Most travel articles about Machu Picchu misidentify which altitude will affect you. The ruins sit at 2,430 metres above sea level — a moderate elevation that rarely causes problems. Cusco, where almost every visitor spends two to three days before heading to the site, sits at 3,400 metres. That 970-metre difference matters. The standard itinerary actually works in your favour: you acclimatise in Cusco, then descend to Machu Picchu, gaining relief rather than facing additional altitude stress. Plan your trip around Cusco's elevation, not the ruins'.
How to get from Cusco to Aguas Calientes: train vs. budget alternatives
The train from Cusco (or more commonly from Ollantaytambo in the Sacred Valley, 90 minutes from Cusco) to Aguas Calientes is the standard route. PeruRail and Inca Rail operate the main services. Journey time from Ollantaytambo is 1.5 to 2 hours; from Cusco city centre it's 3.5 to 4 hours. Expect to pay €40–120 one way depending on train class and season. Book at perurail.com or incarail.com at least 6 to 8 weeks ahead in peak season (June–August, September). Trains during these months sell out completely.
The budget alternative exists and is genuinely cheaper, but not scenic despite what some trekking companies claim. A minibus departs Cusco for Santa Teresa (6 hours, €8), followed by a taxi or shared pickup to the hydroelectric station (1 hour, €5), then walking along the train tracks to Aguas Calientes (2 hours, flat, hot). Total cost: €15–20 and 9–10 hours of travel. This route is functional and used by locals and genuine budget travellers. Use it only if train prices exceed your budget; don't expect landscape rewards.
A third option is to trek into the site rather than travel by train. The Inca Trail and Salkantay Trek both end at Machu Picchu (or Aguas Calientes), bypassing the train altogether. These require separate booking, permits in some cases, and 4–5 days of walking. They're covered separately below.
When and how to book Machu Picchu tickets
Book tickets exclusively at machupicchu.gob.pe, the official government portal. No resellers, no trekking companies as intermediaries — the government site is cheapest and most reliable. The site operates under a daily cap: 4,500 tickets per day, divided into several time slots. Tickets sell out completely from June through August, often by early January for peak dates. For travel in June–August, book by March at the latest. May and September typically have availability until April.
The site is divided into four circuits determined by your entry point and route. Circuit 1 (€50 adults, valid 6am–9am) is the standard first-time choice: it covers the Inti Watana (the astronomical stone in the ceremonial complex) and the Temple of the Sun. The famous postcard angle — the Sun Gate view — is reached within Circuit 1 by walking the upper agricultural terraces, roughly ten minutes from the entrance. Book Circuit 1 unless you have specific reasons to explore other circuits.
The Sun Gate (Inti Punku) adds an extra €10 and extends your visit by 45 minutes with a steep hike to the north. The panoramic view of the entire site from above justifies the cost if you want comprehensive photography. Huayna Picchu, the peak directly behind the ruins in every iconic photograph, requires a separate €10 permit and is limited to 400 tickets per day. It sells out months ahead for peak season. If you book it and get the ticket, the 45-minute climb (and descent) is worth it; the view is substantially better than the main site.
Timing your visit on the day
Machu Picchu is far less crowded before 9am. The 6am–9am time slot catches the site before the first wave of guided tours arrives on buses from Aguas Calientes (departures 5:30am–6:00am onwards). If you book an early slot, you'll spend your first 90 minutes in relative quiet. Most visitors arrive at 9am or later and immediately encounter 500+ other people at the Sun Gate viewpoint.
The site sits in a cloud forest. Morning light is typically clear; clouds build by 10am. By 11am, the entire site can disappear into mist. This dissipates by 3pm. If photography or clear views are priorities, arrive at 6am. If crowds are your main concern and you don't mind clouds, a 9am slot with heavy crowds is paradoxically less claustrophobic because the site is so large (32,000 square metres).
How to get from Aguas Calientes to the ruins
Two options: a shuttle bus or walking. The bus costs €24 return and takes 25 minutes each way on a steep switchback road. Buses depart Aguas Calientes from the main bus station near the train platform starting at 5:30am, timed to meet the 6am entry slot. The walking trail (1.5–2 hours uphill, steep, roughly 2,000 steps) saves the €24 but leaves your legs exhausted before you've spent 2–3 hours exploring the site itself. Walk it on the descent if you must; the buses run until 4pm.
Aguas Calientes: what to expect
Aguas Calientes is a single strip of guest houses, restaurants, and tour operators built around the train station. There's no town centre, no plaza, no character. Prices reflect captive-audience economics: a basic dinner costs €12–18. A hot chocolate and pastry runs €6–8. You need to stay here one night if you want the 6am entry slot; otherwise, return to Cusco the same day via an afternoon or evening train. A single night is sufficient. Don't plan leisure time here. The town exists to move people to and from the site.
What the site itself demands of you
Two major mistakes plague most visits. First: entering at 9am, spending 90 minutes photographing from the Sun Gate and residential area (the western section), then leaving after 2–3 hours. This covers perhaps one-third of the site. Second: underestimating the walking required. The full Circuit 1 includes the upper agricultural terraces, the ceremonial complex with the Inti Watana and Temple of the Sun, the residential district (east side, steeper, fewer tourists), and the lower temples. Plan for 2.5–3 hours of sustained walking on stone steps, many of them worn smooth by centuries of use. Wear proper walking shoes. The site has no railings or barriers; steep drops are common.
The llamas and alpacas that wander the site are not staged attractions; they live there. They're accustomed to people and will eat paper, maps, and food if you leave it unattended. They're not aggressive, merely curious and persistent.
Cloud timing is unpredictable year to year, but the pattern is consistent: clear mornings, cloud build-up by mid-morning, often clearing again in the afternoon. If you see clouds at 10am, return to a lower-elevation viewpoint and wait; they often disperse by 3pm.
The Inca Trail and Salkantay Trek alternatives
The Inca Trail is the historical route, a 43-kilometre, four-day trek through the Sacred Valley ending at Machu Picchu's Sun Gate at dawn. You enter the site with the first light, before buses arrive. The trail passes Wiñay Wayna, a remote and intact Inca settlement on the mountainside.
A permit is required (500 trekkers per day maximum) and must be booked through a licensed operator at least 4 months ahead. June–August slots often sell out by January. Minimum cost: €700 per person including guide, cook, porters, and camping. The trek involves three mountain passes, the highest at 4,200 metres. It's moderately difficult, not extreme, but requires reasonable fitness and acclimatisation to Cusco's altitude first.
The Salkantay Trek is the non-permit alternative: five days, higher altitude (Salkantay Pass at 4,600 metres), physically harder, and ending at Aguas Calientes (not the Sun Gate). Cost: €400–600 including guide. It's the choice for trekkers who don't book early enough or prefer higher-altitude challenge. It avoids the permit bottleneck but involves greater physical difficulty.
Both treks are booked through Cusco-based operators. Book 3–4 months ahead for June–August; 4–6 weeks ahead for shoulder seasons (May, September).
When to visit: seasonal patterns
The dry season (May–October) offers clear skies and dry trails. It's also peak season for crowds and prices. June–August is the absolute peak: every train and ticket slot is booked, and the site sustains 4,000–4,500 visitors daily. Prices are 30–50% higher than shoulder seasons.
The wet season (November–April) brings rain, muddy trails, and cloud cover. Some days the site is entirely cloud-shrouded. However, crowds drop dramatically and prices fall 20–30%. March has the heaviest rainfall. The season is traversable, not ideal.
The best windows are May and September. May sits at the start of the dry season with clear skies developing. Crowds are light compared to June. September is the tail end of dry season, drying out after winter rains, with post-August rush absent. Both months offer a genuine balance: reasonable weather, manageable crowds, and prices 10–15% above low season but 20% below peak.
Machu Picchu is for the planned traveller
Book Machu Picchu if you're history-focused, can commit to booking 3–4 months ahead, and have moderate fitness for sustained walking on steep stone steps. Visit in May or September for the best combination of weather, crowds, and price. Book train tickets first (at least 6 weeks ahead), then site tickets (at least 8 weeks ahead, longer for peak season). Arrive in Cusco, spend 2–3 days acclimatising, then travel to the Sacred Valley or direct to Ollantaytambo. Take the train in early morning. Spend a full day at the site. Return by train the same afternoon or the following day. This timeline is tight but standard. Trying to book fewer than 8 weeks ahead in peak season is a strategy that fails.
