All guests are required to sign a waiver before joining the trip. By signing this document, guests will waive certain legal rights, including the right to sue. Please read this form carefully before signing. All guests are required to complete a guest registration form before joining the trip.

Cancellation Policy
Because we are a small company with a very limited floating season, we cannot assume the risk of loss for guest cancellations. Consequently, neither deposits or full trip fees are refundable.

All cancellations must be received in writing.

Guest Substitutions
Guest substitutes are welcome. However, no refund will be given to the original booking party.

Late Payments
Any payment not received within 30 days of invoice may act as notice of cancellation. If payment is not received on time, Boundary Expeditions reserves the right to cancel the booking and re-sell the space. There will be no refund for the original booking.

Boundary Expeditions Cancellation
Boundary Expeditions reserves the right to cancel trips, at our sole discretion, at any time in the interest of the safety of our guests and staff due to water or weather conditions, fire danger, obstructed access to/from the river, due to personal or public health-related issues, acts of God, or due to changes in permits, policies, regulations or laws of any government, or states of emergency.

Travel Insurance
We understand that occasionally events occur that prevent you from joining us on your scheduled trip. Please pay special attention to our Cancellation and Refund Policies. To avoid any financial hardship that an unexpected cancellation and interruption could cause, we strongly recommend purchasing Trip Cancelation/Interruption insurance to protect your trip investment.

There are no exceptions to our policies so we strongly suggest that all guests purchase trip cancellation insurance.

In limited circumstances Boundary Expeditions may allow trip deposits to be deferred to a later date. If allowed, deposits may be deferred to the following year. Any subsequent deferrals will be considered as a cancellation and deposit will be lost.
