My UT roommate and I decided to take a road trip/fly fishing trip the summer I finished at UT and was headed off to grad school (roommate dropped out of UT a few years earlier). We loaded up his 4 Runner and drove up the eastern side of the Rockies to the CA border and then headed south to San Diego along the Pacific coast for about 5 weeks before heading back to Texas.
i had been fly fishing on the San Juan river the previous summer as part of my geology field camp class in the 4 corners area so we headed there first. Caught a bunch of trout there but decided if it was that good there, it would be even better as we headed north.
We stopped a few places along the way but didn’t catch crap...
Got to Yellowstone and after a few days of fishing but not really having any luck, we decided that we’d have one last fishing day before heading to the West Coast. We stopped by the fly shop we had been dumping money on the past few days and mentioned we were done and were leaving because the fishing wasn’t panning out as we had hoped. The guy in the shop said that before we left, he’d put us on a spot. He said to drive west past Quake lake west of W.Yellowstone, cross the first bridge we encountered west of the dam, park the truck there and walk west until we hit the first fence line and fish the hole there...
i caught at least 40 rainbows within 2 hours and it seemed to get a hit on every cast. My buddy was doing the same but fell in at one point and filled his waders with ice water so we had to cut the session short as he was freezing. Best fishing I ever had in my life... That being said - the dumbasses we were - we ended up packing up camp and headed to the west coast the next morning rather than going back to the same spot for the next few days as we were meeting some girls we knew in San Fran and later in San Diego... Yes, each of us ended up getting laid in Cali but I still kick myself 25 years later for not having spent another few days going back to that honey hole... Best fishing spot I ever visited...
Not sure if you can even access that spot any more but I plan on trying to get to the same spot next summer with my boys...
