Confirmed from Eastlake #3 Park & Nature Preserve's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

🏞️ beautiful scenery 8 mentions

“This is a beautiful Park and preserve, especially in the spring and summer time!”

Pretty lake! They are doing construction so we couldn't walk the whole trail.

★★★★☆ — Lisa , Apr 2021

This is a beautiful Park and preserve, especially in the spring and summer time! If you like to take walks, rollerblade, skateboard, or ride bikes oh, this is the place for you. It has wide and clear paths for doing all the things you love. It's not full of cracks, rocks, or any hazards that might make you fall.

★★★★★ — E , Feb 2019

It's a great place to walk your dog, run or ride your bike. Very scenic and pretty. A lot of people get photos taken here. It would be great if people picked up after their pets and paid attention when walking there dog instead of staring at their phones.

★★★★☆ — Robin , Oct 2019

East Lake trail is nice and easy trail to hike. Beautiful surroundings to look at. Very safe and always with people. Weather was perfect for a hike today. Would love to come back and hike with snow around on the ground. That would look so nice.

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.
