Some post-booking changes are simple; others are constrained by paperwork that's already been filed and can't be reversed. Date changes are usually possible if your departure hasn't reached its "guaranteed" booking threshold, adding days to an existing itinerary is routine, and upgrading from a group departure to a private one just means paying the private-tier rate difference. What doesn't move: a restricted-area permit for Manaslu, Upper Mustang, Dolpo, or Kanchenjunga, once filed with the Department of Immigration, is priced and issued for a fixed date block with no refund for early return, so a request to shorten a restricted-area trip after the permit is filed doesn't get that portion of the fee back regardless of the reason.
This is a narrower question than "how does customization work," covered on the Customized Nepal Travel Packages page for someone booking a new custom itinerary from scratch. This page is about changing something you've already booked and paid a deposit on. The sections below cover what's realistically changeable, what genuinely isn't, and how this interacts with the site's cancellation policy.

What can you actually change after booking a fixed package?
Three changes are realistic on most bookings: shifting your departure date to another scheduled date on the same route, adding extra days to your existing itinerary, and upgrading from a group departure to a private one. A date shift works most easily while your original departure is still marked "open" rather than "guaranteed," since an open departure hasn't locked in the group size that makes rebooking straightforward; once a departure crosses into "guaranteed" status, most of the group has already confirmed and permit paperwork may already be in motion, so a date change at that point depends on whether the new date has its own open seats to move into.
Adding days, extra acclimatization time, an extra night at a teahouse, or a side excursion, is routine on nearly any route and priced at roughly the same per-day rate the base itinerary already implies, the same logic covered in the customized package process page's worked examples. Upgrading to a private departure mid-process means paying the difference between the group rate you booked and the route's private rate, since a private departure doesn't share guide and transport costs across other travelers the way a group booking does.
Why can't a restricted-area permit be changed once it's filed?
Because the Department of Immigration issues restricted-area permits, for Manaslu, Upper Mustang, Dolpo, and Kanchenjunga, in fixed date blocks that are paid for and processed before your trek starts, and that process has no early-return refund mechanism. The Dolpo restricted-area permit guide states this plainly for Dolpo specifically: a permit priced at USD 500 for the first 10 days plus USD 50 per additional day carries no refund whether the itinerary runs shorter because of weather, altitude illness, or a simple change of plan. Manaslu's restricted-area permit works the same way, covered in the Manaslu permit guide: once filed, the fee is spent regardless of what the actual trek ends up looking like.
This matters specifically for post-booking changes because it means shortening a restricted-area trip after the permit has been filed doesn't return that portion of your payment, even if the operator is happy to accommodate the shorter itinerary logistically. A date change on a restricted-area route, by contrast, is more workable before the permit application goes in than after, so raising a date change early gives you meaningfully more flexibility than raising it once the paperwork is already filed.
How does this interact with the cancellation and deposit policy?
Any change that shortens your trip or reduces its cost close to departure runs into the same refund windows that apply to a full cancellation, covered in full on the cancellation and refund policy page: 45 or more days out returns a full refund minus the deposit, 30 to 44 days returns 50%, 15 to 29 days returns 25%, and under 15 days returns nothing. A deposit itself is non-refundable at any point after booking, since it covers permit filing and guide allocation that begins immediately, the same reason a restricted-area permit fee doesn't come back once filed. A change that adds days or upgrades to private, rather than shortening or cancelling, isn't a refund scenario at all; it's simply billed the difference.
The practical takeaway: a change requested well before departure, ideally more than 45 days out, has the most room to work with regardless of what kind of change it is. A change requested close to departure is constrained less by whether we're willing to accommodate it and more by what's already been paid for and filed on your behalf.
Who do you actually contact to request a change?
Message the guide listed on your trip's page directly, the same contact route every booking on this site already uses, rather than a general support inbox. State what you want changed, dates, added days, or a group-to-private upgrade, and your original booking details so the guide can check your departure's current status and any permit paperwork already in motion before quoting what the change costs. A request made this way gets a real answer faster than a general inquiry, since the guide who owns your route can check departure status and permit timing directly rather than routing the question elsewhere.
FAQ
Common questions
Can I change my departure date after booking?+
Often yes, especially if your original departure is still marked "open" rather than "guaranteed." Once a departure reaches guaranteed status, a date change depends on whether your preferred new date has open seats, since most of the group and any permit paperwork may already be confirmed.
Can I get a refund if I shorten a restricted-area trek after booking?+
Not for the permit portion. Restricted-area permits for Manaslu, Upper Mustang, Dolpo, and Kanchenjunga are priced in fixed date blocks by the Department of Immigration with no refund for early return, once filed. This applies regardless of why the trip runs shorter.
Does adding days to my trip cost extra?+
Yes, priced at roughly the same per-day rate your base itinerary already implies for guide, accommodation, and food. This isn't a refund or cancellation scenario, so the standard cancellation-policy refund windows don't apply to it.
Can I upgrade from a group departure to a private one after booking?+
Yes. You pay the difference between the group rate you booked and the route's published private rate, since a private departure doesn't split guide and transport costs across other travelers the way a group booking does.
Who do I contact to request a change to my booking?+
Message the guide listed on your trip's page directly, the same contact route used for the original booking, with your original booking details and what you want changed. They can check your departure's current status and any permit timing before quoting the change.
