About Nature Trip

Nature Trip celebrates 15 years!            

Nature Trip has been taking people out to experience the wild side of California and beyond since early 2004. During that time we’ve led hundreds of day tours and field trips, taught dozens of classes, presented presentations and performed thousands of hours of wildlife research and education – and it has all been great fun!

Hope you can join us for more of that in our near future!
