Saturday, April 3rd, we decided to take the train down to Albuquerque so that we could check out the Zoo. A round-trip ticket costs $6 for students. Unfortunately, the earliest train leaves Santa Fe at 11:20am, so you get to Albuquerque at around 12:50pm. The last train leaves Albuquerque at 4:44pm, so that only leaves about 4 hours to spend in the city, unless you want to stay there all night. The Zoo takes about 20 minutes to walk to, and we decided to stop and get some food from Asian Noodle's and Bar on the main street in Albuquerque where you get off the train. The food was very good and reasonably priced.
The zoo's admission costs $7 for just the zoo, and then some additional charges for the aquarium or train rides around the zoo, but you can only get the package deal if you get there before noon (which I would recommend doing if you would like to be able to see everything in the zoo... so you might need to go there on a weekday so that there is an earlier train ride.)
