For long walks and hikes, the best snacks are easy to carry, easy to eat on the move and matched to how hard you are working. At an easy, chatty pace (lower heart-rate zones), mixed snacks with some protein and fat, like trail mix or a nut butter sandwich, keep you going. On steep climbs or faster sections (higher zones), quick carbohydrates such as bananas, dried fruit or fig bars are easier to digest and get into your muscles faster. Pair snacks with regular sips of water, and eat a little every hour rather than waiting until you are drained.
Heart-rate zones in plain language
You do not need a watch to use this. Most zone systems run from Zone 1 (very easy) to Zone 5 (all-out). For walks and hikes, three bands are enough:
| Band | How it feels | What your body burns most | Snack focus |
|---|---|---|---|
| Easy (Zones 1–2) | You can hold a full conversation | A mix of fat and carbohydrate | Mixed snacks: nuts, seeds, nut butter, whole grain, fruit |
| Moderate (Zone 3) | You can talk but not sing | More carbohydrate | Mixed snacks with more fruit and grains |
| Hard (Zones 4–5) | Only a few words between breaths, such as on steep climbs | Mostly carbohydrate | Quick carbs: banana, dried fruit, fig bars, chews |
The talk test lines up with Mayo Clinic’s description of intensity: at a moderate level you can talk to someone, but you can’t sing, and at a vigorous level you can’t say more than a few words without pausing for breath.
Most of a typical hike is easy to moderate, with harder bursts on hills. Pack mostly mixed snacks plus a few quick carbs for the climbs.
How much and how often
Parks Canada’s hiking advice is to bring nutritious, high energy snacks, and pack a more complete meal if you are going longer than a few hours. A practical rhythm:
- Under an hour, easy pace: a regular meal beforehand is usually enough; bring water and one snack in case.
- One to three hours: a small snack every 45–60 minutes.
- Longer than three hours: snacks every hour plus a proper lunch, such as a wrap or sandwich.
- Big climbs: eat a quick-carb snack just before or partway up, not only at the top.
Always pack more than you think you need, in case the hike takes longer or the weather turns.
Snacks for easy, chatty miles
- Trail mix: mix your own with almonds, peanuts, pumpkin seeds, raisins, dried apricots and a few chocolate chips or whole grain cereal.
- Nut butter sandwich or wrap: peanut or almond butter with banana or jam on whole grain bread.
- Cheese and crackers: hard cheeses travel better than soft ones.
- Roasted chickpeas or edamame: crunchy, salty and higher in protein.
- Nut butter squeeze packs: easy to eat with one hand, with a few pretzels.
- Homemade energy balls: oats, nut butter, ground flax, honey and dried fruit, rolled and chilled.
Snacks for climbs and faster sections
- Bananas (pack in a hard container or eat early)
- Dried fruit: dates, figs, mango, apricots, raisins
- Fig bars or soft granola bars
- Applesauce or fruit puree pouches
- Rice cakes with honey or jam
- Fruit chews or energy chews
These are lower in fat and fibre, so they digest quickly while you are working hard. Save the higher-fat options for flatter stretches and breaks.
Avoiding energy crashes
Candy and sweet drinks alone can give a quick lift followed by a dip. You do not need to avoid sugar on the trail, since it is useful fuel during hard effort, but pairing it helps:
- Eat dried fruit with a few nuts.
- Follow a quick-carb snack on a climb with a mixed snack at the next break.
- Eat before you feel empty. Feeling shaky, cranky or suddenly heavy-legged is a sign you have waited too long.
Water and electrolytes
Parks Canada suggests planning on drinking about half a litre of water per hour of hiking and not waiting until you are thirsty. Needs vary with heat, pace and body size. The American College of Sports Medicine notes that because sweat rates vary so much between people, customized fluid plans are recommended, and drinks containing electrolytes and carbohydrates can help over water alone in certain circumstances, such as long or hot efforts.
- Start the hike well hydrated with a glass or two of water at breakfast.
- Sip regularly rather than gulping a lot at once.
- On long or hot hikes, add salty snacks (pretzels, salted nuts, crackers) or an electrolyte drink.
- Do not overdrink plain water far beyond your thirst and sweat losses on very long outings.
Our guide to hydration timing covers what to drink before and after exercise.
Lunch and recovery
On longer hikes, a real lunch keeps energy steadier than snacking alone: a wrap with hummus, vegetables and cheese or chicken; a pasta or grain salad in a sealed container; or a bagel with peanut butter and an apple.
After the hike, have a meal or snack with protein and carbohydrate within a couple of hours, such as chocolate milk, yogurt with granola, or a sandwich with fruit. See our high-protein snack ideas for more.
Sample snack plans by outing
| Outing | Before | During | After |
|---|---|---|---|
| 90-minute brisk walk, flat | Regular breakfast | Water; an apple or small handful of trail mix | Next regular meal |
| 3-hour hike with one big climb | Oatmeal with fruit and nut butter | Trail mix at 1 hour, fig bar before the climb, banana at the top | Yogurt with granola or a sandwich |
| 6-hour day hike | Eggs, toast and fruit | Snack every hour, alternating mixed and quick-carb; wrap or bagel lunch; salty snack in the afternoon | Full meal with protein, carbs and vegetables |
Make-ahead trail mix
Combine one cup each of almonds and peanuts, half a cup of pumpkin seeds, one cup of raisins or chopped dried apricots and one cup of whole grain cereal squares. Add a handful of chocolate chips if you like. Portion into small bags of about a third to half a cup so you can grab one per hour.
Packing checklist
- Water (and a way to carry enough for the whole trip)
- Two or three mixed snacks
- Two quick-carb snacks for hills
- Something salty
- Lunch if out more than three hours
- An extra snack for emergencies
- A bag to pack out all wrappers
When to check with a professional
If you have diabetes, especially if you use insulin or medicines that can cause low blood sugar, talk with your healthcare team about adjusting food and medication for long hikes and carry fast-acting carbohydrate. See your doctor before strenuous hiking if you have heart or lung conditions. Stop and seek help if you feel dizzy, confused, have chest pain or stop sweating in the heat.
Takeaways
- Easy, chatty pace: mixed snacks with nuts, seeds and whole grains.
- Climbs and fast sections: quick carbs like bananas, dried fruit and fig bars.
- Eat something every 45–60 minutes on hikes longer than an hour, before you feel drained.
- Drink regularly; add salty snacks or electrolytes on long or hot days.
- Pack extra food and water, and refuel with protein and carbohydrate afterward.
