Caribou Lakes Trail to Upper Caribou Lake

Hike through the most majestic and unforgettable mountain ranges, alpine terrains, glacier lakes outside of the Sierra Nevada in Northern California. Yes, it's a long drive there and a lengthy hike, but if you have any doubts about whether this is worth the effort, just go! I struggled with the same doubts about the trip, but could not be more thankful that I got to do this hike.

This is a traditionally a backpacking trip where hikers can spend the night at the Caribou Lake basins (e.g., "infinity pools"). However, for those short on time, this can be done in 7-9 hours as a day hike.

The trailhead starts at the Big Flat campground in the Shasta-Trinity Wilderness. Please note that the last portion of the drive to the trailhead is on unpaved road so higher vehicle clearance would be helpful (I drove a Honda Civic without any issues, although the last 10-15 miles on unpaved road took 45 minutes to drive).

Once at the parking lot, the trail (at ~5,000 feet elevation) will be marked with a sign to Caribou Lakes. From the start, the path descends down to a river, which must be crossed on foot. Once you cross the river, the trail splits into the "Old Caribou Trail" and the "New Caribou Trail." The New Trail is slightly longer than the Old (9 miles vs 7 miles), but has a much friendlier grade/incline and is the recommended route based on several guides online and my personal experience.

Following the New Caribou Lakes Trail, follow the switchbacks up the side of Caribou Mountains under the forest shades. Soon enough, the tree lines will begin to clear and views of various mountain peaks will become visible. Follow the New Trail through a meadow and than continue on as the path carves into the side of the granite mountain cliffs. Starting from here, the alpine terrain and views become quite incredible, with mountain ranges stretching far out into the distance.

The downside of any day hike is that you are often racing against clock and trying to make it back by sundown. I got to the trailhead at noon after a 5-hour drive and came back to my car at around 7pm. To save time, I recommend that you hold off on the "scenery/photography stops" before getting to the lakes. The scenes are beautiful along the entire route but the apex is really the lakes. Of course, personal preferences vary so make sure you do what works for you, keeping in mind that you need to optimize for time on a day hike. If you have a day to spare, I strongly recommend doing this as a backpacking trip.
