Are you thinking of hiking Cerro Chirripo National Park? This is the highest mountain in Costa Rica at 3,820 meters (12,533 feet). This national park covers 50 thousand hectares (123,552.69 acres) of land. So if you are not sure about what to expect, go ahead and check out our following post:  Complete Guide to Hiking Cerro Chirripo National Park, Costa Rica and then  make your reservation for this amazing national park!

You’ll need to make your reservation with the local association (Consorcio Aguas Eternas). Reservations can be made up to 6 months before your desired hiking date. However, from my perspective, it’s not simple to make a reservation for Chirripo. And it could be worse when you live outside of Costa Rica.

What makes it so complicated? Well, here are some things that I noticed when I made our reservation: 

1. Looking for availability

Booking your own spaces through the SINAC website can be a little bit frustrating. Actually, from our perspective, this website is  NOT completely user-friendly. The main problem shows up at the moment when SINAC releases the spaces for the high season. Everyone logs on at once trying to get the spot they want.

For example: When I (Rodrigo) was planning to make the reservation for my group, the day that administration of the park (SINAC) released the spaces online, there were over 80 users connected! So the website kept crashing as I was trying to reserve spaces. I was like: What the heck is this?

So, I tried MANY TIMES before getting our 4 spaces (me, Ligia, Jafeth and Mainor). Mainly because I was trying to book for Semana Santa ( Easter). All the Ticos (Costa Ricans) definitely wanted to go the same days.

2. Completing the process

When you are making your reservation, you’ll need to have the complete name and ID or passport number of every person who is going. Unfortunately, I did not know this. So, while I was in the process of booking spots, I had to call everyone and ask for their personal information!

3. Final payments

This is the payment just for the entrance fee to the park! Many countries have different prices for an entrance fee to a national park depending on where you’re from. Costa Rica is no exception. The price for locals is ₡4000 colones ($8.00 US) per day and the price for foreigners is $18.00 US per day. However, this payment is not a problem because you can put your credit card number right away on the website and that will be processed.

The part where it gets a little inconvenient is at the moment when you need to do the payment for the accommodations and food at the base camp. But DON’T WORRY! Here are some helpful steps and tips for making your reservation successfully.

Steps for making your reservation for Cerro Chirripo

You have probably noticed that there is not much information on the web about making your reservation for Cerro Chirripo. We had to ask some friends and call Aguas Eternas Consorcio, which was frustrating for us because sometimes they did not answer the phone.

However, it doesn’t have to be so hard for you.

Step #1: Registering and doing the reservation

Instead of doing a huge explanation here about how to make your reservation on the website of SINAC Costa Rica, up to the moment where you can put the credit card number for the payment of the entrance fee, we will share the following video to help guide you through the process:

Step #2: Confirmation of spaces

As soon the payment is done on the website of SINAC, you’ll get an email confirmation sent to your inbox (of the email that you use for registration).

That should come from, and it looks something like this:

Step #3 & Last but least: Payment of lodging and food

Consorcio Aguas Eternas will send an email for processing the payment of your lodging and food at the base camp. Now, for those who have not arrived in Costa Rica, make sure to clarify this information with Consorcio and explain when you’ll be arriving.

Unfortunately, the website of Consorcio is not set up yet for the process the payment for people who are outside of Costa Rica. But, when we talked with the administration of Conosorcio, they said that they hold the reservation until the moment that the clients arrive in the country and process the payment then.

So it’s very important to communicate with them to make sure your reservation and payment goes through.

  1. I would like to climb Cerro Chirripo May first or second. I can not find way to make my reservation.
    Please help.

  2. In the availability page, where it says “Disponibilidad” does that mean remaining online permits available? And where it says “Visita diaria”, does it mean remaining in-person permits available?

    • Hello Hunter, where it says “Disponibilidad” that means the number of persons that can visit the park but at the same time the number beds that are available in the base camp. Where it says “Visita diaria” means the number of people that can access the park but they will not have space at the base camp and they cannot even buy food at that place. If you have any other question send us an email to we will happy to help you.

  3. Hello Rodrigo,
    in case i manage to buy a permit online (6 months prior to my arrival) is it really possible to pay for the lodging when I arrive to Costa Rica in person at Banco National? Will the park hold and guarantee my reservation? Many thanks.

  4. hi – I have made a reservation to enter the park for 2 days but when I email my reservation details to I do not receive a reply. Any idea how I can ensure I get a reservation at the base camp or do they usually take many days to reply?!


    • Hi, Andy.-That’s the correct email for making the reservation at the base camp. If you want, you can email us your reservation number so we can help you to find out, why they have not answered back to you. Regards.

  5. Hello,

    I just tried making reservations on the website and each time it told me that my payment did not go through. I checked my bank account and I see that I have been charged SIX TIMES! I have tried calling the office, but my call does not go through (I am calling from the United States).

    Can someone please contact me as soon as possible to resolve this?

    • Hello, AJ.

      I am sorry to heard that, we don’t work directly with the national park office, however, let me see if can contact them. I will email you, so we can talk more about it.

  6. Hello,

    I am trying to reserve a spot online for el chirripo but continually receive a message on the “purchase confirmation” tab that my information is invalid. I put the names of the party under “complete name” and the corresponding passport numbers under “identification.” Under the pay data I enter all the information except I am unsure what the ID number is for. I am not a Costa Rican resident and tried putting in my passport number. What is the ID number?

    I’ve tried emailing SINAC multiple times but haven’t received a reply yet. Thank you in advance for your help!


    • Hello Matt,

      We don’t really understand what it happened with SINAC website. Since last week, we have received different emails and comment regarding the same error.

      We tried to contact them through the phone for asking about it but they didn’t answer our calls.

      The ID number could be your passport, drivers license or nationality identification.

      We will continue calling them and see if they explain to us what it is happening with their website. So we will let you know.

      Unfortunately, we don’t work directly with them since they are an independent institution from the government.


      • Rodrigo,

        Thanks for the reply and reaching out to SINAC. I will continue to watch for updates regarding their website and making reservations. I appreciate your help thus far.


  7. Hello! We have had the similar experience as AJ. We followed the instructions online for park entry permits. We submitted it but it didn’t seem to go through because we didn’t receive a confirmation number. We did that three times and our credit card was charged three times as well. We have sent multiple emails asking for a confirmation number, but no luck. We actually spoke to someone who said to email again with our names and passport numbers to get that confirmation number. Again no luck. We talked with Crestones base camp and they will not give us reservations to stay the 2 nights we need until we have that number. We are coming from the US just to do this hike. We have an 8 year old who is very excited. We do not speak Spanish very well so not sure what to do. Any advice would be appreciated!

    • Hello Charlotte Ditty

      Where you able to contact SINAC? Apparently, their help and customer service support email is

      I contacted them 3 days ago and they explained to me that their website is working fine for now.

      Did you get your money back? Unfortunately, we are just a travel blog who provides helpful information about Chirripo and we try to do our best, answering comments and email. We don’t work directly with SINAC, so we don’t understand why their system is working so bad.

      About your kid of 8 years old, I will say that while I visited Chirripo back in April 2017, I didn’t see any kid hiking up to Chirripo that does not mean that it can not be done with a kid of that age. However, I think it will be a little bit difficult and exhausted for the kid. At least if he/she has a great condition.

  8. Hi there Rodrigo

    I was hoping you would be nice enough to see if you could somehow help me to book?
    I realize you don’t work with SINAC…so any help you might be able to provide would be greatly appreciated.

    I checked the availability of the days that I would like to go, and it looks like there are available spots.
    However, when I try and add the admission…I get the following error message:
    The purchase can not be processed because the number of admissions generates aggregate sector overload

    Any thoughts?

    Thanks so much,

    PS….loving your blog thus far!

  9. Hi there!

    I wrote a message earlier…but it doesn’t seem to have gotten through… hoping this isn’t a duplicate though!

    Wondering if you would be able to help me out with a booking issue I seem to be having on the SINAC website.

    I checked the availability of the dates that I would like to go, and it looks like there are spots available…. however, when I try and add the admission, I get an error message saying:
    The purchase can not be processed because the number of admissions generates aggregate sector overload

    Any ideas?

    Thank you!

    • Hey Jonathan,

      Hope you are doing well.

      Don’t worry about the duplicate message. Actually, we need to approve the comments before they go through, this happens because we get a lot of Spam comments on our website.

      I can try to help you to book your entrance for Chirripo but I will need to know information like:

      -Number of people
      -IDs or Passport numbers
      -Dates (Nights at base camp)
      -Credit card or debit card number

      Unfortunately, I can not tell why SINAC’s website has a lot of errors. Many people have contacted us and eventually, we have told them that we can help with their reservations or they can contact SINAC through their email or phone.

      Let me know what you think about it.


  10. Thank you.
    Your description helped us, yesterday we tried 10 times and did not go, now it worked. I am grateful for the description.
    kindly regards from Germany

  11. Hey Rodrigo!

    I have recently reserved a park permit, and have received my authorization, reference, and terminal number via email. I followed up by emailing “” with my reservation details, the date I expect to enter Costa Rica and the date I could be expected to pay for lodging at Crestones base camp. I have not heard anything back, and I notice on the website that I have 48 hours from booking my permit to paying for accommodations or my reservation will be lost. Could you clarify this? Other than e-transfer or visa billing (and all I see is a bank number for a bank transfer), I don’t see how I can pay for lodging… Suggestions?



    • Hello James!

      Don’t worry about the 48 hours that they mentioned in their website for processing the payment for accommodation. I have asked them before about this and they have said that for reservation of foreigners works differently.

      If you give me your confirmation number, I can try to call them and make sure they got your email, so they can answer back to you and eventually you can continue talking with them.

      Let me know your confirmation number and when you sent the email to them.


  12. Hello and regards,
    A friend and I are hoping to climb Chirripo starting March 1 and returning March 2 (2019).
    I have tried the website for SINAC but it does not appear to be working. Additionally I have emailed them and called the office but no answer. Is there any other way around this to secure permits?
    I very much appreciate your help!
    -Safe travels,
