The most Favorited Letterbox Hybrids on each continent

These are the most Favorited Letterbox Hybrids on each continent. Letterbox Hybrids are based on an older kind of container search, called letterboxing. Each letterbox contains a logbook, and a rubber stamp. From a cinema in Hong Kong, to a picturesque peak on the way to Machu Picchu, we’re highlighting the best places to send a postcard!

This is the fifth in a series about the most Favorited geocaches on each continent. Stay tuned next month for our next installment, and be sure to check out the previous versions of the most Favorited Virtuals, EarthCaches, Traditional Caches, and Multi-Caches.

Fes el Bali, or Old Fes, is the oldest walled section of Fez, Morocco. Originally founded between 789 and 808 AD, it is now listed as a UNESCO World Heritage site, and is the location of the most Favorited Letterbox in Africa. In addition to this Letterbox, the neighborhood is also home to the oldest university in the world, as well as a myriad of traditional shops and markets. Here’s looking at you, cache!

Hong Kong
We love moviesssssssss!, GC5JC7K
D2 / T1.5

As the name implies, this cache is located at an independent cinema in Hong Kong. Originally opened in 1996, this cinema is a cultural landmark, hosts various film festivals, and even has its own movie channel! Don’t forget to brush up on your film history, as you’ll need to answer a specific question to prise open the film canisters to reveal the cache.

D2.5 / T2

This unassuming stretch of Australian highway is home to the most Favorited Letterbox Down Under. An environmental cache, this Letterbox is made entirely of recycled materials and junk—remember that’s not trash, it’s a geocache…or in this case, a Letterbox!

Binz Pier is located on the Baltic Sea, and is the perfect location to send a postcard home. Good thing there’s a Letterbox there that will let you do just that!

The most Favorited Letterbox in North America is also a personal favorite of us here at Geocaching HQ. An integral part of the HQ GeoTour, cachers visiting HQ can stop here to send a quick postcard, complete a stop on the GeoTour, and take some Seattle themed pictures in front of the nearby mural.

Located 4650 m (15256 ft) above sea level, this cache is a must-grab if you are trekking to Machu Picchu. Featuring stunning scenery, including towering mountains and a crystal clear lake, you’ll never send a postcard from a prettier spot.
