In the whole National Mall there are rangers on duty, who are responsible for law and order. Additionally, they are great tour leaders around the park, and the Park does not charge for their services.
They are available for answering your questions from 9:30 AM to 11:30 PM, and they are leading organized groups on tours around the park from 10 AM to 11 PM.
The programs consists of happenings, scheduled in advance, so if you want to take a tour around the Park, or listen about a particular monument, you may check out a calendar and see in what time which events takes place.
Those events have an educative character, the rangers have a role of a tourist guide, and they will talk for a while about some memorial or a historical event, in a general way.
Even if you are very familiar with the historical events and memorials in the National Mall, there is a great chance that you will hear some details you didn’t know beforehand, so it is worth to tag along with a ranger. And of course, it is better than just storm into the Park, take a thousand pictures, tell yourself that you’ve “seen it all”, and run to another place. Doing it that way, you won’t get a sense of the great essence of the American society captured in this park, and you won’t learn anything new, which is a shame.
Apart from regular touring the particular memorials, from time to time there are some special events which are worth attending.
Talking about Lincoln Memorial in particular, there is one event which takes place on March 3. From 2 PM to 4 PM, you can meet and talk with the Park “Triangle woman”, the sculptor behind Daniel Chester French, who designed Lincoln Memorial murals, Vietnam complex, and the wall in the Korean Memorial. This is a unique opportunity and if you interested in National Mall and Lincoln Memorial, you should not pass it.
From time to time, there are events designed especially for children, so if you child is not at school at that moment and the school itself doesn’t organize a tour around the Park, you could take them yourself to the Mall, when rangers can be found working on those specialized events. It is educational and useful, and kids will get a chance to play a few quizzes with a ranger, and get a junior ranger badge, or some similar reward.
