John Dunn Bridge is located in Arroyo Hondo in north-central New Mexico.

Recreational opportunities on the rivers include fishing, kayaking, and whitewater rafting.

[3] In or after 1893 John Dunn bought a bridge that crossed the Rio Grande and established a business taking passengers and freight from the Denver and Rio Grande Railroad at Tres Piedras to Taos.

[9] Kayaking and whitewater rafting are popular recreation activities on Rio Grande, particularly for experienced rafters.

[3][10] Black Rock Hot Springs are located off a dirt road on the western side of the Rio Grande after crossing the bridge.
