I guided around there at the weekend and pretty sure this is an accurate description of conditions at the moment (Sept 14th 2011).
Note the link below to Wenshan Hot Spring photos…OFFICIALLY OPEN!
Starting from Tienxiang, instead of Baiyang, or Baiyang Alternative, I would recommend the local temple and Lyushui-Heliou for easy hikes. For tougher, but superb, hiking consider Wenshan Hot Springs then Wenshan-Lyushui.
Tienxiang is generally a great place to stay. But recently I have seen advantages of staying just outside the gorge - consider having a bike rental guy drive you and a bicycle up the gorge (to Tienxiang or Huitouwan), hike one of the significant trails, and then come back to your bike locked at the trailhead/other trail exit. This way you have the freedom to explore the gorge at your own pace, with very little pedaling. Bike + shuttle around $700. picasaweb.google.com/barkingdee … directlink
Dekalun Trail (得卡倫步道). Up the hill behind the National Park headquarters. Open. Less than 1 hour’s strolling, tougher, longer hiking options.
Dali-Datong Trail (大禮大同步道) Long, scenic single-day, or couple days. Chingshui 3 days. All trail options open.
Shakadang (砂卡礑步道). A very pleasant must-do hike, starts after tunnel not far from National Park HQ. Open. Was closed start of last week further in, open now.
Eternal Spring Shrine Trail (Changchun, 長春祠步道). Do the 40-minute loop hike up above the shrine exiting at the nearby Changuang Temple. Few people get beyond the car park. Open.
Buluowan Trail (布洛灣－燕子口步道). A good steep path to use down to the main highway - especially if staying at the Leader Hotel. Open.
Swallow’s Grotto Trail (Yanzihkou, 布洛灣－燕子口步道). A very easy stroll that should NOT on any account be missed. Usually open, occasionally closed due to loose falling rocks. If riding down the gorge on bicycle consider riding against the traffic/Chinese tourists.
Jhuilu (Vertigo) Trail (錐麓古道) is now open its entire length. Unbeatable! See pictures. Needs both kinds of permits.
Tunnel of Nine Turns Trail（Jiuqudong, 九曲洞步道). A stunning, easy stroll. Currently closed. Really closed.
Lyushui-Heliou Trail (綠水步道). A very pleasant less than 1-hour loop. The nest are usually for ants not wasps. Open.
Lyushui - Wenshan Trail (綠水文山步道) A recently reopened trail. Moderately tough - at start and end some scrambling, and requires/deserves 4 to 5 hours. Permit required but easy to obtain from the the NP police (warden) station at the park headquarters or at Tienxiang (the station on the left going up the hill towards the protestant church…across the street from the regular police station!). Best done starting from Wenshan. Open.
Baiyang Trail (白楊步道). A very, very nice trail, CLOSED due to damage to mountainside at entrance next to highway. Tunnel entrance seems to be REALLY closed. Usually no traffic restrictions here - construction work going on at the moment does not require it. If restrictions, as mentioned, open on the hour for 10 minutes. Holidays and outside work hours is open.
Tianxiang - Baiyang Trail (天祥─白楊步道). Recently reopened access to the Baiyang Trail. Toughish and potentially risky in places. Trail starts from the protestant church in Tienxiang village. Now well signposted “Baiyang Alternative Route” Please get a permit (easy) from the nearby police station. Easy walking once you get to the original trail that ends at the fun ‘Water Curtain tunnel’. If possible bring a flashlight for the tunnels. Allow 5-6 hours. Open, bit a previous poster mentioned the last bridge (will be rebuilt within a year) is out and you can’t view the waterfall. Skip it for the moment.
Huoran Pavilion Trail. Closed
Wenshan Hot Springs (文山溫泉). OPEN. OPEN. OPEN see photos and comments at picasaweb.google.com/barkingdee … directlink
Meiyuan Jhucun Trail (梅園竹村). Great 6-hour, fairly-flat path. Officially closed due to landslide damage after the turn of for Lianhua Pond. Usually passable.
Lianhua Pond (Lotus, 蓮花池步道). A very nice 3-hour round hike starting and ending at Huitouwan (6km beyond Tienxiang Village. Don’t get too distracted by the views and walk of the edge. Open. Consider tough scrambling extension up to Zhulun Mountain.
