Special Interest travel is often referred to as SMERF (Social, Military, Educational, Religious, Fraternal) travel. Either way, it is about group travel, organized around specific interests or issues. Mexico has lots to offer for groups of this sort. For example, there are important pilgrimage sites in Mexico, none more important than the Basilica to the Virgin of Guadalupe. And, for birders, archaeology buffs, soccer or baseball enthusiasts, paragliders or geologists, Mexico is an exciting place to visit. For example, Mexico´s rich educational offering has made it a favorite destination for Elderhostel trips.
