Santo Tomás is a populated place in the municipality of Caborca in Sonora, Mexico.
Bob developed the land as a cattle ranch but died in 1969, and Paulina maintained the cattle thereafter, but by 1971 relinquished those plans and began to develop a tourist destination and the site known today as Las Dunas de Santo Tomas.
[1] In 1996, Paulina and Bob's children decided to revive the tourism industry and built a partnership with a Mexican landholding corporation to establish Las Dunas De Santo Tomas.
[2] The city is a "free zone", meaning visitors from the US are welcome to enter without obtaining a visa.
[3] This makes Santo Tomás popular among Arizona, California and Nevada locals.
