Must be about time to put all these together in 1 thread. I thought there was one already, but can't see it right now.

Pha Bur R1334

The Pha Bur road is a hidden gem of a steep twister of a road. It is difficult to get photos in there & we had a crack at it this arvo.
Some vdo & a bit of drone fotage should be coming. But I do realise I need to go back again & spend a day out there.....any takers

I did this road last Thursday/Friday R1334-R1378. The switchbacks are something else on R1334, the steepest I've ever seen. I had to do them both ways the first time as I'd planned to take R1378 to Doi Mae Salong but it was around 5pm when I hit it, and as the MotoRex photos show,. its a bit loose and I didn't think it was a good idea with darkness approaching. So I got a night by Doi Tung and did it the next day, quite an epic journey! And had another run through the switchbacks.

Like everyone said 'it's hard to photograph.

Rode the Big Dipper a few days later, it really pales in comparison to the 1334 I think! Also took a quick detour on the 4029 on my way up to Chiang Khong (The sign said "Viewpoint 15km!" I couldn't resist) that I think was steeper than the Big Dipper and more enjoyable.

Here's to the steepies!

Oops I made a mistake the Pha Bur Road is R1334. Working to late. 55
The image & route # has been changed.
It links up with R1378 that runs down to R1130.

Lampang
I came over the Sirikit dam in the dark once and had the GPS set to shortest distance back to Lampang. My GF was pillion. And we ended up on the 4010 of course and in pitch darkness.
The lightbulb on the Crf headlights was shot - but luckily I had a set of foglights installed. It still was a quite nervewrecking experience to ride the 4010 in darkness with just a set of foglights working and a pillion on the rear of my Crf….

I will not forget that night easily….

I will have to lift my game.

Was this the Nong Tao road you did?

I think maybe Ian Yonok has done it too, but I can't find a trip report for it.

Yes David the road start from Nong Tao
and can see very well coming from 1155 and arrive between Phuchifa and Doi Pha Tang.
Also for me was first time I do it.
If I will use gps if my girlfriend let me know where my maps of gt rider are
and if my computer write not thai language
may be will be more easy to explain.:)
I will try to organize better for the future.

Doi Hua Mae Kham
In the past 15 years ago i sleep in national park more hight than last town
also recently I try to go there
but I cannot found anymore the way off road.

Nice post compliment

R2331 the Phu Hin Rongkla / Phu Ta Boek road.

GPS-Map054.JPG


IMG_4803.jpg


Why Phu Hin Rong Kla is so special....

PHU HIN RONGKLA
From 1968 to 1972, Phu Hin Rong Kla was a major stronghold of the communists in their battle with the Thai government.
In 1970 there were 31 wooden houses built in the camp HQs. After the 6th October 1976 uprising, many students and intellectuals fled the right-wing government purges in the Bangkok to hide in Phu Hin Rongkla. The PHR camp was used to educate the new recruits in communist ideology.
In 1982 combined governments force from the army, air force, navy & KMT troops attacked the Phu Hin Rongkla communist stronghold. They were not victorious, & supposedly defeated because of the rugged terrain & dense forest. In the battle massive damage was caused to the environment & wildlife (as you’d expect in a war).
According to
http://www.dnp.go.th/parkreserve/asp/st ... id=86&lg=2
Much of the forest was damaged and much of the wildlife was killed or fled to safer areas. Remaining wildlife includes tigers, leopards, Asiatic Black Bears, wild boar, fox, monkeys, leopard cats, wild hare and many bird species.
I’m not sure about the big cats still though! But it must have been good up there in those earlier years.

After the defeat in 82, with a fresh “hearts & minds” policy, plus amnesty, the area was won over by the government; & a road was soon built up onto the mountain and in 1984 it was declared a national park.

From
http://www.dnp.go.th/parkreserve/asp/st ... action.asp
Highlights of Phu Hin Rongkla include
• Lan Hin Pum, field of nodulated stone, whose lumps are roughly equal in size. It is believed that this formation resulted from physical and chemical erosion. Patients from the hospital suffering from fever would use the area as a rest spot, as a cool breeze blows over the area almost continuously.
• Pha Chu Thong where CPT cadres would hoist a red flag every time their forces defeated government troops in a battle or skirmish.
• Lan Hin Taek, (Broken Rock Field). Along the path, growing in rock crevices are various plant species, including mosses, ferns and ground orchids. The crevices, arranged in rough rows, seem to have come from the earth splitting. Peering into their depths can be eerie. Some crevices are narrow enough to jump across; others are wider. From several can be heard loud echoing of running water. The crevices were perhaps important to the communists, as they could have been used for hiding.
• Surviving wooden building structures
o Office for administrative staff,
o A printing press
o Communications centre.
• Bunkers & air raid shelter

Huay Lom / Huay Chanin to fame was the boob tax that started a rebellion against the government in 1962.

Despite being extremely poor, the Lua from the period around 1957 (2500 BE) were the most heavily taxed by Thai officials, often arbitrarily. These taxes included:
a stump tax, collected following the clearing of forest plots for agricultural cultivation;
an electricity pole tax, collected for the purpose of bringing electricity to the lowland areas;
a flashlight tax and flashlight battery tax, collected from any household caught purchasing a flashlight battery or using a flashlight;
a cold season tax, collected after villagers had collected wood for fires and making other preparations for the cold season;
an alcohol tax, collected after alcohol had been fermented;
a breast tax or flabby breast tax, collected from breastfeeding mothers. Those with longer breasts were taxed more than those with shorter breasts. It was a tax that caused tremendous resentment among the villagers. They would say, “Shorter breasts (small breasts) are taxed low while longer breasts (larger breasts) are taxed high. They would insult our women this much!” (from the research of Dr. Cholthira Satyawadhna in the book The Lua of Nan…)
In reality, there were many more annoying little taxes as well. These taxes were not collected from the lowland Mueang peoples, but deliberately collected only from the poor, marginalized, and uneducated upland peoples.

The Rebel Phi Boon of Huay Chanin Village
Other than the illegal tax collection described, there was still the problem of the killing of villagers’ pigs and chickens and the regular harassment of women. The villagers had to endure this miserable state for a while. Eventually, a village called Huay Chanin (after relocation several times - presently called Huay Lom Village, Amphoe Bo Kluea) tried to find a solution to their problem by consulting a holy man from Laos around the year 1962 (2505 BE). The holy man spoke of an ideal society, of divine intervention that would liberate all the Lua people from their current state of oppression. The leader of this fight was Ao Jong Wong (Po Yai Wong) from Huay Chanin Village. They tried to spread word of the uprising among different villages in the upland areas along the Lao border. Although the movement was based on superstition, it’s momentum would grow from a collective hatred for the illegal tax system, the mistreatment of women, and the forced labor imposed on the people. The holy man uprising spread widely in the uplands, bringing many from afar to join the movement. When news of the uprising reached the ears of the Thai officials, they sent armed forces to arrest Ao Jong Wong and his followers in 1965. Called the Phi Boon Rebellion by Thai officials, the uprising was crushed. Ao Jong Wong, himself, would eventually die in prison.

The Beginnings of the Stronghold
When the first armed military unit of the CPT reached Huay Chanin Village in 1968 (2511 BE), the first sight they witnessed was a village of only women and children with few to no men. The CPT learned that some men had been taken away in waves, some had died, and others imprisoned. After that, there was the case of a villager named Bo Rit. He had been taken away to be tortured by poison by Thai officials. Bo Rit didn’t die, but rather escaped and returned to Huay Chanin Village. As a result, the entire village was so fearful of the wrath of the state that they fled to the forest and sought refuge with the CPT comrades. This is how Huay Chanin Village became part of the stronghold in southern Nan, from which the movement would spread to surrounding areas.

Rak Thai is a Chinese KMT village situated on the Thai- Myanmar border, 45 kms north of Mae Hong Son city.

1683915420547.jpeg


Once upon a time it was a mix of Hmong, Lahu & KMT peoples.
Nationalist KMT soldiers, who had retreated from China after losing their war against the communists, came to settle at Rak Thai in 1967.
The village was originally known as Mae Aw, but was renamed Rak Thai in 1983.

May we add R6040 a 16km in and out road past "The Coffee Village" west of Mae Chai, to Chareon Rat School. The hill/road is the nemesis of 1st gear Wolgang formerly known simply as Wolfgang. 1st gear is too much, 2nd gear is not enough. The Phayao geriatric scooter group doesn't want to go up there again.:grinning:

Sorry, I don't know how to do all the fancy graphics.

R1130 - R1234 the Doi Mae Salong Road

Doi Mae Salong is a renowned Chinese KMT settlement near the Myanmar border, N-W of Chiang Rai city.

There are a couple of roads there
1. The main road from Mae Chan R1130 / R1234.
2. The "back way" from Kiu Sataa / Tha Ton R1089.
Both these roads are stunners for great biking.

I was curious which was steeper, the west 12 km of the 4009, or the steepest 12 km of the 3054. I used Excel to compare my Garmin GPS tracks of those rides. It was not easy but I have too much time on my hands when I am not riding. It turns out that they both cover about 1% of their distance at over 30% grade—no significant difference at the extreme—but only about 23% of the 3054 steepest segment is covered at over 15% grade, compared to about 31% of the 4009 west segment, so the 4009 is significantly steeper and may well be the steepest 12 km of road in Thailand.

3054.jpg 4009.jpg
I made some other comparisons (percentage distance at over 15% grade, based on Garmin tracks):
Route 4009 West Segment, 12 km: 31%
Elephant Pass to Viewpoint, 24 km: 28%
Route 1345 to Viewpoint, 14 km: 25%
Eng Neo Microwave Road, 7 km: 25%
Route 3054 Steepest Segment, 12 km: 23%

Excellent info.
You can take a look at this one & add a few bits if you like.

I'd love to see how the big dipper 4018 fits in our data.
David, here you are, I added a histogram for the Big Dipper. The charts show (1) the percentage of the route done by me at under 30 km, (2) the percentage of the route over 15% grade, and (3) the percentage of the route over 20% grade, calculated both by (a) distance and (b) time. I think the time-weighted comparisons are more meaningful than distance-weighted, because lower speed indicates higher difficulty for the rider on those sections, all else being equal, for two roads of equal steepness. We are grinding away in first and second gear, for up to half our moving time in some cases, for our safety, not for sight-seeing. Time-weighting indirectly takes the road curvature, narrowness, and roughness into account. Anyway, here are the comparisons both ways:

Steep Roads Summary.jpg


When sorted by the proportion of the route that is over 15% grade, calculated by moving time, the steepest three roads on this list are:
1. 4018 Big Dipper 4009 (11 km)
2. 4009 west segment (12 km)
3. 1345 viewpoint (14 km)

When sorted by the proportion of the route that is over 20% grade, calculated by moving time, the steepest three roads on this list are:
1. 4009 west segment (12 km)
2. 4018 Big Dipper (11 km)
3. 3054 steepest segment (12 km) and 1345 viewpoint (14 km) [tied for third place]

When sorted by the proportion of the route that is over 15% grade, calculated by distance, the steepest three roads on this list are:
1. 4009 west segment (12 km)
2. 4018 Big Dipper (11 km)
3. Elephant Pass viewpoint (24 km)

When sorted by the proportion of the route that is over 20% grade, calculated by distance, the steepest three roads on this list are:
1. 4009 west segment (12 km)
2. 4018 Big Dipper (11 km)
3. Elephant Pass viewpoint (24 km), 1345 viewpoint (14 km), 3054 steepest segment (12 km), and the 1090 near Umphang (80 km) [tied for third place]

As the senior biker, how would you define the “steepest” “road” in Thailand? What roads would be in your top 5 or 10? I’m happy to add a few more if you give me the start and end coordinates.

That's impressive. I'm glad we have you on board with GTR & loads of time on your hands.
I will give you a few more to compare, but I will copy this to the thread the Steepest Roads Thread.
Many thanks you're a star.
