Kasi Hell Valley, located in Kasi Village on the west side of Mount Gongga, stretches from Kasi Village in the south to the Xigerang Ancient Cirque on the western slope of Xiannairi in the east. The 12-kilometer-long valley reaches a maximum depth of 1,000 meters. Its walls rise a thousand feet high, creating a breathtaking spectacle. Stunning and treacherous scenes, such as the Gate of Hell, the Hall of Yama, Ghost Cliff, Tathagata Peak, and the Black Waterfall, formed by grotesque cliffs and rocks, are vividly portrayed, inspiring the imagination. The weathered dolomite at the end of the valley, forming a divine mirror, a scale, a side knife, and a sword, all depicting "tortures of hell," perfectly embody the legend of "Hell Valley," creating a truly astonishing sight.
Kas Hell Valley, one of the eight great cold forests (corpse forests) mentioned in Buddhist texts, is the only way for the human body to pass from the mortal world to heaven. Crossing Hell Valley, one truly reaches heaven—the "Mount Sansara."

Kasi Hell Valley (Kasi Canyon) lies in Daocheng County, within Garzê (Ganzi) Tibetan Autonomous Prefecture. It is considered a somewhat remote “hidden canyon” natural attraction. The canyon is prized for its pristine landscapes, forested slopes, river corridors, and as part of the wider high-altitude scenic region around Yading. It’s less developed and more wild, which appeals to adventurers seeking less-crowded nature.
The canyon is west of Yading Park, and east of Kasi Village (the canyon is named after the village) To reach it:
The canyon is a natural area and generally accessible during daylight hours (approx. 8:00 AM to late afternoon). Best times: late spring through early autumn (roughly May to October) when trails are snow-free and river crossings safer. Summer brings wildflowers; early autumn offers crisp light and colors. Winter or early spring may have snow, frozen sections, or dangerous river crossings.
I did not find confirmed, official information about an entrance fee for Kasi Hell Valley. Given its nature as a less commercial canyon, it might have modest local access fees or be free. Payment, if any, would likely be at a local gate or via local operators (offline).
Because the site is remote and not heavily formalized, it is unlikely you need to pre-book tickets well in advance. However, during peak seasons, or if using guided hiking services, arranging logistics (transport, guided support) ahead is wise.
Many visitors report hiking times of 4–6 hours round trip (ascent + return) depending on pace, route, and stops. To fully absorb scenery, allow a half day. For slower pace or side detours, you might stretch to a full day.
I found no record of formal guided tours or audio guides for Kasi Hell Valley in English. Some local guides or trekking companies might provide Chinese or bilingual hiking assistance. It's best to inquire locally or via tour operators based around Yading / Daocheng.

A sample route:
No evidence was found of night visits, light shows, or organized nighttime tours in Kasi Hell Valley. It is primarily a daytime hiking/nature experience.
Because Kasi Hell Valley is relatively off the beaten path, it is not usually crowded. The least crowded times are weekday mornings, outside peak summer holiday periods.
Facilities are minimal given the remote nature. You may find basic amenities in Kasi Village (trailhead) — small shops, local services. Inside the canyon, rest spots may be informal; carry food, water, first aid, and basics.
The canyon trail involves uneven terrain, river crossings, possible steep stretches. Elderly or mobility-impaired visitors may find sections challenging. Children (fit and supervised) can do portions of the hike; select route segments according to ability. Disabled access (wheelchairs, etc.) is unlikely feasible for most canyon trail parts.
In remote regions like this, cash (RMB) is the safer option. In villages or service points, mobile payment (WeChat Pay, Alipay) may or may not be supported — don’t rely solely on cards or mobile if you are deep in the canyon.
Around Kasi Village you may find local Tibetan / Chinese village inns, tea houses, simple restaurants serving local food. Beyond that, inside the canyon there are no guaranteed restaurants.
Specific vegetarian/vegan/halal establishments are not well documented. You may be able to request simple vegetable or tofu dishes in local village eateries.
Accommodations are available in Daocheng / Yading area (guesthouses, lodges) which serve as base for exploring Kasi Canyon. Also lodging in Kasi Village or nearby villages might be possible in simple local inns.
Good companions:
In villages (Kasi, Daocheng / Yading) you may find small shops selling Tibetan handicrafts (prayer flags, jewelry, yak wool goods, prayer wheels, local textiles) and postcards.
After exploring Kasi Canyon, you return to Daocheng / Yading area by the same road/vehicle arrangements. From Daocheng you can continue onward by road or by flights (Daocheng Yading Airport) to other destinations in Sichuan or Tibet border regions.
