I have paddleboarded on this lake in the past, it's quite full of milfoil and so can be kind of a challenge to paddle. Plus the fishing restrictions because of the forever chemicals that have leached in from nearby businesses is sad. But it is nice to look out on while pedaling around it!

The gravel/grass trails at Lake Elmo Park are great for both solo and riding in a group I would guess, since they are plenty wide to ride 2 by 2.

Trailhead to the trail system. Easy loop was actually a little more challenging then I was expecting. Some drops, lots of roots, etc.

There is a bench here, overlooking a 100 foot drop to the river. I was here years ago when it was just a single walking path, it's neat in the fall.
