serithai park

so, i'm discovering that bangkok has all these parks tucked back in sois that you need to be a little savvy to find (or have a friend who runs a lot).
sirithai park flanks a canal/khlong that you could walk along for around 2 hours, i've heard. in the park, it's wider so that it's more like a lake. it's got some nice gazebos, paved paths, and plenty of carpety-grass for picnicking (i strongly suggest an isaan picnic).
plus, like any good bangkok-ian park, it has tai chi in the mornings, draka courts, evening dance-aerobics. downside is if you want to play soccer - none allowed on the pristine grass.

located on Serithai Soi 43, (about 200m into the soi) across from the Bueng Kum District Office.
