Sunfan, Here are a couple more suggestions based on your reported interests. Check out the hikes and camping in the bisti badlands near Farmington. Its a great stop on the way through. There are several hiking trails in the Cibola National forest and Sandia mountains just outside Albuquerque that may be buried in snow in April, but may be not. If caving is an interest, check out Sandia cave. Its a nice hike, with the option for spelunking at the destination. Also the la Luz trail down from the top of the crest after riding the tram to the top. There are short hikes through the petroglyph monument on the west side of Abq.
