The waterfall at kilometre 11 or Tad Lak Sip-et is nothing to write home about but it's a pleasant enough spot to come and have a picnic with the locals.
They flock there to grill fish and have a swim, especially on the weekends and holidays.
The waterfall isn't that powerful, making swimming here safe and fun. Women should wear a sarong over their bathers or go in clothed. You'll need your own wheels or hire a tuk-tuk to get here. As the name suggests, it's 11 kilometres from Udomxai, on the road to Luang Prabang.
