What are the must‑see outdoor activities for newcomers?

San Diego’s coastline offers surfing, paddle‑boarding, and kayaking at numerous beaches that are less crowded than the main tourist strips. Inland, the city is surrounded by coastal foothills and state parks with trails ranging from easy walks to challenging hikes with ocean views. Popular activities include exploring tide pools, biking along scenic coastal routes, and visiting lesser‑known nature reserves that provide wildlife viewing. For up‑to‑date trail conditions and water‑sport rentals, check the city parks department’s website and regional outdoor recreation guides.
