Reddit mentions of Panther Martin UV6 Ultra Violet Assortment

I would go for a 2 piece or 4 piece light or ultralight action spinning rod. Amazon is full of suggestions with lots of reviews but for a low cost, relatively lightweight and tough rod an ugly stick is hard to beat. Here is a 6' light action rod which would be a great choice imo. https://www.amazon.com/Ugly-Stik-GX2-Spinning-Rod/dp/B00F0KM43G/ref=sr_1_19_sspa?keywords=shimano%2Bpack%2Brod&qid=1565000672&s=gateway&sr=8-19-spons&th=1 It is a bit more to pack than a 4 piece rod but strapped to the side of your pack should not be too obtrusive. As far as a reel again staying with the bang for the buck for the price I have had great luck with Pflueger President reels like this one. https://www.amazon.com/Pflueger-PRESSP30X-President-Spinning-Fishing/dp/B074WHM4PV/ref=sr_1_1_sspa?crid=2PMKS1QL76NWO&keywords=pflueger%2Bpresident%2Bspinning%2Breel&qid=1565001151&s=gateway&sprefix=pflueder%2Caps%2C153&sr=8-1-spons&th=1 I would spool it up with 4lb test.

Be sure to check the regs of where you are going bait may not be allowed but even if it is I would stick with lures. I would not want to fool with backpacking live bait, nothing stinks as bad as dead worms. LOL

Panther Martin, Roostertail and Joe's flies spinners are my go-to baits for trout. Small minnow baits like rapalas can be super effective as well. I am not going to list links for all but these but panther martin spinners are pretty deadly lures in my experience. https://www.amazon.com/Panther-Martin-UV6-Violet-Assortment/dp/B00AU5WNQO/ref=sr_1_4?crid=3A07BIDNZTDYW&keywords=panther+martin+trout+spinners&qid=1565001635&s=gateway&sprefix=panther+%2Caps%2C150&sr=8-4

Last but not least. Someone else suggested a Tenkara outfit and I have to agree with him. It is a very simple and lightweight system that lends itself well to backpacking. The learning curve is not as steep as you may think and really the only downside is casting range but on remote streams and lakes a lot of the time you don't need to cast as far. Here are a couple of blog posts I wrote about what I use backpacking. I am a fly fisherman but maybe it will give you some ideas.
