Hiking poles for Yellowstone/ GTNP

I purchased my pole from Amazon. Forgot the name brand. It folds up so I can put it in my suitcase.

Mine are the "Black Diamond" brand which were purchased at REI, and I have been very pleased with them. They do collapse, and are packed in my check through luggage. On multiple occasions, I have seen TSA confiscate hiking poles that were in traveler's carry on bags.

Pretty much all hiking poles can collapse into a small enough size for carry-on luggage. Whether or not you’re actually allowed to take them on board is an entirely different matter. Make sure to check and double check the security measures of both the airline and the airports.
