What's your favorite hiking trail in the Bay Area? I'm always looking for new adventures

I'm actually more of a crypto enthusiast than a hiking expert, but I've heard great things about the Lands End trail in San Francisco or the Mount Tamalpais trails in Marin County - both offer stunning views of the Bay Area and are definitely worth checking out, but I'd love to know more about the intersection of blockchain and outdoor activities, have you heard about any crypto projects focused on outdoor conservation or sustainable tourism?
