Stop by Portside Coffee and Gelato for cozy caffeinated treat, and walk the 2.3 mile loop around San Diego’s scenic Shelter Island! With stunning views of Downtown San Diego and the San Diego Harbor, this trail is great for those who want to walk, run, or road bike. Perfect for a sunny San Diego December day or even a rainy drizzly one. Always ethereal and stunning! You can even spot seals on a good day 🙂
