Sometimes guerilla marketing can feel forced or over-the-top. But over the past year, tourist attractions have been engaging passersby in ways that capture the curiosity and inner child that lie within all of us. These three – interestingly, all outside of the U.S. – really stand out as campaigns that are not only clever, but connect with the target audience in meaningful and emotional ways.

This ad, part of a campaign from the V & A Museum of Childhood in London, uses vinyl “street art” to play off the outside environment. The message, “See the world through a child’s eyes,” appeals to adults, while the vibrant visuals would catch the eye and imagination of any child who walked past.

This past summer, Splashdown Waterpark in Vancouver planted free tickets at the bottoms of huge barrels of water and behind active sprinklers with its “Get wet for free” campaign, giving potential visitors a taste of the cooling off they’d experience at the actual park.

Almost exactly a year ago, the Zoological Park of Paris opened its doors. To generate excitement about the coming attraction, they placed giant open animal crates amongst famous city sites, creating the illusion that the animals had escaped and might be lurking about behind the Eiffel Tower or wading in the Saint Sulpice Fountain.
