How close to Silver Spring? Does it need to be walking distance from downtown? There are a few in Takoma Park I could tell you about, but they're about 10 minute drive from downtown SS. Wheaton Regional Park is close to SS and is HUGE!
There are a ton of trails - Sligo Creek, Long Branch, Rock Creek are all near Silver Spring.
If you could tell me more about what you're looking for, I can give more specific answers.
Thanks! These are exactly the kinds of places I was looking for. Not too far away at all. Thank you so much!!
ETA: Mariposita, which parks do you recommend in Takoma Park? Playground and trails are what I'm looking for, but if there's just a particularly nice park you like going to, I'd be open to that, too. I only have a two year old.
