🥾 My Experience Hiking Annette Lake (Early April)
I hiked Annette Lake in early April, and the conditions were a mix of winter and spring.
Most of the trail was clear, but the last mile still had snow and ice. I didn’t bring microspikes and was able to complete the hike, but I would definitely recommend bringing them for safety, especially near the lake.
The hike is about 7.5 miles round trip, and it took me just under 5 hours at a relaxed pace.
It wasn’t very crowded when I went, which made the experience more enjoyable. I did see a few other hikers, so it didn’t feel isolated, but it was much quieter compared to peak season.
When I reached the lake, it was still completely frozen. I even walked on the ice, which felt a bit risky but also made the experience unique and memorable.
Parking was easy during this time, but that’s mainly because it’s not peak season. In summer, parking is limited, so I would definitely recommend arriving early.
Overall, the lake is beautiful, and the hike is worth it if you’re looking for a peaceful forest trail with a rewarding ending.
