We went to the Big Bear Discovery Center to find out how to hike there. They told us we couldn't go see it. There is an access road that gets you 0.6 miles away from the tree, but the access road was closed, and the only way to get there is to hike four miles in over moderate to difficult terrain.
The trail head was 0.6 miles from the Discovery Center (~6,900 feet), so we just hiked along the lake to the trail head. It was a great hike with great views of the lake. It had been a long time since I had hiked a trail like this so there were parts that winded me, but when we reached top, it was worth it. At the top you are hiking along the Pacific Crest Trail, which is a well-known trail that goes from Mexico to Canada. It felt good to think about all the brave people that have taken this trail.
We decided to go for it because we had some extra time. It turned out to be the steepest part of the hike. There were event better views of the lake along the way, which kept us inspired and also gave us something to look at while we rested. We seriously considered stopping because we were all getting so tired. We were promised a 360 degree view of Big Bear Lake and the Holcolm Valley on the other side of the mountain, so we pushed on.
At 1pm, over 1600 feet higher, we finally made it! The view on the other side was pretty but not spectacular. The Holcomb Valley is not developed like Big Bear is. The area is almost unspoiled. All three of us didn't remember to bring a camera, so no pictures of our actual trip, sorry.
