Santa Fe and its surroundings offer many opportunities for discovery, especially for those who wish to go beyond the immediate tourist areas. Sunsets are striking with colors which often appear surreal. Adobe buildings can be found that are centuries old. The Santa Fe River has brought life to this dry land for millennia. The high altitude sub-desertic environment is challenging for all vegetation. Each year, each season, even each day offers new opportunities to discover this ever-changing natural environment.
