Mardi Himal: An Honest Take on Nepal's Quietest High-Altitude Trek

What Mardi Himal Is and Why It Is Still Called "New"

Mardi Himal is a 5,587 m peak in the Annapurna massif, the eastern neighbour of Machhapuchhre (Fishtail). The trekking route to the base camp beneath this peak existed for decades as a shepherd's path, but it was officially opened to foreign trekkers only in March 2012, when Nepal's Ministry of Tourism added Mardi Himal Base Camp to the list of permitted routes in the Annapurna Conservation Area. By Himalayan standards, that is yesterday. The Annapurna Base Camp trail, for comparison, has been established since the late 1970s; ABC sees around 75,000 trekkers a year, while Mardi Himal draws approximately 10,000–15,000.

These figures are not marketing copy about "untouched wilderness". They mean something concrete: fewer lodges on the route, more limited menus at guesthouses, and a trail that in its upper sections is narrower and in places requires attention to navigation (although ACAP installed blue markers in 2018). In winter, snow can close the trail above Low Camp — without a guide or winter trekking experience, this is a serious risk.

What the Route Is Like Physically

The standard itinerary: Kande (1,770 m) → Forest Camp (2,550 m) → Low Camp (2,970 m) → High Camp (3,550 m) → Upper Viewpoint (4,200 m) → Mardi Himal Base Camp (4,500 m) and back via Siding (1,750 m) or down to Lumre. Total distance is about 40 km one way; realistic time is 5–6 net days with one acclimatisation day between Low Camp and High Camp.

This is not Annapurna Base Camp with its comfortable stone steps and relatively gentle transitions. Mardi Himal is a ridge route. After Low Camp you walk along a narrow crest with drop-offs on both sides. The trail is not technical in itself (no ropes required), but demands attention with every step, especially in wind or cloud. Daily stages average 4–7 hours at a steady pace.

Altitude and Acclimatisation — Where the Catch Is

The central challenge of Mardi Himal is the rate of altitude gain. From Kande to High Camp is 1,780 m over 2–3 days. If you push aggressively (some groups attempt Kande → Forest Camp → High Camp in two days), this violates the basic rule of "no more than 500 m/day above 3,000 m" (the standard recommendation of the Wilderness Medical Society). Acute Mountain Sickness (AMS) is encountered more frequently on this route than on ABC — precisely because of how compact it is.

Concrete numbers: the partial pressure of oxygen at 4,500 m is about 57% of sea-level values. Symptoms of mild AMS (headache, nausea, disturbed sleep) at this altitude occur in roughly 25–40% of people without prior acclimatisation. This is not a sign of poor fitness — it is physiology.

Our approach: at least one night at Low Camp (2,970 m), one night at High Camp (3,550 m), and one radial day hike to the Upper Viewpoint without carrying a full pack — the classic "climb high, sleep low" scheme. The ascent to Mardi Himal Base Camp itself at 4,500 m is short and is usually done on the morning of day four with a return to High Camp for the night.

What Makes Mardi Himal Interesting Beyond Being "Another Nepal Trek"

Three things set it apart from ABC and the Annapurna Circuit:

First: the view of the southern face of Annapurna and Machhapuchhre from a lateral angle. Most photographs of Annapurna are taken from the south-facing front (Poon Hill, Tadapani, ABC). From Mardi Himal you look at the same massif from the eastern ridge — a different geometry of shadows, a different sequence of summits, and Machhapuchhre visible in full rather than just as a "sharp tooth" from the south. For a landscape photographer this is a rare window of perspectives.

Second: the dense rhododendron forest between Forest Camp and Low Camp. Flowering season is late March to mid-April, with red, white and pink blossoms on trees up to 12 m tall. This is not cherry blossom and not a Swiss alpine meadow — it is a specific mid-mountain Nepali biome, and we recommend planning your trip specifically around the flowering season.

Third: the finish at Siding rather than returning through Kande. The descent into this village follows a trail through terraced fields, past Gurung homes, past tea shops with no display windows. Tourist infrastructure here is minimal. Compared with the lodges of Chomrong on the ABC route, where menus are printed in three languages and Wi-Fi is available, this is a different Nepal.

When to Go and Who This Suits

Best windows:

• Late September – late November — post-monsoon season, maximum visibility, nights at High Camp around −5 °C

• Late March – mid-May — pre-monsoon, rhododendrons in bloom, though by May daytime cloud builds on the upper sections

When not to go:

• Late June – mid-September (monsoon) — leeches on forested sections, the trail above Low Camp can be slippery, visibility is nearly zero

• January – February without winter experience — snow above Low Camp, temperatures at High Camp down to −15 °C at night, some lodges closed

Who this suits: those who have already done multi-day mountain routes at 2,500–3,500 m and understand how their body responds to altitude. This is not a first trek in Nepal — for that, Ghorepani–Poon Hill (3,210 m, 4 days) or shorter Annapurna sections are a better fit.

What to Understand Before Booking

Mardi Himal is not "easier" than Annapurna Base Camp, as some sources suggest. It is shorter and more compact, but that compactness means the altitude gain is steeper. Lodges are more basic. The trail is narrower in places. In winter the risks are higher. If this would be your first high-altitude trek, a different route is the better starting point. If you have baseline experience and want fewer people, sharper angles on Annapurna and the chance to photograph rhododendrons in full bloom — Mardi Himal is worth the time.
