I was in the San Jose area for work, so I called up a buddy of mine (coincidentally also names John), and he was happy to hike Mt. Umunhum with me. So on a Sunday morning, we start the trek over to the trailhead, and the road is closed about 10 minutes from the trailhead. We stop, see a whole bunch of motorcyclists go through anyway, but we're not exactly confident in our car being able to continue. There was one other way up, so we turn back, go around the mountain to the other entrance, and as we're heading up, we see another sign that says “road closed.” We continue on, and when we get to the road closure, it turns out that it's not blocking off the road to the trailhead, but the other side of the same road that was blocked at the other entrance. Nice! So we continue up and finally make it to the trailhead.

The weather is awesome! Haha, no, just kidding. It's foggy as all hell. You can see about 20 feet in front of you, but no views. Anyways, we finally made it to the trailhead, we're doing this hike. So we start, and it's misty, kinda cold, but honestly, I'm just happy to be outside. The trail has tons of switchbacks and lots of trees (very hiking through the forest feel). Within the trees, the fog is substantially less, but outside the trees, it's just a wall of gray. Some parts of the trail are very muddy, but other than that, it's totally fine. There are even a few nice little waterfalls that have been created due to all of the rain we have been having.

We make it to the summit, and, continuing with the theme, there's no view. It's just a wall of gray fog. As we're walking on the summit, I see a silhouette of a big square building in front of us. The fog was so thick up top, the building literally came out of nowhere. So, after walking around the top a little, reading some info, looking at the big square building that is randomly on top of this mountain (turns out it was an old military radar station from the cold war era, but there wasn't any signage to tell you that's what it was), we take a few summit pics with the lack of background to prove we made it, and begin the trek back down. Of course, about 30 minutes into our decent, the fog clears up and the views are awesome! If only it had cleared up about 45 minutes earlier, that would have been better, but I'm glad that it wasn't just a foggy hike the whole time. We got some awesome views on the decent, and even had a moment or two on which turn/path we needed to make (since we were used to the fog, everything looked completely different without it).

Anyways, it's a pretty chill hike. Very easy and relaxing, nothing too challenging, awesome views, great for a Sunday hike. Check it out!
