See 🚵 Tour komoot.de/tour/9817832 for highlighted segments and labeled photos

Note that on almost every tour Gopher snakes have crossed the trails in front of my bike. They often are not moving very fast so be careful not to roll over them accidentally with a mountain bike, particularly when shooting down the sweet descents of the fireroads and trails in the area.
NOT Dangerous (Non-poisonous)
Gopher Snakes do not have venom that is dangerous to most humans.

Gopher Snakes are one of the most commonly seen snakes in California. Primarily active during the day, they are also active after sundown on hot days. They are often observed crawling across trails and roads, especially in the morning and evenings when daytime temperatures are high. They are frequently seen around human dwellings, including suburban backyards, attracted to the rodents which thrive in such areas. Unfortunately, this harmless and beneficial species is very often killed out of fear that it is dangerous or that it is a rattlesnake. Take a look at some of the links and information here to help you learn how to know if a snake is a rattlesnake or a gopher snake.
