After the bus arrived at Larissa Station, it wasn't hard to find the bus pictured. The guide was kind and cheerfully explained a lot of information, and I was able to learn a lot. You can choose to enter the three monasteries by paying an admission fee, or not, it's optional. I recommend visiting the last monastery, St. Stephen's. It was nice that we stopped at several spots to take pictures along the way. Lunch was delicious, and water was provided after arriving in Meteora, so it's a good idea to bring water to drink before that.
