A marshy lake near Elk Lake in Deschutes National Forest.
Lake Name: Hosmer Lake
Lake Coordinates: 43.95900, -121.78521
Lake Elevation: 4966'
Access: Drive up & unmarked "trail"
Note: This lake isn't accessible along the whole edge the boat launch area is the main point of access with lots of people kayaking and paddle boarding. I found a little trail from the end of the campground, but the water part of the lake wasn't really accessible from the "shoreline" it's too marshy. Trail only goes a little ways before heading back towards the road. It doesn't circle the lake and isn't marked or named.
This lake had very marshy edges. Except for the boat launch, water isn’t very visible. The parking lot for the boat launch was full so I wandered through the camp group and found a campsite where I tried to see if there was a view. Then at the end of the campsite loop I found an unmarked trail that looked like it might follow along the the lakes edge.
So I found a place to pull of and park my car near by and set off down the trail. I just wanted to see if I could see the lake and find a place to take a picture. There were quite a few places along the trail with a view of Sisters. It ended up being very marshy and water wasn't very visible. There was one section where I was able to see some water, but the main access to open water seems to only be the boat launch. I turned around once it appeared the trail was heading away from the lake and hiked by to my car.
The trail was easily visible but somewhat narrow. The terrain was pretty flat and it made for a fun adventure. I'd love to come back and kayake this lake.
