What type of activity involves guiding participants around a farm and discussing its operations?

Educational tours specifically focus on providing visitors with insights into the workings of a farm through guided experiences. These tours allow participants to learn about various agricultural practices, crop cycles, livestock management, and other operational aspects related to the farm. The format typically involves a knowledgeable guide who explains the processes and answers questions, enriching the participants' understanding of farming.

Workshops usually involve hands-on activities or lessons focusing on specific skills or topics, rather than providing a comprehensive overview of farm operations. Field trips may pertain to educational outings to various locations but are not specifically centered on the farm's operating procedures. Farm markets primarily deal with the sale of agricultural products and do not encompass the educational aspect of guiding participants through a farm's operations. Thus, educational tours best encapsulate the activity described in the question.
