What Are Some Fun Things To Do In San Diego – Your Outdoor
You’ve seen the postcards: sunny beaches, the world-famous zoo, and a bustling downtown. But you know there’s more to a place than its most popular attractions. You’re looking for the trails, the quiet coves, and the wide-open spaces that don’t make it into the typical travel brochure. You’re asking what are some fun things to do in san diego, but you’re asking it like an explorer, not a tourist.
We hear you. Sifting through generic recommendations to find real, soul-stirring adventures can be a frustrating chore. The common problems often involve crowded spots that don’t deliver the nature connection you crave.
This guide promises to cut through that noise. We’re going to show you the San Diego that OutwardLab readers want to see—a place of rugged coastlines, challenging peaks, and starkly beautiful deserts. This is your blueprint for an adventure that builds skills and creates lasting memories.
In this comprehensive what are some fun things to do in san diego guide, we’ll cover the best coastal explorations beyond the main beaches, incredible mountain hikes just a short drive from the city, and the secrets of the vast Anza-Borrego desert. Let’s gear up and get outside.
Coastal Adventures Beyond the Crowded Beaches
San Diego’s 70 miles of coastline are legendary, but the real magic happens when you trade the flip-flops for a paddle or a good pair of hiking shoes. These activities get you up close with the powerful Pacific and its incredible ecosystems.
Kayaking La Jolla’s Seven Sea Caves
Paddling into the echoing chambers of the La Jolla sea caves is an unforgettable experience. Formed by relentless wave action, these sandstone grottos are home to sea lions, cormorants, and bright orange Garibaldi fish.
You can rent a sit-on-top kayak from several outfitters in La Jolla Shores. Always wear your PFD (Personal Flotation Device), like a comfortable NRS Chinook, even if you’re a strong swimmer. Pack your phone and keys in a reliable dry bag, such as one from Sea to Summit.
A pro tip: Check the tide charts before you go. The caves are most accessible during a lower tide. Be mindful of ocean swells, and if you’re a beginner, stick with a guided tour for safety and expert insight.
Tide Pooling at Cabrillo National Monument
When the tide recedes at the tip of the Point Loma peninsula, a hidden world is revealed. The rocky shoreline at Cabrillo National Monument teems with life, from scurrying crabs and sticky anemones to sea stars and tiny octopuses.
The key is timing. You need to visit during a low or negative tide for the best viewing. Wear sturdy water shoes with good grip, like Keens or Chacos, as the rocks are sharp and slippery. This is a perfect, low-impact activity that highlights the benefits of slowing down and observing nature closely.
Remember, this is a protected area. Practice eco-friendly what are some fun things to do in san diego principles here: look but don’t touch or move the animals, and never take anything from the tide pools. Step carefully to avoid crushing fragile creatures.
Hiking at Torrey Pines State Natural Reserve
For breathtaking coastal views and a glimpse of the rarest pine tree in the United States, head to Torrey Pines. This reserve offers a network of well-maintained trails that wind through sculpted sandstone cliffs high above the ocean.
The Guy Fleming Trail is a gentle, accessible loop with stunning overlooks, while the Beach Trail offers a steeper descent to the sand below. No matter which path you choose, carry at least one liter of water and wear sun protection. The Southern California sun is strong, even on overcast days.
What Are Some Fun Things to Do in San Diego for Mountain Lovers?
Many visitors are surprised to learn that San Diego County is incredibly mountainous. Just a short drive east, you can escape the coastal haze and find yourself among oak woodlands, pine forests, and granite peaks offering panoramic views.
Summiting Cowles Mountain for Sunrise
As the highest point within the City of San Diego, Cowles Mountain is a popular but rewarding hike. To beat the crowds and the heat, tackle it for sunrise. The 360-degree view of the waking city, distant mountains, and the ocean is worth the early alarm.
The main trail is a 3-mile round trip, but it’s a steady, rocky climb. Good hiking shoes with ankle support are recommended. The most crucial piece of gear for a dawn patrol hike is a reliable headlamp, like the Black Diamond Spot 400, to light your way on the ascent.
Exploring Cuyamaca Rancho State Park
An hour east of the city, Cuyamaca offers a true mountain escape. Hike to the 6,512-foot summit of Cuyamaca Peak or tackle the shorter but equally scenic Stonewall Peak trail for incredible views of the surrounding landscape.
The park is a testament to nature’s resilience, with vast areas recovering from wildfires. This offers a unique opportunity to study forest succession. You can camp at Paso Picacho or Green Valley campgrounds for a full weekend immersion. This is a great example of how to what are some fun things to do in san diego for more than just a day trip.
Bouldering in Mission Trails Regional Park
For those who prefer vertical challenges, the granite boulders scattered throughout Mission Trails Regional Park offer endless opportunities. Areas like the “Mad-Max Wall” and “The Ghetto” provide problems for climbers of all skill levels.
If you’re new to bouldering, go with an experienced friend. You’ll need specific gear: climbing shoes for grip, a chalk bag to keep your hands dry, and a crash pad for safety. It’s a fantastic way to build strength, problem-solving skills, and connect with a passionate outdoor community.
Discovering the Anza-Borrego Desert State Park
Welcome to the wild side of San Diego County. Anza-Borrego is California’s largest state park, a vast expanse of badlands, slot canyons, and oases. This is where you come for solitude, starry nights, and a profound sense of adventure.
Hiking The Slot Canyon
One of the park’s most popular features is “The Slot,” a narrow siltstone canyon that you can walk right through. Squeezing through the towering, water-sculpted walls is an experience unlike any other.
The trail is relatively easy, but you must be prepared for the desert environment. Never enter a slot canyon if there is rain in the forecast, even miles away, due to the extreme risk of flash floods. Carry more water than you think you need—a 3-liter hydration reservoir like a CamelBak is a good minimum.
Witnessing a Wildflower Superbloom
In years with ample winter rain, the desert floor can erupt in a breathtaking carpet of wildflowers. This seasonal event, usually occurring between late February and April, is a major draw. You can find bloom reports on the park’s website or by calling the visitor center.
This is a cornerstone of sustainable what are some fun things to do in san diego. To protect this fragile miracle, always stay on designated trails. Crushing the soil can damage seeds that may wait years for the right conditions to bloom again.
Stargazing and Off-Grid Camping
Anza-Borrego is an official International Dark Sky Park, making it one of the best places in Southern California for stargazing. On a moonless night, the Milky Way is so bright it looks like you could reach out and touch it.
The park allows for dispersed, or “open,” camping throughout most of its 600,000 acres. This is true self-reliant camping. You’ll need to pack in everything you need—including all your water—and pack out all your trash. A high-clearance 4×4 vehicle is recommended for accessing the more remote areas.

Preparation is the difference between a great memory and a bad situation. San Diego’s microclimates can be tricky, and being ready for anything is one of the key what are some fun things to do in san diego best practices.
The Layering System is Key
You can start a day in fog on the coast, drive through 80-degree sun inland, and end with a chilly evening in the mountains. Dress in layers: a moisture-wicking base layer, a fleece or insulated mid-layer, and a windproof/waterproof outer shell, like the lightweight Patagonia Houdini.
Hydration and Sun Protection are Non-Negotiable
Dehydration and sun exposure are the most common problems adventurers face here. Always carry a reusable water bottle or hydration pack and sip frequently. Wear a wide-brimmed hat, sunglasses, and apply sunscreen, even on cloudy days.
Navigating and Communication
Do not rely on your phone’s cell service in the mountains or desert. Download offline maps using an app like Gaia GPS or AllTrails Pro before you leave. For true peace of mind on solo trips or in remote areas, consider carrying a satellite messenger like the Garmin inReach Mini.
