There are multiple routes to Johnson Lake via Pecos or the Santa Fe side of the divide. See Pecos Wilderness map from USFS. My preferred route is via Cave Creek on the Pecos side of the divide. This is an approximate 15 mile round trip hike. Johnson sits above 11,000 feet on the backside of Redondo Peak. On this trip we hiked and fished in mid June. Snow banks were still present around the higher slopes surrounding the lake. The lake contains cutthroats…Snake River and Rio Grande Cutthroats….some fish caught looked to contain a mix of both. The inlet and outlet of the lake contained many spawners, however we left them alone to do their deed, and we fished for the trout actively feeding within the lake. This is a good weekend trip if you’re seeking solitude, alpine trout, and beautiful mountainous country. Remember camping is prohibited in the bowl of the lake.
