After researching somemore and rereading the posts here, it seems still can do the 西海大峡谷(West Sea Canyon), but just cannot do full loop.
I have a question regarding breakfast, lunch and dinner during the hike. Are there a lot of food stores along the hiking routes? And what time do the stores close? I dun really want to pay $50-60 for meals, like wat alexljy mentioned in his experience, haha.
Yes, that's what I meant, can still do West, only by to-fro, either leg or both. Given a choice if limited time, I suggest the leg via the north sea first, starting with a 800 steps 150m elevation stairwell from Baiyun to Bright Hill, when you are all fired up after breakfast.
If you set off early 8am, can be back leisurely by 2pm, leaving 4 hrs for the other to-fro leg (partial). The 2nd leg starting downhill from Baiyun is kinder physically. Just be sure to be back at baiyun before 645pm, before the $10 cookhouse chaipng (diy-served on alumimium trays) closes. (check again when there, seasonal closure times). Fret not, the hotels' minimarts/provision stalls, with seating/tables, opens 6am, sells maggi, hotdogs, eggs, hotsoups, corn, beer and drinks till 10-11pm for you to chill out alfresco.
Both legs of the more desolated west sea in 2012, only a couple small stalls selling snacks along the way. Take yr breakfast/lunch/dinner at brighthill or baiyun. Pack bread/biscuit/tumbler/apple with you for stoppages' bites.
Be warned, the climbs, mostly stairways, up and down numerous 100-200 m elevations, will really make you kpkb. Take it in good sense/stride, of fitness building, and you'll be back heroes (either totally konged or overly energized by end of evening. (my 5yo did it 1.5 legs single day with us). If bringing a kid there, when discouraged, play some mindgames with them, like challenge racing up every few flights of steps, more likely they win, but be sure/fit to provide some competitive challenge. Buy him/her a Huangshan gold medal, available at stalls, with name engraved at the end of trip.
Do not wear/carry too heavy wear to immobilise/'clumsify' yourselves, your climbs will keep you warm. Don't dress too satki, Northface and gears all over. Within 1 hour on 1st leg, you'll be stripping, sweating and swearing, swearing along with other tourists both going up or down, some with heels and suitcases. Each with a ******* face, will be asking each other going opposite directions, 'how long/far more?' very funny wan. But dun worry, the cool/cold, sunny, clear weather, skies and views and beautiful foliage/rocks formations, makes you feel all energized.
Bring a small pair of binos, and be sure to check out every lookout signage/points along the way. 2 days later your legs will ache like mad, good to nuay when back in Shanghai/Hangzhou.
