Fansipan, at 3,143 metres, can be climbed on foot, and for many trekkers this is the real reason to come to Sa Pa. The routes lead through the Hoang Lien National Park, from broadleaf forest into bamboo and then stunted alpine vegetation, finishing on the summit where the cable car complex now stands. The trek on this page is a one-day guided climb, which means a very early start and a long, steep day with a descent to finish. Many people prefer the two-day version with a night at a basic camp, which spreads the effort. You walk with a guide and usually porters or a support team, and you need to be properly fit, with sturdy boots, warm and waterproof clothing and a good head for long uphill days. It is not a technical climb, but it is steep, can be wet and cold, and can be dangerous in bad weather. Autumn is a favourable season, with clearer skies and less rain than summer.
Be honest with yourself about fitness. A one-day ascent and descent is a very long day, with hours of steady climbing on rough, rooty and sometimes slippery trail. If you are not used to this, choose a two-day itinerary or take the cable car instead. Check what the tour includes, from permits and park fees to meals, guides and transport to the trailhead, and ask how the operator handles bad weather.
Weather is the main risk. The summit is cold, windy and often in cloud, and temperatures can drop sharply, so pack a warm layer, a waterproof shell, gloves and a hat, even in autumn. Winter, from roughly December, can bring ice and freezing temperatures, and the trail may be restricted or closed in extreme conditions. Always follow the guide's decision to turn back.
Choose an operator that employs local guides and porters, pays them fairly and respects the park rules. Carry out your rubbish, stay on the trail and do not leave food. If you only want the view, the cable car is far easier. If you want the mountain itself, this is the real thing, and a descent after sunrise from an overnight camp is a memorable way to finish.

Good questions
How hard is the Fansipan trek?+
It is steep and long, with roots, rocks and mud on the trail. You do not need technical skills, but you do need strong fitness and good boots.
Can I do it in one day?+
Yes, guided one-day climbs exist, but they are a very long day. A two-day trek with a night at camp is easier on the body.
Do I need a guide?+
Going with a licensed guide is the norm and strongly advised. A guide also handles route finding, safety and weather decisions.
What is the weather like on the summit?+
Cold, windy and often cloudy, even in autumn. Pack warm and waterproof layers.
Is the cable car an alternative?+
Yes, the cable car reaches a stairway to the summit in about fifteen minutes. It is a very different experience from the trek.
