Family Adventure Trek: Tarantulas of Mt. Diablo!

Saturday, September 13th | 3:00 pm - 7:30 pm | Mount Diablo State Park

Every autumn, Mount Diablo becomes of the scene of an extraordinary migration: male tarantulas slowly make their way over roads and trails in search of mates!

Our Family Adventure Treks return on September 13th, so join us as we go on a beautiful sunset hike and road cruise in search of our eight-legged friends and anything else we can find! Last fall we met a praying mantis, watched a red-tailed hawk hunt, and found a tarantula! It's a once-a-year experience you don't want to miss out on! Space is limited.

Recommended for adventurers age 7 and up. | Children under age 13 must be accompanied by a paying adult | $25 per person

We will be driving two TFT vans from our office in San Francisco to Mount Diablo State Park. The best way to find the tarantulas after the hike will be on the roads, so everyone coming on the trek must be in our vans when we enter the park. You can either meet us at our office or in Walnut Creek. Please email Tony at if you have any questions or concerns!
