I highly recommend this course to anyone looking to connect with nature and learn from passionate experts. Each speaker is knowledgeable, enthusiastic, and eager to share with students.
Tuleyome's CalNat course was a transformative experience for me. Not only did I gain a deeper understanding of the natural world, but I also formed lasting connections with beautiful landscapes in my backyard!
The hands-on field trips and learning opportunities from guided trips to self-guided adventures and intentional projects sparked joy and curiosity within me and others in the course.
The regionally specific presentations about flora and fauna of the Inner Coast Range and Sacramento Valley were specifically quite helpful in fostering discussion.
The instructors were excellent, knowledgeable and inspiring! The class was fun and engaging!
Thank you to the folks at Tuleyome for providing a supportive space for personal growth and development, for people from all walks of life.
