Grand Canyon National Park recently updated their noncommercial river trip regulations. The new regulations are dated October 2, 2018. River trips are required by the Park to have a printed copy of the regulations with them at all times. Regulations dated earlier than this are not sufficient. The new regulations can be viewed and printed at this link:
River trips without the current regulations will have delays during the river trip orientation with the Lees Ferry ranger. The river trip permit holder has the responsibility of ensuring that all participants comply with the terms and conditions of the river trip permit as stated in the Noncommercial River Trip Regulations.
Included in the new regulations is language GCPBA discussed with the Park about various topics, noted in Appendix B on page 31.
