重阳登高习俗流传两千余年 国家公园管理局列秋季登山安全要点
10月18日是农历九月初九重阳节。重阳又称重九节、登高节，源流可溯至汉代，唐朝起广泛流行。农历九月九日，月、日皆为九，「九九」与「久久」同音，寄托长寿之意；1989年起，重阳被定为敬老节。传统习俗包括登高、赏菊、饮菊花酒、吃重阳糕与佩戴茱萸。相传登高源于避灾传说：登上高处、饮菊花酒、佩茱萸以避祸，后世演变为秋日登高望远的节令活动。
在美国，秋日登高多与国家公园的秋季徒步重合。国家公园管理局（National Park Service，NPS）在其「Hike Smart」安全页面列明多项要点：出行前了解自身限度并查阅公园网站的野生动物信息；携带地图、饮水、防晒用品与照明等基本装备，手机手电筒不可靠，应备头灯；走干燥路径与 footing 稳固的岩石区域，远离急流与湿滑斜坡，在瀑布附近岩石上攀爬极其危险；查阅当地潮汐表并留意潮汐行为；喷驱虫剂并在徒步中与徒步后检查蜱虫；留意野生动物，妥善存放食物、不使用浓烈气味物品。
管理局同时提醒，登山前把路线与预计返回时间告知他人、在游客中心确认日落时间，也是其安全指引中的常规内容。今年重阳正日适逢星期日。

Climbing Heights for Chongyang: A 2,000-Year-Old Custom, and the National Park Service's Hike Smart Safety Points
October 18 is the Double Ninth Festival (Chongyang), observed on the ninth day of the ninth lunar month. With roots in ancient harvest celebrations and ancestor worship, the festival dates back more than 2,000 years and became widely celebrated during the Tang Dynasty (618–907). Because the pronunciation of 'double nine' sounds like the Chinese word for 'long-lasting,' the day symbolizes longevity and health, and in modern China it is also a day dedicated to respecting and caring for older adults, often called Senior Citizens' Day. Traditional customs include climbing mountains, admiring chrysanthemums, drinking chrysanthemum tea or wine, eating Chongyang cake, wearing zhuyu — a fragrant medicinal plant once believed to ward off illness — and honoring elders.
In the United States, the climbing custom overlaps with the autumn hiking season in the national parks. On its 'Hike Smart' safety page, the National Park Service (NPS) lists a series of points for hikers: know your limits and check the park's website to learn about its wildlife; carry essentials including a map, water, sun protection and a light — a phone flashlight is not reliable, so carry a headlamp; stick to dry paths and solid rock areas with good footing, and stay away from rapid waters and slippery slopes, as climbing on rocks near waterfalls is extremely dangerous; consult local tide tables and pay attention to tidal behavior where relevant; use repellent and check clothing and body for ticks during and after the hike; be aware of wildlife, store food properly and do not wear strong scents.
This year's festival day falls on a Sunday.
