Point Pinole is a great place to visit on a sunny day any time of year. This easy loop gives you great views over a relatively flat trail, and you'll cross through some fascinating history — this was once the domain of dynamite factories making explosives for the mining and construction industries.
But there's still lots of diversity here. Here's what historical ecologist Robin Grossinger told Bay Nature for a 2007 article about East Bay shoreline parks: "Point Pinole is a microcosm. It's compressed–within 500 to 1,000 feet you can go from rolling grasslands to tidal marsh to beach to mudflat to Bay waters. You rarely see that intact nowadays–it's usually spread out over a mile or so, but here you can see it all."
