I returned here after visiting about 30 years ago, and was very impressed with the trails. You can…read morespend many days here and still not see all the areas the park offers. We parked at the Oak Opening area and hiked down to Lake Defiance, taking the Lake Defiance Trail. We stopped at the Nature Center to see some displays and chat with the ranger, and then continued our hike. Seeing the moraines, the leftover hills and ridges from the retreating Wisconsin Glacier, 10's of thousands of years ago, was a geologic trip through time. This is a great local state park that does not have an entrance fee! (None of our state parks have entrance fees to the best of my knowledge!) This is a place I can't wait to get back to explore, right in the backyard of the Chicago 'burbs!

Bluff Spring Fen is probably one of the most unique natural areas in the Chicago region. Bluff…read moreSpring Fen is a spring whose water is a year-round 50 some degrees so the spring never freezes. It also supports unique plant and animal communities that need the alkaline-rich soil and water to survive. To get to the entrance you have to enter and park in the Bluff City Cemetery and drive to the rear section for parking and access to the preserve. The cemetery closes at different times during the year so pay attention to the signs! (For cemetery buffs, Bluff City is spectacular - rolling hills of mature oak among the headstones and memorials...) Bluff Spring Fen is located on gravel hills that were left behind when the Wisconsin Glacier retreated around 20,000 years ago. Gravel is a soil type, and I've climbed a large hill full of purple cone flowers and realized I was standing on a bed of gravel!! That's pretty cool in my nerdy book!! This preserve is also adjacent to a gravel mine and I'm told the preserve almost became a gravel mine until it was saved and turned into a preserve. There is also a group of FPCC volunteers who have been working here for many years. There are many single track hiking trails here. I don't believe bikes are allowed and this is a good thing - the trails are narrow and go through tall grasses and flowers - not an ideal biking area. Come and see Bluff Spring Fen in person and enjoy this very unique natural Cook County area.

It goes from Oswego all the way up to Algonquin, so that's a long way to go between the end points. Curve around buildings and rivers along it. There's enough room for bicycles, joggers, and whoever. Get on the trail from many areas. It goes a long way following the Fox River. This is a long ass trail. It makes it a way to get around without driving. Kind of hard to get to from where it starts and where it ends. It's too long for most people to walk along it. The part in East Dundee is especially scenic. It goes through the restaurant district. This goes by the old depot that's now used as a place for some people to hang or sleep. Has a long way to go for joggers and exercisers. It has enough room for bicycles and other faster transportation methods. There's plenty of parking spots along the way and you can find many places to eat as it goes through a few towns.

Has about 5 miles of trails and recently they have added on off leash area for dogs, with plenty of room to run and play.

If I were more of a mountain bike enthusiast, this would be an oasis. Even just walking and hiking around, the many twisting, undulating trails proved interesting and exciting (though I was constantly looking over my shoulder, waiting to get run down; people on bikes get entitled, y'know...). Knowing the history of the racecourse, it is astonishing - and maybe a testament to the work of the forest preserve - how little this place resembles what it once was. Aside from pavement, which you might as well just assume was a paved path, and the big fuel silo, this place once again belongs to nature.
