  The distance determination of small Bok globules is often difficult because
of its small size and opaqueness. In this work, we determine the distances to
six small Bok globules CB 17, CB 24, CB 188, CB 224, CB 230 and CB 240 using
near infra red photometry (2MASS $JHK_S$ colors). The distances to these clouds
are estimated to be $478 \pm 88$, $293 \pm 54$, $262 \pm 49$, $378 \pm 70$,
$293 \pm 54$ and $429 \pm 79$ parsec respectively.
