Green Guardians of the Forest

Get involved with the recovery of ecologically degraded areas through the restitution of native forests to restore ecological systems and promote biodiversity in the Sintra-Cascais Natural Park!

Are you a true nature lover and care a lot for the preservation of our forests and the protection of our natural habitat? Then this really is the perfect program for you! Spend a whole morning surrounded by beautiful nature and get involved with the recovery of ecologically degraded areas through the restitution of native forests. The perfect program to manifest your love for our natural environment! Depending on the current intervention needs of each respective location as well as the time of the year, you will have the chance to carry out the following activities:

Control of exotic weed species | Removal of exotic species that pose a threat to biodiversity and forests. 

Maintenance of reforested areas | Taking care of previously planted plants.

Protection of spontaneous regeneration | Identifying spontaneously arisen plants that need to be preserved due to their importance for the biodiversity and local gene bank.

Fire protection | Management of thin and thick plant material to reduce the combustion load.

Planting to promote regeneration | Plantations that allow for the restitution of native biodiverse forests to promote natural regeneration processes.

Restoration of water lines | Restoration of the characteristic habitats associated with riparian galleries.

Natural engineering works | Construction of palisades to control lines of torrential runoff or for the creation of wetlands as well as barriers to prevent erosion, among others.

All of the above-described activities will not only teach you everything you need to know about the existent species in the Sintra Cascais Natural Park but will also provide you with the specific know-how on how to preserve them. The activities will help you get to know the available approaches to prevent fires as well as the existing ideas for the prosperity of the species and growth of the fauna and flora of the park.

Shall I bring any own equipment and tools for this program?

No, you will be provided with all the tools and materials you'll need for this program at the location! 

Am I provided with insurance during my stay?

Your program fee includes civil liability insurance with limited coverage, that only covers accidents that may happen during your volunteering shift.

We highly recommend you to get full health, travel and accidents insurance in your home country!

Are children allowed to join this volunteer program?

Yes, children are also allowed to take part in this program, if they are accompanied by their parents or legal representative!

Do I need to book my stay well in advance?

No, not necessarily! Depending on the current availability of the program of your choice, we may even be able to accommodate your stay and participation for the upcoming week! However, both in our responsible travel experiences and our volunteer programs as well as regarding our available beds in the hostel, we do sometimes reach our full capacity and therefore recommend booking your stay with us as early as possible to secure your spot!  

Do I need to speak the local language?

No, you don't need to have any previous skills in the local language! All of our programs are run entirely in English and our guides and staff are all comfortable speaking English as well! But we always encourage our participants to get acquainted with some of the most basic terms and expressions, as even just a simple "Good morning!" in the local language can be a great icebreaker to start interacting with the locals! 

There are also language lessons available for volunteers. The language lessons can be booked before or on the arrival. Lessons are taught by a professional teacher and tailored to each volunteer’s current language level.


Does this experience include food and beverages?

Yes, there will be food and drinks provided during this experience! Feel free to take a look at our itinerary, experience description and pricing info for more detailed information on what you can expect!

Does this experience include the transportation from my accommodation?

No, your transportation is not included, but we can offer this service for an extra cost! Just shoot us an email and let us know the exact time and location, and we'll be there on time! 

Does this program require a high level of physical fitness?

No! All activities within this program only require a medium or low level of physical fitness! 

I have special dietary requirements! Will I find food options that cater my needs?

Yes, if you are vegetarian or have specific food intolerances, we will be able to adapt the food offered to meet your dietary needs. Please get in touch with us as early as possible so we can make all necessary arrangements! 

Is accommodation also included in this experience fee?

No, accommodation is not included in this trip. You'll need to organize your own accommodation, but we are happy to assist you in finding a suitable one if you like! Feel free to get in touch with us!

What is ImpacTrip's Cancellation and Refund Policy?

Impactrip deposit fees are designed to be as affordable as possible to allow everyone to join our programs. Therefore, considering its limited capacity and the expectations of everyone involved, ImpacTrip is unable to provide a total refund policy.

Deposit Fee

The payment of the deposit fees confirms a volunteer’s acceptance onto one of ImpacTrip's volunteer programs. Deposit fees are not transferable to other people but may be transferable to another program.

The deposit fee is refundable until sixty days before the start date of the volunteer’s chosen program. Requests for deposit fee refunds must be made via an email to your ImpacTrip Booking Manager, clearly detailing the reasons for cancellation.

Cancellations are subject to the following policies:

  • The notice period is based on the earliest start date the volunteer has ever been registered for.
  • If a volunteer cancels sixty days or more before their earliest program start date, they can request a refund of the deposit fee, which will be provided minus the transaction costs of the refund. Alternatively, they may ask for a deposit fee credit to be held in their name for future use on any ImpacTrip program, subject to availability, for a period of twelve months from their earliest registered start date. This credit may be issued minus the value of any change fees the volunteer has incurred.
  • If a volunteer cancels between fifty-nine and thirty days before their program’s start date, no refund of the deposit fee is available. A deposit fee credit may be held in their name for a period of twelve months from their earliest registered start date, for future use on another ImpacTrip program, subject to program availability and at the discretion of the Impactrip Booking Manager.
  • If a volunteer cancels less than thirty days before their programs start date, no refund of any fees is available. A deposit fee credit may be held in their name for twelve months from their earliest registered start date, subject to availability, provided deposit fees have been paid in full by their due date.

Where a group of ten or more people is volunteering with ImpacTrip, the group leader must register ahead of other group members in order to secure the group’s dates and plans. Group members must then register no less than sixty days before the program starts. Group members who register less than sixty days before the program start date may be excluded from the program unless approved by ImpacTrip.

ImpacTrip reserves the right to revise its program fees at any time. All program fees revisions will be made via the ImpacTrip website. Program fee revisions are not applicable to volunteers who have already submitted their payment before the revisions are due to take effect. A volunteer’s placement on a program is not confirmed until the deposit fee has been paid in full and the availability has been confirmed by their ImpacTrip Booking Manager.
