Tlalpan and Pedregal is a district of Mexico City.
Tlalpan  comprises several small towns south of Mexico City, including Tlalpan itself, Chicalcoyotl, San Pedro Martir, San Andres Totoltepec, Xicalco and San Miguel Ajusco. All of these towns eventually got merged into the urban sprawl and became what is today known as a "Delegacion" Tlalpan (borough or municipality) of the Federal District. It is the largest borough in Mexico City and borders with the State of Morelos. It is also home to the Ajusco volcanic mountains with the highest peak measuring 3,937 meters above the sea level.
In terms of foreign tourism, Downtown Tlalpan is a barely known place, which could make it a highlight if you visit it. Overall it is a quiet and safe place, with Colonial architecture, cobblestone streets and lots of trees.
The easiest way to reach the Centro Historico of Tlalpan is using an RTP bus , through Tlalpan Avenue or Insurgentes Sur avenues. The bus should have a sign that reads "San Fernando". Ask the driver you want to go "Tlalpan Centro". As in many other places in Mexico, the area lacks of traffic signs, so it is better to ask people for directions. There are also RTP buses that reach some of the old towns, these buses run along Insurgentes Sur, which later becomes the Federal (Libre) Highway to Cuernavaca.
The Centro Historico of Tlalpan comprises an area of maybe 6 x 6 blocks, which can be done by foot. If you plan to visit the other towns a Taxi or a Car will be necessary. Ask for a map at the Tourist Booth in the Zocalo (main square)
