Present perfect tense - Talking about an action in the past :
- But the time is neither unimportant nor not mentioned.
- Example : I have gone to Japan before (we do not know when from the sentence)
-
- But the action still has influence now.
- Example : It has been raining heavily this morning so all the roads are still wet. – Meaning : although the rain stops, the roads are still wet.
-
- But the action still has not finished now.
- Example : I has been raining heavily since this morning (still raining now)
-
- Talk about an action that you expect to happen but it finally did not happen.
- Example : John has not come. (But you expect that he would come).
So, for your sentence, you can look at the above definition of present perfect tense and see whether your sentence belongs to anyone of the examples.
The answer is no. Therefore, you just need to use simple past tense :
This summer, although I did not do many things, I experienced many different kinds of things.
You do not need to use past perfect tense “had experienced” because you do not have 2 actions happened in the past and you need to tell us which one comes first.
