East Spanish Peak is a high mountain peak in the US state of Colorado. It is the lower of the two Spanish Peaks, two large igneous stocks which form an eastern outlier of the Culebra Range, a subrange of the Sangre de Cristo Mountains.
While the Spanish Peaks have the appearance of volcanic cones, they are actually stocks, remnants of an igneous batholith which formed underground around 25 million years ago. They are surrounded by radiating dikes, up to 14 miles (23 km) long, made of the same material.
The standard ascent route for East Spanish Peak ascends the west ridge of the peak from the saddle between it and West Spanish Peak. A trail ascends to the saddle from the north side of the peaks.
