About Op Khan National Park
Op Khan is the pick if you want nature without the crowds. It centers on a scenic limestone gorge with a river running through it and a handful of short nature trails, and because it's less known than the bigger parks, you can actually have parts of it to yourself.
There's no public transport out here, so you'll need a car or scooter for the drive from the Old City. It's not a long trip, but it's far enough that it keeps the casual tourist traffic away, which is really the point.
The gorge and stream look their best after rain, so green or cool season is the better window if you want the water at its most scenic.
Highlights
- Scenic limestone gorge with a river running through it
- Short, easy-to-moderate nature trails
- Far quieter than Chiang Mai's better-known parks
- Good half-day escape without the crowds
Tips
- No public transport, you'll need a car or scooter for the drive out
- Standard national park fee applies
- Visit after rain in green or cool season for the gorge and stream at their best
- Budget a half day rather than trying to rush it
How to get there
