fits. It’s what goes where, in what order, so nothing gets baked and nobody folds a seat they actually need.
Here’s exactly how we’d load it.

- Solo or duo? Keep both rear seats up. The 25.6 cu ft behind them handles a cooler, two daypacks, and a first-aid kit with room to spare.
- Bringing a bike? Fold one side of the 60/40 split rear bench. You keep one rear passenger seat and gain a flat rail for one bike. Commit to that layout before loading, not after the cooler is already in.
- Full crew of four? Daypacks move to laps or footwells. The cargo area holds the cooler and return gear only.
- Wet gear (water shoes, towels, river clothes)? Pack them in a dry bag, load it last and flat on top of the cooler, so it slides straight out when you reach Centennial Waterfront Park.
- No roof rack needed for the Canyon Rim Trail. The trail is fully paved. A bike fits flat with one seat folded.
What Actually Matters When You’re Loading the Trax for the Canyon?
Three variables decide almost everything here, and they are how many seats are occupied, whether you’re biking or hiking the rim, and how hot the day is going to run. Get those three right and the Trax cargo layout handles the rest on its own.
| Your Setup | Rear Seats | Best For | Key Spec | Honest Tradeoff |
|---|---|---|---|---|
| Rim hike, 2 adults | Both up | Lightweight day | 25.6 cu ft cargo floor | Cooler fits upright; room to spare |
| Rim hike, 4 adults | Both up | Full crew | 25.6 cu ft cargo floor | Daypacks shift to footwells or laps |
| Bike carry, 1 passenger | One side folded | Rack-free bike haul | Partial fold, ~40 cu ft | Lose one rear seat; bike loads before the cooler |
| Two bikes, no rear passengers | Both folded | Gear-only run | 54.1 cu ft flat floor | Front seats only; plenty for two adults |
| Kayak or zip-line day | Both up | River activities | 25.6 cu ft + footwells | Add a dry bag per person; load them last |
The 2026 Trax is front-wheel drive only, and that’s worth saying plainly. Anyone wondering whether the ACTIV trim unlocks AWD for the canyon (it doesn’t) should know that the canyon access roads to Centennial Waterfront Park and the Shoshone Falls lot are paved, and the Canyon Rim Trail is fully paved, so FWD handles this day without issue. If your destination shifts to unpaved terrain, that’s when a conversation about the Chevy Trailblazer (which does offer AWD) makes sense.
The Cooler Is Your Anchor. Build Everything Else Around It.
On a late-August day at the canyon, the cooler is your anchor and everything else gets built around it, because temperatures in the Magic Valley push toward the mid-90s and the rim runs short on shade, so cold storage earns priority. It goes in first and comes out last, planted flat against the rear liftgate before anything else gets loaded. The cooler is not optional.

With the cooler against the liftgate, you’ve got a clear lane from the tailgate to the back of the rear seats. Daypacks stack vertically against the seat-backs rather than on top of the cooler, where they’d absorb heat and block your view out the rear glass. Hiking poles slide horizontally between the cooler and the side wall. They lie flat without a cargo net and won’t roll on the descent into the canyon along US-93.
Schedule a service check before your canyon trip
One thing we notice loading the Trax at the lot is how low the cargo floor sits relative to bumper height, so you’re sliding the cooler in straight rather than hoisting it over a high lip. That’s a practical advantage first thing in the morning, and a real one at the end of a long canyon day when the cooler is still full of ice water.
Match the Gear to How You’re Actually Using the Canyon
How you pack depends on which part of the canyon you’re using, since the Canyon Rim Trail runs more than 10 paved miles along the Snake River gorge, with trailhead access from the Twin Falls Visitor Center and from Shoshone Falls Park. What you bring, and how you stage it in the Trax, shifts with the plan.
Walking or jogging the rim. Both seats stay up. Chevrolet’s 25.6 cubic feet behind the rear bench swallows a 48-quart cooler, two 20-liter daypacks, a first-aid kit, and a change of clothes without any creative stacking. You’ll still have room for a folding camp chair at an overlook.
Biking the rim. Fold the passenger side of the rear bench (the larger portion of the 60/40 split). One adult rides rear driver’s-side; the bike frame lays flat on the folded side with the front wheel removed. That works cleanly. Fold both sides and you get 54.1 cubic feet (enough for two bikes), but you’re down to two front seats. Your call, made before loading begins.
Hitting Centennial Waterfront Park for kayaking or the zip line. A dry bag and a change of clothes per person go in last, flat on top of everything else, so they’re the first things out at the park. The Trax’s flat cargo floor makes that layered loading intuitive rather than a puzzle at the tailgate.
One firm line to draw, and Chevrolet confirms the 2026 Trax carries no tow rating. A bike trailer or cargo trailer isn’t happening. If your canyon day involves a trailer, that’s a job for a Chevy Colorado or a truck in the Silverado lineup (properly equipped and rated for the load). The Trax is the right tool for a rim-trail day. A truck is the right tool when you’re towing something behind you.

Frequently Asked Questions
Can the 2026 Trax comfortably carry four adults and canyon gear on the same trip?
Yes, with realistic expectations. With all four seats occupied, you’re working with 25.6 cubic feet of cargo space behind the rear bench. That handles a shared cooler and a modest pile of daypacks. It’s not enough for a bike or oversized gear when the seats are all in use. The practical move: keep individual kit to one 20-liter daypack per person, use the cooler as the shared anchor, and let footwells and laps handle the overflow. The Trax seats five with 38.7 inches of rear legroom, so four adults ride comfortably. The cargo is where you do the editing, not the seating.
Does the ACTIV trim offer more cargo space or a terrain advantage for canyon roads?
The ACTIV adds real style (18-inch black aluminum wheels, a black grille with Titanium chrome accents, Yellow interior accents) but the cargo dimensions don’t change. Every 2026 Trax trim (LS through ACTIV) delivers the same 25.6 cubic feet with seats up and 54.1 cubic feet with the rear bench fully folded. No trim adds AWD. Every 2026 Trax runs front-wheel drive only, with 7.3 inches of ground clearance and no tow rating. For the paved Canyon Rim Trail and the paved canyon access roads, that’s all you need. The ACTIV is a style and comfort upgrade. For genuine off-road terrain, you’d want a different platform.
