Hi! That's great news, congratulations on getting permission to go on the day trip! Our teacher did mention that we could do some walking or try some horse riding during the trip. Personally, I would prefer to do some walking because it allows me to explore the countryside at my own pace and take in the scenery. Walking is also a great form of exercise and I enjoy being outdoors and getting some fresh air. However, if someone is interested in trying something new and adventurous, horse riding could be a great option as well. Ultimately, it depends on each individual's interests and preferences. As for what to bring, I would recommend comfortable shoes, sunscreen, a hat, and a water bottle to stay hydrated.
