How to Plan Thru-Hike Resupply: Mail Drops, Towns & What to Pack

Resupply logistics quietly make or break a lot of thru-hikes — not because the concept is complicated, but because getting it wrong means standing in a gas station at mile 400 eating stale gas-station food, or worse, waiting two extra days in a trail town for a box that hasn’t arrived. Here’s how to actually plan it.

📚 For the food math itself, see our How Much Food to Bring Backpacking guide first — this article covers the logistics of getting that food to you on trail.

Two Strategies, and Why Most Hikers Mix Both

Buy-as-you-go: Shop at grocery stores, gas stations, or outfitters in each trail town as you reach it.

• Cheaper, more variety, no advance planning
• Lets you adjust based on what you actually crave (huge for avoiding trail food fatigue)
• Only works where towns have real grocery options

Mail drops: Pre-pack and ship boxes ahead to post offices or hostels along the route.

• Necessary for remote stretches with no real store nearby
• Lets you include specialty food (dietary restrictions, homemade dehydrated meals) you can’t buy on trail
• Costs more, adds planning overhead, and locks you into a schedule

The real answer for most thru-hikers: buy as you go wherever towns support it, and reserve mail drops only for the handful of stops that genuinely need one. Mailing every single resupply is the classic first-timer mistake — it’s expensive, rigid, and often means eating food you packed weeks ago and are now sick of.

How to Decide Which Stops Need a Mail Drop

Before your hike, research each resupply point and ask:

1. Is there a real grocery store, or just a gas station? A full grocery store means skip the mail drop.
2. Is it remote enough that hitching to a bigger town isn’t realistic? Remote + poor local options = mail drop.
3. Do you need something you can’t buy there (specialty diet, homemade meals, a gear swap like microspikes for the Sierra)?
4. Is it a resort/lodge-only stop where the only food option is expensive restaurant food? A mail drop can save real money here.

Most long trails only genuinely require mail drops at a handful of stops — plan those specifically rather than defaulting to mailing everything.

Building a Resupply Box

A good box covers food, consumables, and any gear swap for that stretch:

• Food for the number of days to the next resupply — see our food planning guide for the calorie math
• Consumables you’ll be low on: sunscreen, foot care/blister supplies, water treatment tablets, batteries
• A fresh pair of socks — a small luxury that makes a real difference by day 4-5 of a stretch
• Cash for laundry, showers, or a motel night if the stop doesn’t have an ATM
• Any seasonal gear swap: trade in a heavier layer for a lighter one (or vice versa) as conditions change along the route

Packaging & Shipping

• Freezer bags to repackage bulk food into single-day portions before it ever goes in the box — saves you from sorting a jumbled box at the post office counter.
• A permanent marker to label each daily bag and write your ETA clearly on the box exterior.
• A digital luggage scale to weigh boxes before shipping — useful for hitting a target food weight and for keeping shipping costs predictable.
• USPS Priority Mail boxes are free at any post office — no need to buy shipping boxes separately for that service.
• Address format: Your Full Legal Name, c/o General Delivery, [Town, State ZIP] — write “Hold for Thru-Hiker, ETA [date]” clearly on the outside. Most post offices near popular trails hold packages 15-30 days, but confirm with that specific office.

The Bounce Box

A bounce box is a box you mail ahead to yourself repeatedly — pull out what you need, add anything you’re sending home, then re-mail it to your next major stop. It’s for things you don’t need at every resupply but don’t want to carry the whole trail either: a first-aid restock, a paper map set for an upcoming section, dental floss and toiletry refills, a phone charger cable you don’t want in your pack daily. Not every hiker uses one, but it’s a useful tool for infrequently-needed items.

Common Mistakes

• Shipping fuel canisters via USPS air — not allowed. Ground-ship via UPS/FedEx with proper hazmat labeling, or just buy a canister at an outfitter near the stop instead.
• Timing a box to arrive after you do. Mail well ahead of schedule — hiker pace is unpredictable, and post offices won’t hold a box forever.
• Forgetting weekend/holiday post office hours. Small-town post offices often have limited hours and are closed Sundays — check before you’re standing outside a locked door.
• Over-mailing the same food. Boxes packed weeks or months ahead often repeat the same meals — trail food fatigue is real, and buy-as-you-go towns are your best defense against it.
• Under-ordering variety in a single box. If a stop is remote enough to need a full mail drop, make sure that box has enough variety to actually want to eat it for several days straight.

Sample Resupply Box Checklist

• Daily food bags (repackaged, labeled by day)
• Extra snacks/calorie-dense backups
• Sunscreen refill
• Water treatment tablets or filter backup
• Fresh socks
• Cash
• Any seasonal gear swap
• Blister/foot care supplies

Bottom Line

• Default to buy-as-you-go, and reserve mail drops for genuinely remote or poorly-stocked stops.
• Repackage food into daily bags before shipping — future you at a post office counter will thank you.
• Never ship fuel canisters by air — buy locally instead.
• Mail early, and check post office hours for your target town before you rely on a tight arrival window.
