NOTE: The program is available year round, except for the Sidney Island caches (which are disabled November 2015 - March 2016).

Awaken the treasure hunter inside you and join us for Gulf Islands National Park Reserve’s geocaching program. This year we have put a special "first to find" prize in EACH cache – a beautiful Parks Canada Geocoin!

Geocaching is an interactive treasure hunt played with a GPS unit. The park is pleased to offer two new geocaching loops that cater to different ages and abilities. The treasure hunt will take you to places on the islands you have never been and leave you without a doubt in your mind as to why this park is one of Canada’s national treasures.

The park's geocaching program is different from what you can expect to find when you are out geocaching in other areas. The program is more of a self-guided interpretation experience that provides you with an opportunity to learn about the unique natural and cultural heritage of the national park. Feel free to take the cache items provided by the park, but please don't leave trade items in park caches. "Leave no Trace™" is the motto when it comes to the national park reserve, and cachers are asked not to place their own caches in the park reserve.

Once you have completed your passport, you will receive one of the limited edition Parks Canada geocoins. So grab your GPS and come explore the Gulf Islands. Please note that the park geocaching program is available for the period between May to September.

Things to Know Before Getting Started

  1. Obtain all the co-ordinates for the geocaches from
  2. Use either a GPS, iPhone or Blackberry to find the caches (when using a smartphone, download the geocaching app).
  3. Respect the natural surroundings by staying on marked trails – all geocaches are directly accessible from trails or public areas.
  4. Do not leave anything (trade items) inside of the geocaches as they may attract wildlife.
  5. At this time, only Parks Canada staff may place geocaches in the park.
  6. If geocaching with a large number of people, split into groups of 15 or less. This is a precautionary policy to ensure adequate protection of the park’s natural and cultural heritage.
  7. Not sure how to geocache? Borrow a GPS and master the basics with the help of a park interpreter on a Geocaching 101 program. Check the website for program locations and times.
