Adventure Treks


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!

Pacific Sunset

Adventure Treks for Adults: Sunset and Moonlight in Tennessee Valley!

Saturday, October 11th | 5:30 pm - 9:00 pm | Tennessee Valley Trailhead

Need a change of pace for your Saturday night? Dinner and a movie growing stale? Dancing shoes worn out? Then come out to Tennessee Valley with Tree Frog Treks for our first grown ups-only Adventure Trek!

It's an easy two mile hike out to the coast, and on the way our experienced naturalists will talk about the fascinating creatures that call Tennessee Valley home. We'll keep our eyes peeled for curious bobcats, circling hawks, slithering snakes and more!

After watching the sunset over the Pacific (hot cocoa will be served), we'll walk back under the light of the moon and listen for owls hooting, coyotes baying, and chorus frogs calling. It's an evening of adventure, education, and fun -- not your typical Saturday Night!

Ages 21 and over | $15 per person
