Hello. Would you tell me which is best?

Suppose you are traveling in Kyoto. Someone asks you, "Sightseeing?". You will say,"Yes, ....."

This is our summer trip to Kyoto.

This is our trip to Kyoto for summer.

This is our trip to Kyoto in summer.

Do you have a better expression? If any, will you tell it to me?

Yes, we are visiting Kyoto this summer (a single or only occasional such journey)
Yes, this is our annual summer trip to Kyoto (you make this journey every summer)
Oh, this "our annual trip" is a very good expression! Thank you.
