Best life experience

Either sleeping under the stars on a private tiny island, surrounded by the moon and the lightning in the sea, waking up at 6 am to climb a 200m+ rock on the island to see the sunshine. (The island was like 200m from other end to the other.) (at the night the water level rose to cover 90% of the island, only leaving the big rock/hill and our tent.)

Or climbing the Tai mountain for 10 hours during the night to see the sunrise in China.

Or driving in a Greek island for all day with the locals.
