Blue Lake Trail is a 12.6 mile lightly trafficked out and back trail located near Stevenson, Washington that features a lake and is rated as moderate. The trail is primarily used for hiking and walking and is accessible from July until October.
I expected warmer weather for July. 49 degrees at 11 am with fog so thick, you could not see any of the lakes along the hike. Once the incredibly strong winds died down the mosquitoes swarmed in. I think everyone out there packed up and left at the same time. Other than that, everything was beautiful.
Not sure if this the same trail for Blue lake but I start at Crest Camp Trailhead (Latitude: 45.90928 Longitude: -121.80252) which is of FR 60 in the Indian Heaven Wilderness. The hike follows the PCT (trail # 2000) all the way up to Blue Lake. Though the trail is straight forward there is a slight turn off to the right just beyond the cutoff for the Indian Racetrack (trail # 171A). The trail that goes straight is the southern meeting of the abandoned Cascade Crest Trail. Continuing on the PCT you will come to series of switchback as you traverse up the slopes of Berry Mountain. This is the major climb of this hike though you do descend after the saddle between Berry Mountain and Gifford Peak to reach Blue Lake. This is good hike with great views of Mount Adams, Red Mountain, Mount Hood, and St Helens and at the end stunning blue lake with Gifford Peak as a back drop. My GPS had the total distance as 16.7 with elevation gain 2,290 ft with highest point reached 5,010 feet.
Mellow grade through lowland forest into blueberry littered subalpine then cut past the PCT to stumble upon this beautiful lake with waters clear as gin. Great for swimming and overnight camping. There are several trails that lead to the lake we happened to take this route in as an extended day hike. Blueberries were plentiful and the subalpine meadows gorgeous with multiple open flats for frolicking in the sun. The lake tends to be relatively secluded during the week but can pick up as goodly number of groups on the weekend, particularly the holiday weekends. Regardless, the waters and terrain are well worth it and the lake big enough to support many visitors while maintaining some degree of solitude. Continuing past the lake will bring you to several open subalpine flats with smaller shallow ponds and copious amounts of blueberries. Plenty todo throughout the Indian Heaven Wilderness.
