Larry and I attempted to find Little Brown Lake, but it eluded us....however the next day Bella and I found Big Brown Lake. This was a pleasant hike about 45 mins up to the lake (and about the same back down) through some lovely Aspen groves and fields of the national forest.
I parked just off Silverlakes Rd and started down Road 706. Almost immediately we had to ford a small stream...well, Bella happily splashed her way to the other side. It was quite a relaxing and easy hike, with only one spot where I had to pick between a "steep" or a "steeper" path up the hill. The lake itself was quite expansive (where are the elk hiding?) and looking at a map, FDR 259 Rd comes close to the southern end of it. After pausing for a few pictures, Bella and I headed back down this scenic little trail.
All in all a delightful hike, and given the water, a good one if accompanied by your dog....and no GPS required.
