There are museums, and then there are "living museums" that the kids (and mom and dad) will surely find interesting. El Rancho de las Golondrinas is such a place. See attractions like original colonial buildings on this site that date back to the early 18th century as well as other buildings that have been reconstructed to reflect the style of that time period. The buildings and other items presented here tell the fascinating story of the early settlement of New Mexico. The museum is closed from November through March.
Loretto Line Tour Company makes exploring Santa Fe more like an adventure than a difficult chore. The tour is an excellent way to learn more about the area as well as absorbing some detailed but highly interesting history in the process. You'll dig deep and go "beyond the plaza" to some of the city's most historically and culturally rich locations. Your guides will make seeing and learning about it all even more fun than you could imagine, and by the time your tour is done, you'll possess a level of knowledge about Santa Fe that will make you appreciate the city even more.
Getting out and enjoying the attractions of nature with the whole family is always fun, but it is even more enjoyable when you head out for your outdoor adventure to Santa Fe's Nambe Lake Falls. In addition to the amazing waterfalls, you can enjoy such fun activities as camping, fishing, rock climbing, and hiking. And if all those activities leave you more than a little hungry, there are plenty of excellent spots where the whole family can enjoy a picnic together before venturing out again.
