The Museum lies on the original 8.65-acre homestead owned by Chief Ouray and his wife, Chipeta. Migrating from the mountains in the summer to river valleys in the winter, the Utes used the abundant plants and animals of the Uncompahgre River valley for food, clothing, and shelter. Built in 1956 and expanded in 1998, the museum offers one of the most complete collections of the Ute people. The grounds include the Chief Ouray Memorial Park, Chipeta's Crypt, and a native plants garden. Recently renovated and expanded, the museum now includes the Montrose Visitor Information Center, gallery space, classrooms, and a museum store. The museum complex includes shady picnic areas, walking paths, and a memorial to the Spanish conquistadors who traveled through the area in 1776.

San Pasqual Battlefield State Historic Park honors the soldiers who fought in the battle between the U.S. and Californio forces on December 6, 1846 in the midst of the Mexican-American War. Generals Stephen Kearny and Andres Pico both claimed victory. The battle was only one of the military encounters in California in the war, but it proved to be the bloodiest and most controversial as to the outcome. The park has been set aside, not as a monument to war, but as a reminder of the human ideals, actions, and passions that can drive nations to bloodshed.

The park offers exhibits; tours; and occasional recreational and educational events, including living history events.

Fort Ross was a thriving Russian-American Company settlement from 1812 to 1841. This commercial company chartered by Russia's tsarist government controlled all Russian exploration, trade, and settlement in the North Pacific, and established permanent settlements in Alaska and California. Fort Ross was the southernmost settlement in the Russian colonization of the North American continent, and was established as an agricultural base to supply Alaska. Fort Ross was a successfully functioning multicultural settlement for some 30 years. Settlers included Russians, Native Alaskans and Californians, and Creoles (individuals of mixed Russian and native ancestry.) Along with the chapel, the structure of most historical interest at Fort Ross is the Rotchev House, an existing building renovated about 1836 for Alexander Rotchev, the last manager of Ross. It is the only surviving structure. Several other buildings have been reconstructed: the first Russian Orthodox chapel south of Alaska; the stockade; and four other buildings called the Kuskov House, the Officials Barracks, and two corner blockhouses.

The park offers exhibits, tours, educational programs, research library access, and occasional recreational and educational events.

The Watts Towers are a complex set of 17 separate sculptural pieces built on a residential lot in the community of Watts. Two of the towers rise to a height of nearly 100 feet. The sculptures are constructed from steel pipes and rods, wrapped with wire mesh; coated with mortar; and embedded with pieces of porcelain, tile, and glass. Using simple hand tools and cast off materials (broken glass, sea shells, generic pottery, and ceramic tile) Italian immigrant Simon Rodia spent 30 years (1921 to 1955) building a tribute to his adopted country and a monument to the spirit of individuals who make their dreams tangible. The Watts Towers are one of only nine works of folk art listed on the National Register of Historic Places. The site is one of only four US National Historic Landmarks in the city of Los Angeles. The Los Angeles City Cultural Affairs Department, through the Watts Towers Arts Center, provides diverse cultural enrichment programming through tours, lectures, changing exhibits, and studio workshops for both teachers and schoolchildren. Each year, thousands of people are attracted to the Towers' site for the Simon Rodia Watts Towers Jazz Festival and the Watt Towers Day of the Drum Festival.

The park offers exhibits, tours, lectures, workshops, and educational and recreational events.
