Colton Point originally opened with only "limited facilities", but the success of the tourism campaign led to the park's expansion by the CCC. New facilities were added in 1938, and included buildings such as picnic pavilions, latrines, and a concession stand, as well as "stone cook stoves, tables, and developed trails and overlooks ... an amazing amount of work in one year". The CCC also built the road to the park and planted stands of larch, spruce and white pine for reforestation. On February 12, 1987, the entire park was listed in the National Register of Historic Places (NRHP), including "eight buildings and nine structures".
