Between 15 July and 26 July 1904, Denver visited Galveston, Texas, where she was presented a gift of silver service from the people of Denver. She cruised in the Caribbean, investigating disturbances in Haiti, then returned to Philadelphia on 1 October. During the next two and a half years, she cruised the Atlantic Coast and in the Caribbean, joining in target practice and other exercises, and protecting American interests from political disturbance in the West Indies.[4] On 13 September 1906, a landing force consisting of six officers and 124 bluejackets and marines, under the command of Lt.

This landing force returned on board on 14 September 1906.[5] Crewmembers serving on Denver between 12 September and 2 October 1906 qualified for award of the Cuban Pacification Medal.[6]
The cruiser sailed from Tompkinsville, New York, on 18 May 1907 for duty with the Asiatic Fleet in the Philippines, sailing through the Mediterranean and Suez Canal to Cavite, where she arrived on 1 August. Denver visited ports in China, Manchuria, and Japan, and joined in the regular exercise schedule of the fleet until 1 January 1910, when she cleared Cavite for Mare Island Naval Shipyard.

On 19 July 1912, Assistant Secretary of the NavyBeekman Winthrop announced that on 30 July, Denver would depart Mare Island bound for the west coast of Mexico and its principal ports including Mazatlan and Acapulco before returning to Mare Island in what he termed "a friendly call."[7][8] However, because of worsening political turmoil in Nicaragua that threatened American lives and property there, Denver was instead ordered to proceed from Santa Cruz, California to Mare Island to replenish stores for a trip to San Diego, where she was due 10 August, and after that, on to Central America.[9] At San Diego, Denver's departure was delayed until 13 August due to engine repairs.[10]

Denver's arrival at Nicaragua was further delayed when she stopped on 17 August, to render assistance and attempted to tow off and later, refloat a merchant ship, S.S. Pleiades that had run aground off the coast of Mexico that day. Denver and her crew remained until 21 August; however, their efforts to dislodge the ship were unsuccessful. With the crew and passengers of Pleiades out of danger, Denver continued south to Nicaragua.[11]
For the next five years, Denver cruised the West Coast from San Francisco to the Panama Canal Zone, patrolling the coasts of Nicaragua and Mexico to investigate and prevent threats to the lives and property of Americans during political disturbances, carrying stores and mail, evacuating refugees, and continuing the schedule of exercises which kept her ready for action.[4] Crew members serving on Denver between 29 July and 14 November 1912 qualified for award of the First Nicaraguan Campaign Medal.[12]

Reed landed at Corinto, Nicaragua, for duty ashore between 27 August and 26 October 1912 to secure the railway line running from Corinto to Managua and then south to Granada on the north shore of Lake Nicaragua. One officer and 24 men were landed from Denver at San Juan del Sur on the southern end of the Nicaraguan isthmus from 30 August to 6 September 1912, and from 11 to 27 September 1912 to protect the cable station, custom house and American interests.[13][14][15]Denver remained at San Juan del Sur to relay wireless messages from the other navy ships to and from Washington[16] until departing on 30 September, for patrol duty.[17]
Denver departed Corinto on 26 October 1912 to return to Mare Island with stops at Mexican ports on her way back to California.[18][19] She was at Manzanillo, Mexico on 1 November[20] and San Diego on 9 December[21] where she remained through 20 December, conducting gunnery practice before returning to Mare Island.[22] In early 1913, Denver made an uneventful 3+1⁄2-month cruise in Mexican waters, during which time she made stops at Acapulco, Acajutla, San Salvador and Corinto, before arriving at San Diego on 3 May 1913.[23]
