Honestly,
Many children this age are ready to give up their afternoon naps, but need to be taught how to play quietly in their rooms by themselves. At one point my son only had his bed and his dresser in his room, the rest of the room was completely empty. As he learned how to behave during rest time he earned back some of the books and stuffed animals we had taken away. As soon as he destroyed a book or started playing really loud those items were put back into the treasure box.
We also had special toys just for nap time so he was excited to play quietly with them. But, the biggest trick with my son, I couldn't stand outside his door or even check on him, he had to learn how to sooth himself without my help or intervention. By standing in the hallway or checking on him every 15 minutes I was distracting him and providing the interaction he was looking for.
We started to get into a routine where he would cry louder and louder until I finally came and gave him the interaction he wanted, but what he really needed was a bit of a rest. So, as a mom I had to make the hard choice to tell him no, that he needed to play quietly and mommy was going to sleep. Then ignore any and all sounds coming from his room (unless he was hurt, of course). Eventually he got the idea. I was just very lucky my son was not a climber, otherwise I would have had a real problem on my hands!
Good luck!
