Camping with diabetes is entirely doable for the vast majority of adults and children with the condition — the obstacles are practical (temperature, calories, equipment redundancy, emergency response) rather than medical. This guide covers insulin storage in both summer heat and winter cold, hiking calorie and carb planning, pump failure backup, bear-aware food storage, group communication, and the medical ID and satellite communicator habits that make backcountry trips safer.
Insulin Storage in the Field
Insulin’s two enemies are heat above 86 degrees Fahrenheit (30 C) and freezing. The 86-degree ceiling applies to in-use pens and vials over the 28-day open period; unopened refrigerated insulin needs the 36 to 46 degree range until first use. Practical field options:
- FRIO evaporative cooling wallet — soak in water, the gel beads release evaporative cooling, maintains 64 to 78 F for about 45 hours per activation, infinitely reusable; ideal for backpacking
- 12-volt thermoelectric cooler — car camping use; holds true refrigerator range with vehicle power
- Ice cooler — works but requires careful insulation; place vials in a plastic bag inside a sock to prevent direct ice contact and freezing
- Body-pocket carry in winter — to prevent freezing; sleeping bag at night, inner jacket pocket during the day
- Discard if frozen — frozen insulin loses potency and is not salvageable
Daily Calorie and Carb Math for Hiking
| Activity | Cal/hr (typical adult) | Carb plan |
|---|---|---|
| Flat trail, light pack | 200-300 | 15 g/hr if on insulin |
| Moderate elevation, day pack | 300-450 | 30 g/hr |
| Heavy pack (25-40 lb), uphill | 450-600 | 45 g/hr + basal reduction |
| Mountaineering / scrambling | 500-800 | 60 g/hr + meal stops |
| Camp chores (light) | 150-200 | Usually no extra |
For insulin users, a 20 to 50% basal reduction is typical on heavy-activity days, planned the morning of and continued for 12 to 24 hours after to cover the delayed glycogen-replenishment hypoglycemia window.
The Field First-Aid Kit
- 2x the insulin needed for the trip duration (one set in main pack, one set in dry bag with second person)
- Glucose meter plus 2x test strips and lancets, or CGM with backup sensor
- Glucagon — Baqsimi nasal preferred for temperature stability and ease of use
- Glucose tabs (at least 60 grams in main pack, 16 grams in pocket)
- Two pen needles or syringes per day, plus spares
- Alcohol wipes (small pack)
- Ketone strips (urine) or a ketone meter — DKA can develop in 4 to 8 hours with pump failure
- Medical ID bracelet or tag worn at all times
- Trip-specific medication list laminated and stored with the kit
- Satellite communicator (Garmin inReach, ZOLEO) for true emergencies if cell coverage is absent
Pump and CGM in the Wilderness
- Carry a backup long-acting insulin pen (Tresiba, Lantus, Toujeo) and rapid-acting pen as the pump-failure plan
- Bring 2x the infusion sets and reservoirs you expect to need
- Protect the pump from extreme temperatures — body-pocket carry in winter, FRIO sleeve in summer
- Waterproof the pump or detach it for swimming (most pumps tolerate sweat but not submersion)
- Carry spare CGM sensors and a backup transmitter battery (or backup transmitter if the system uses a separate transmitter)
- Have the manufacturer’s emergency hotline number written in a paper field card
- Know the manual injection backup math — total daily basal usually equals 50% of total daily insulin dose
Food Storage and Bear Safety
All food storage rules apply equally to diabetes supplies that contain sugar or strong-smelling items:
- Glucose tabs, gels, juice boxes, candy — store in the bear canister or ursack with food
- Insulin and meter — sleeping with you is generally fine (low scent profile) and protects from freezing
- Keep an emergency 16-gram glucose dose at the sleeping bag head for nighttime lows — the bear-safety trade-off favors having the carb accessible during a low
- Cook and eat at least 100 yards from the sleeping area in bear country
- Wash hands after handling glucose gel — the scent attracts wildlife
Group Communication
Camping with companions multiplies safety. Tell at least one person in the group:
- What diabetes is, and that low blood sugar is the emergency to recognize
- Symptoms — shakiness, confusion, sweating, irritability, slurred speech
- Where the glucose tabs are stored
- Where the glucagon is and how to use it (the Baqsimi nasal device is straightforward — peel, insert, push)
- When to activate emergency response — unresponsive, seizure, confusion not responding to glucose in 15 minutes
- The route plan and check-in schedule
Tent vs RV Considerations
- Tent camping — best for true wilderness; insulin temperature requires the FRIO/body-pocket plan; nighttime hypo response requires placing supplies within reach
- RV camping — refrigerator available; air conditioning protects insulin in summer; portable freezer/fridge units run on shore or battery power; supplies can be stored in normal locations
- Cabin camping — generally has electricity; treat like home for storage
- Hammock camping — fast-access glucose at the head of the hammock; FRIO wallet sleeve hanging from a guy line works for daytime insulin
Pediatric Type 1 Camping
Diabetes camps run by the ADA, JDRF-affiliated organizations, and standalone nonprofits (Camp Sweeney in Texas, Camp Nejeda in New Jersey, DECA in California, and many others) provide structured camping experiences with on-site medical staff including pediatric endocrinologists, certified diabetes care and education specialists, and trained counselors. Families considering general (non-diabetes) camping with a child with type 1 should bring written care plans, double supplies, and arrange a check-in with the camp medical director in advance.
DKA Risk and the Pump Failure Scenario
Diabetic ketoacidosis can develop in 4 to 8 hours from pump failure because insulin pumps deliver only rapid-acting insulin with no long-acting depot. Warning signs in the field:
- Glucose persistently above 250 mg/dL despite correction boluses
- Nausea, vomiting, abdominal pain
- Fruity breath odor (acetone)
- Rapid breathing or air hunger
- Confusion, lethargy
- Positive urine or blood ketones
The field response is to switch to pen injection immediately, give a correction bolus, hydrate with water, monitor every 1 to 2 hours, and evacuate to medical care if ketones do not clear within 4 hours or symptoms worsen.

The Bottom Line
Camping with diabetes is safe and rewarding with realistic planning. Three priorities cover most of the risk: keep insulin in its safe temperature range with a FRIO wallet or body-pocket carry, plan carbohydrate intake for the activity load with at least 30 grams per hour of moderate hiking, and carry redundant supplies including a pump backup plan with long-acting and rapid-acting pens. Tell your companions where the glucagon is, wear a medical ID, and consider a satellite communicator for remote trips. Pediatric type 1 families should look into structured diabetes camps as a first overnight experience. With these elements in place, a backcountry trip is no more dangerous than the daily commute.
