*'''2025-08-26: Track file update 2025 and investigation suggestions of Jan Dudeck'''
- Option 1 (Rio Clarillo): Only recommended in northbound direction since Reserva Rio Clarillo does not permit a southbound traverse.
- New GPT01 Option 2 (Cerro Los Cristales): Natalie and Tomas suggested this route that connects GPT01 and GPT02 into one long hike. This route starts outside of national parks and reserves (Unlike GPT01 Option 1) therefore GPT01 Option 2 is feasible in southbound and northbound direction (Unlike GPT01 Option 1 that can only be hiked in northbound direction). This route is only recommended for experienced hikers that have vast experience in navigating in complex terrain. This option is not a suitable start for hikers that are not yet familiar with the GPT.
- Option 3 (Filo Purgatorio): Hikers that enjoy scrambling may opt for this very demanding route that ascents to the summit and descents in rocky terrain to the Regular Route.
- Option 4 (Rio Maipo): Bad weather option for diehard connecting footstep hikers.

==Season 2025/26==
* '''GPT01 | 2025-11-28 to 2025-11-29 | 1,5 days | Hiking | SOBO | Option 3 (Filo Purgatorio) - Option 3B - Option 3D - RR | Michaela '''
Camp: -33.635701, -70.424136
Total: 27,85km, elevation gain: 2.120 m, elevation loss: 1.933 m
Attraction: 3/5, Difficulty 3/5
Transport: I took a Uber to Escuela Básica San Juan de Pirque and started from there
Comment: I would take 5-6 Liters water for the first day. I found water the next day around noon and it was very hot. I really liked my camping spot with an amazing view down to Santiago.
* ''' GPT01 2025-11-15 to 2025-11-16/SOBO/RR/option 3 (Filo Purgatorio)/option 3B/option3D/RR/Denis Rosa/ Robert Hanulík '''
We went to last metro station link 4 and hiked from there. Good to take more water (we took 5,5l). There is water at the end of the option 3 (Filo Purgatorio).
We slept -33.62636, -70.44757 here, beautiful spot on the ridge.
I would recommend to take optional routes instead of RR.
Attractiveness 3/5
Difficulty 3/5
* '''GPT01/ 04-11-2025 to 06-11-2025 / 2 days / Hiking SOBO/ Route: Option 3 (Filo Purgatorio)- Option 3B-Option 3D- RR / Combined GPT01 and GPT02 / AthenaJones
'''
Transport: I took the train to Plaza de Puente Alto then I took an Uber to the beginning of Option 3. I heard there is a bus MB73 instead of Uber or walking.
Recommendations: Taking around 6 liters of water from town. A bug net would be nice to carry. Highly recommend Option 3B- the route to Cerro Purgatorio. I think the route would have been boring without this option though it is a more demanding route to ascend.
==Season 2024/25==
* '''GPT02+01 / 2025-04-02 to 2025-04-06 / 4 days / NOBO / RR + OH-TL-V {02-C} + OH-TL-V {01-02} / Tim & Tobias '''
We combined GPT02 + 01 through the new option OH-TL-V {01-02} over the ridge and ended up in El Principal. It is a great option, especially going NOBO, because of the stunning view towards Santiago. Going SOBO can be difficult with water supply. We were also lucky with the heat and water supply, since it was snowing 4 days before departure. Did not meet anyone during the 4 days of hiking. For creators: Camp ? {02-C} [0.6/2646] could be shifted to -33.86167 -70.42479. It is much safer in terms of wind protection. More details on wiki.
Day 1: Took the bus from Coya to the RR and startet walking NOBO 23 km to Camp ? {02} [72.2/1736]. There was little water there. No more water on the trail.
Day 2: Walked 23 km to Camp {02-D} [1.3/2800] without difficulty’s. A lot of boring primary road walking and it was pretty hot.
Day 3: Walked 20 km to Camp ? {02-C} [0.6/2646]. The water in the river has a taste of iron. It's best to bring some water. Beautiful trail along the mountains, water at all spots.
Day 4: 30 km Trailwalking to El Principal. Last water on the at -33.83214 -70.49216. Before arriving at the main road, there is a black gate at -33.73666 -70.55370. We managed to open the gate by pushing it down a bit. Took the bus to puente alto where we stayed at “Alojamiento Puente Alto”.
* '''2025-03-23 to 2025-03-24 / 20 hours/ Hiking / SOBO / New option from El Principal via Cerro Papagayo and Cruzada Las Hormigas to RR/ Tomáš'''
There can be no GPT season without going to GPT01, it seems, though this was my last idea for now. This option provides a TL and CC alternative to running paralel to the road-based RR, especially if you do not insist on connecting footsteps and take the bus from Puente Alto. However of all the options I did on GPT01, I liked this one the least. Bear in mind I never walked the RR, as I do not like roads, and assume this is still far superior to RR. However, I quite liked the last 7 km or so. It is partially in our suggestion in the November update but hopefully will be part of GPT25/26.
I took the MB-74 from Puente Alto at 20:20 after waiting for it for 50 minutes, almost giving up. It was the last bus that Sunday. It took me to end of 01A here: -33.71013, -70.53235. At the end of the road, I met a slightly drunk local resident, who was surprised by me. I explained I was going to the mountains. He warned me that if I meet anybody, they might think I am a ghost (""fantasma") and shoot me. I did not point out ghosts cannot be shot. It was night - he said that during the day it would be ok, the riverbed is public. I was a bit spooked and walked afterwards without a headlamp to evade attention, but I did not meet anybody anyway. Judging from Strava, it would have been better to get out a few hundred metres earlier at -33.70930, -70.53656. I crossed the river bed and cut across to here: -33.70045, -70.5316, climbing over an easy fence. Both Strava and OSM show a lot of traffic and trails. Not sure what the right of access is, but I assume it is permissive. One walks through a tree plantation (or vinyard?) that diverts a lot of water from Rio Clarrillo (which was itself dry) for its use through a system of mighty ditches. I walked for almost 2 km through here -33.69468, -70.52804, going through and around two gates here: -33.69258, -70.52659 and finally fording here -33.68755, -70.52263. By now it was around ten, I started to go up on a steep trail that was mostly quite clear even with a headlamp until about 1400m of altitude, where I camped after midnight. I started late because of arriving late to Santiago and having a flight home booked in less than two days, but a late start might be advisable anyway to escape the heat.
The next day I started early continuing up on a maintained trail. Around 1900 m at -33.66986, -70.48218, there is a cave with a spring. In late march it wasjust a puddle that would need to be filtered, but maybe there is running water earlier in the season. Once up the ridge, the visible trail continues traversing and going up slightly to -33.66459, -70.46427. From there, a faint somewhat steep but not exposed trail with a cairn here and there leads you to the top of Cerro Papagayo. From there, a few hundred metres are a bit rocky and almost exposed, but I just used my poles for balance, I have never needed to use my hands. Traverse under Cruzada Las Hormigas and climbing it is very easy, mostly trailess. From there I started going down, here and there finding a trail. Around 2100 m at -33.67901, -70.41957, I traversed to a ridge on the other side of the trail. Some care was needed, but it was not exposed. This ridge can be followed all the way to RR. I left the ridge twice, seeking greener pastures/better trails, but that is pointless, from -33.67573, -70.41742, it is best to go down the ridge to -33.68415, -70.38865, where Strava marks begin. The MR on RR is actually more like TL&MR. It used to be a road thay served to build a gas pipe unser it. It is not used by cars and it is heavily eroded. Met water -33.68331, -70.38512. 20 uproad from the water, I joined Strava marks to find a CC&TL way to the other side of the creek, reaching variant E at -33.68189, -70.38373. I think upper part of variant E does not really exist, I could not find where it is supposed to join the RR from above and saw nothing from below. From here, I followed Strava and OSM down, RR does not seem to be picked very sensibly. I had a bath, the only time where there were many wasps. I saw a tent here and there and some rubbish. mamy trails. I reached the busy (5 cars a minute?) road around five, quickly hitching to San Jose de Maipo, from where a bus is said to go to Puente Alto every 20-30 minutes. It was a cold day. I took 4 litres with me and fruits and vegetables and drank 3 litres - might be much harder in high summer. Some plants were still blossoming.
* ''' 2025-FEB-27 to 2025-MAR-01 / 2 days / Hiking / SOBO / RR / Farah & Jan'''
This was our last section of the GPT. For now…
<br>We did it in one full day and two relaxed half hiking days. Camped at S 33°38.4840’ W 70°26.9562’ and S 33°40.3236’ W 70°23.5408’
<br>The last 5 kilometers of the ascent are pretty steep, as is the first part of the descent. Ways are in good condition and easy to follow. There’s not much vegetation.
<br>Found more water sources than expected. Note that last winter had a lot of snow, so you can’t rely on these water sources in low or average snow years. Here are a few of them:<br>S 33°37.3970’ W 70°30.2264’<br>S 33°37.8949’ W 70°29.4920’<br>S 33°40.9963’ W 70°23.1090’<br>S 33°40.3226’ W 70°23.5491’
<br>Like Arno we saw an incredible amount of wasps along the way, especially close to water sources. Unlike him we can’t confirm they do no harm. Farah got stung in her buttock, Jan in his penis. Be careful when peeing! Apart from that no incidents.
==Regular Route==
No permit or entry fees apply to the regular route but a high gate was build in 2021. If the the gate at waypoint "X, Gate {01} [11.2/787]" is locked, continue 2.1 km on the main road and take Option 2 3 (Filo Purgatorio).
==Option 1 (Rio Clarillo)==
