Visitors should prepare full raincoats, umbrellas, warm clothes, anti-slip shoes, along with flashlights and power banks to cope with unfavorable weather conditions. At the same time, they should bring some basic medical supplies and drinking water for use when needed.
When thunderstorms, lightning or strong gusts of wind appear, it is necessary to quickly find a solid shelter, avoid standing under tall trees, near power poles, cliffs or open areas. Do not continue to move by motorbike or participate in outdoor activities until the weather stabilizes again.
In case of prolonged heavy rain, signs of landslides, rising water levels or functional agencies issuing dangerous warnings, tourists need to strictly comply with the instructions of local authorities. Proactively changing schedules or canceling sightseeing trips in high-risk areas will help ensure safety for themselves and their companions.
