Here's what I'm looking for.

A lake within an hour or so of Kirkland/Bellevue/Redmond, that feels mostly undeveloped and has a few trout in it for my 3 year old.

I'm thinking something a little more adventurous than Cottage Lake. He loves hiking through the woods and in the mountains. The only problem is he just turned 3 which means dad carries him a lot on long hikes.

Any good ideas for fairly low elevation trout lakes that are off gravel roads or include a short hike or that you can hike around? Anyone ever try Lake Langlois?
