Lake Fairfax is a huge park, notable for its park benches and water park.
But it actually has some lovely walking trails, as I discovered on this, my first hiking excursion to the park. You have to walk past the park benches, and into the woods beyond. A paved path encircles most of the lake (I wasn't able to walk around enough to find out if it goes around the entire lake).
The park is very popular, so you're unlikely to be alone. On the other hand, this means that there are plenty of people to talk to. I ended up chatting with a woman who owned a beautiful part-shepherd mix, and a couple of young boys who were collecting tadpoles.
The paths are well-tread, though rarely do they wander through truly beautiful country.
On the other hand, there are plenty of bathrooms and other facilities at the park; it's more like an amusement park in that way.
