Whilst in Koh Phangan in Thailand, after a few days of crazy adventures and activities, I had a few days with nothing planned. So a friend and I rented some scooters and just drove around the island - no plan, no direction, just driving. We came across some of the most amazing viewpoints and secluded beaches (which even had little wild piglets roaming around on them).
We ended the day just watching the sunset next to a waterfall we found with the most awesome rock pools at the bottom that we could take a dip in. It was so surreal and the spontaneity just made it a million times better; there was no time limit, no itinerary, and no cares. Best day of my life!
