The Buffalo Valley Recreation Authority is the Parks department for Lewisburg.  They have a couple of facilities where they host programming including: Lewisburg Park, a Nature Studio, a beautiful pool and a gymnastics facility (see LINK).  Their facilities are really amazing and more impressive is their programming for the community.  Keep an eye on their website for programming, including Jujutsu, Brazilian soccer camp, archery, skateboarding camp, tennis lessons, chess club, nature programming, art classes and more!  You can make a full day out of playing at the playground with little ones (bring food for the geese!), and older kids love this playground as well with the huge spider web.  Leave a note in the comments if you have a favorite program, or something else that you think would help other parents out!

They offer really cool birthday parties!  Nerf, glow in the dark and ninjastics are a couple of examples:  http://bvrec.org/gymnastic-center-events/
