Alpaca Caribou Pack Raft Review: A Real Boat That Packs Down to Backpack Size

Introduction

Most backpacking gear is a variation on something you already own. A pack raft is not. It is an actual inflatable boat that folds down small enough to carry on your back, and that one difference opens up routes that are simply not walkable.

The Alpaca Caribou is built by Alpaca, a company that manufactures its rafts in Colorado. It is designed as a single-person pack raft that breaks down into a compact bundle, weighs around 5 lb, and inflates using a large stuff sack in the same way you would inflate a sleeping pad. A roll-top cargo opening in the deck lets you stow gear inside the boat and keep it dry while you paddle, and a front attachment point is included specifically so a bike can be mounted on the bow.

In practice that combination changes trip planning more than any single specification. A route no longer has to end where the trail ends, and a loop no longer has to close on foot. For backpackers who have spent years covering ground one way, this is a genuinely different tool rather than a lighter version of an old one.

Who This Pack Raft Is For

The Caribou makes the most sense for people whose trips already involve long distances and remote terrain. Anyone who has looked at a map and noticed that a river runs in the direction they want to travel is the natural audience here, because the boat turns that river from an obstacle into a route.

Bikepackers are a particularly good fit. The front attachment point exists so a bike can be carried on the raft, which makes it possible to ride into an area, cross or descend a waterway, and continue riding. Trips that combine riding and floating become realistic rather than theoretical.

It also suits backpackers who want to reach country that has no trail through it. Multi-week traverses in remote ranges, where walking alone leaves large gaps in the route, are exactly the kind of objective a pack raft is meant to solve. The boat is not a replacement for hiking gear. It is an addition that extends where hiking gear can take you.

Main Strengths

The Caribou is impressive less because of any one feature and more because of how the whole package holds together. It is light enough to justify carrying, small enough to pack, and useful enough to change an itinerary.

Packed Size and Weight

Around 5 lb is a reasonable figure for a boat, and it matters most when you compare it against what the same weight buys you in other categories. The Caribou rolls down into a bundle that can be strapped to a pack rather than carried in hand, which is the difference between a piece of gear you bring and a piece of gear you leave behind.

The inflation system reinforces the same idea. Using a large stuff sack to fill the raft means one piece of equipment does double duty, so you are not adding a separate pump to an already heavy load. Set up and pack down stay quick enough to be repeated daily on a longer route.

Cargo Capacity and Dry Storage

The cargo hold is the feature that makes the Caribou practical rather than merely fun. A large zippered opening in the deck lets you load your pack and other gear inside the boat, which keeps weight low and centered while you paddle.

Just as importantly, that storage keeps your equipment dry. Water exposure is the main threat to sleeping bags, insulation, and electronics on any river trip, and putting gear inside the hull rather than on top of it removes a large part of that risk. You spend less energy protecting your load and more energy moving it.

Bike Mounting and Trip Potential

The front attachment point is what separates this model from a general-purpose pack raft. Mounting a bike on the bow is a specific design decision aimed at riders who want to link trails, gravel roads, and rivers into a single journey.

That capability is the reason a pack raft can be more than a novelty for a certain kind of trip. Instead of shuttling, you float. Instead of turning around, you continue. The gear does not just add a new activity, it removes a logistical wall that has always stood between bikepacking and water travel.

Things to Consider Before Buying

The Caribou is a significant purchase, and the honest framing is that it is expensive for what looks like a simple inflatable. That price reflects a specialized product made in small quantities, not a mass-market item, and it should be weighed against how many trips you realistically expect to take.

The raft is also not a complete kit on its own. A paddle, a personal flotation device, and several other accessories are required before the boat is usable, and those items are not inexpensive. Budget for the full setup rather than the hull alone, and expect the total to be meaningfully higher than the price of the raft.

Finally, this is a skill acquisition as much as a gear purchase. Reading current, choosing lines, and managing a loaded boat on moving water take practice, and the learning curve is real. Riders and hikers with no paddling background should plan for calm, forgiving water first and build experience before committing to anything ambitious.

Buying Advice

Buy the Caribou if you have specific trips in mind where water is the missing link. The strongest case is a bikepacking route that ends at a river, or a remote traverse where a float section replaces days of bushwhacking. In those scenarios the boat earns its place in the pack immediately.

If your trips are mostly on established trails and loops that close on foot, the value is harder to justify, and that is fine. This is a tool for a particular kind of adventure, not an upgrade to ordinary backpacking. Choose it because it unlocks terrain you could not otherwise reach, and the cost and the learning curve will make sense.

Start with an easy overnight on calm water to get comfortable with inflation, loading, and paddling a weighted boat. Confidence built on a gentle river translates directly to the bigger objectives.

Conclusion

The Alpaca Caribou is one of the more unusual pieces of backpacking equipment available, and unusual is the point. It weighs around 5 lb, packs into a bundle you can carry, keeps your gear dry inside the hull, and offers a front mount for a bike.

None of that makes it a universal recommendation. It is expensive, it needs additional accessories, and it asks you to learn a new skill. What it offers in return is a genuinely wider range of places you can go, and for backpackers and bikepackers who have been circling the same terrain for years, that trade is worth serious consideration.
