Mae Ya Waterfall is a broad, tiered cascade in the southern part of Doi Inthanon National Park, near Chom Thong. Water spreads over a stepped rock face surrounded by forest, creating a different spectacle from a narrow waterfall dropping into a single pool.
Its lower viewing area is reached by a short walk from the parking area. The waterfall lies on a separate access road from the main Doi Inthanon mountain route, so include it deliberately in your itinerary rather than expecting to pass it on the way to the summit.
The Cascade and Forest Setting
Mae Ya’s appeal is the width and layered form of the falling water. From the public viewing area, you can appreciate the repeated rock ledges and the contrast between pale water and the surrounding green forest.
Water volume changes through the year. Wetter periods can create a powerful, wide curtain, while drier conditions reveal more of the rock and individual channels. Both offer a worthwhile view, but recent rain also affects path conditions and access.
Avoid planning the visit around claims that it is Thailand’s biggest waterfall or the highest single drop in the park. The cascade comprises many levels; the part seen from the visitor area is one section of a much larger watercourse.
Visiting the Waterfall
The Walk from the Parking Area
The approach is a short forest walk of roughly 300 metres from the parking area. Allow time for the path as well as photographs, particularly after rain when surfaces can be wet or muddy.
Wear shoes with grip and keep to the established route. Tree roots, damp stone and uneven ground make this different from a level urban footpath. Visitors with limited mobility should check the current path and viewing-area conditions with park staff before travelling.
Stay within the permitted viewing space and respect barriers. The waterfall is best treated as a place to look at and photograph; do not assume swimming or climbing on the rock face is permitted. Strong flow and slippery rocks can change the conditions quickly.
Park Tickets and Visiting Hours
Mae Ya has its own national park checkpoint. Doi Inthanon admission is 300 baht for foreign adults and 150 baht for foreign children aged 3 to 14. Thai admission is 60 baht for adults and 30 baht for children, with vehicle charges of 30 baht for a car and 20 baht for a motorbike.
Keep your ticket if you are continuing to other Doi Inthanon park attractions the same day, and confirm its use with the checkpoint staff. Separately managed attractions, guided walks and optional services elsewhere in the area can have additional charges.
Plan a daytime visit, generally within an 8am to 5pm window, and follow the checkpoint’s current access arrangements. Heavy rain or other conditions can lead to temporary restrictions; an advertised general schedule does not override instructions from park staff.
Driving to Mae Ya Waterfall
From Chiang Mai, travel south towards Chom Thong on Highway 108. Turn onto Highway 1009, the Doi Inthanon road, then follow the signed Mae Ya turn-off near the beginning of that route. The waterfall access road branches away from the main climb towards the mountain.
The final approach is around 14 kilometres along the local access road, followed by parking and the short walk. Use Mae Ya Waterfall as the specific destination in navigation rather than the national park headquarters, which takes you towards a different part of the park.
A private driver, rental vehicle or tour that expressly includes Mae Ya is the most practical choice. Many Doi Inthanon itineraries focus on the summit, pagodas and waterfalls beside the main road, so check Mae Ya is named in the programme before booking.
If using a driver, agree waiting time and the rest of the route. Reaching Chom Thong by public transport does not provide an automatic connection to the waterfall entrance, and the detour adds meaningful time to a mountain day trip.
Facilities and Planning the Day
Parking and basic visitor facilities are available near the approach. Food and drink availability can vary, so bring drinking water and do not depend on a particular stall being open. Use designated areas for any snack break and take your rubbish away.
Allow around an hour to 90 minutes for the walk, viewing and a relaxed return to the car. Add the access-road detour to your total driving time, especially if you also intend to reach the upper mountain before attractions close.
The cooler months often provide more comfortable travelling conditions, while the rainy season can bring stronger flow and greener forest. Choose the visit according to weather and access, and allow flexibility if rain changes the day’s plans.
For an overnight Doi Inthanon trip, arrange accommodation or an authorised campground separately. Do not arrive at the waterfall with a tent on the assumption that camping beside the cascade is allowed.
Mae Ya Waterfall FAQs
Is Mae Ya Waterfall inside Doi Inthanon National Park?
Yes, in its southern section. It has a separate access road and checkpoint, so visiting it involves a detour from the main road towards the summit.
How much is entry?
National park admission is 300 baht for foreign adults and 150 baht for foreign children aged 3 to 14. Thai rates are 60 baht for adults and 30 baht for children; cars cost an additional 30 baht and motorbikes 20 baht.
How far is the walk?
The approach is roughly 300 metres from the parking area. It is a short walk, but surfaces can be uneven and slippery, so allow extra time in wet conditions and check access if you have mobility needs.
Can you swim or climb the falls?
Treat Mae Ya as a viewing and photography stop, and follow park signs and ranger instructions. Do not assume swimming or climbing is allowed; the stepped rock face and changing flow require care.
Do all Doi Inthanon tours visit Mae Ya?
No. It is away from the main mountain road, and many tours use other waterfalls. Check that Mae Ya is specifically included, along with enough time for its access-road detour and walk.
Can you use the same park ticket elsewhere?
Keep your ticket for further Doi Inthanon park stops that day and confirm it with checkpoint staff. Separately managed attractions and optional activities can still have their own charges.
How long should you allow?
Around one to 1.5 hours covers a relaxed walk and viewing visit. The drive along the separate access road is additional, so include that detour when planning a longer mountain itinerary.
