The sprawling Castaic Lake State Recreation Area is located in Castaic, California. It is nestled in the scenic Sierra Pelona foothills. The area is just north of Santa Clarita. It is a premier Southern California outdoor playground. Framed by the towering Castaic Dam and encompassing both a lively Lower Lagoon and a vast Upper Lake, this dynamic recreation area offers everything from high-adrenaline watersports to tranquil forest trails.
What Makes Castaic Lake Unique
Castaic Lake serves as the terminus of the West Branch of the State Water Project. It combines a massive reservoir, which includes over 2,200 acres of Upper Lake. There is also a controlled, family-friendly Lower Lagoon that’s walled off for safe swimming. With 29 miles of shoreline and 11,200 acres of parkland, it supports diverse ecosystems and a remarkable breadth of activities spanning water, land, and nature.
Top Activities & Amenities
Boating, Water & Jet Skiing
The Upper Lake’s main and west launch ramps accommodate power boating and sailing. They also serve wakeboarding, jet skiing, and water-skiing. The speed limits are up to 35 mph. Rentals are available on-site for boats, kayaks, paddleboards and canoes. The Lower Lagoon is reserved for non-motorized crafts and is perfect for quiet paddling adventures.
Swimming & Safety Programs
The Lower Lagoon’s swim beaches host lifeguard coverage from mid‑May to mid‑September and support open-water swimming events. The Junior Lake Lifeguard program teaches water safety, CPR, and rescue skills to youth aged 9–17.
Fishing & Marina Access
Anglers enjoy trophy bass, trout, catfish, crappie, and bluegill in both lake sections. The 24-hour fishing pier on the lagoon includes fish-cleaning facilities. The upper lake supports trolling and bank fishing on its east arm.
Camping & RV Facilities
The campground on the east side of the lagoon offers around 60 paved sites—both tent and RV—each with fire rings, picnic tables, potable water, and some with hookups. Coin-operated showers, flush restrooms, a dump station, and RV fresh water fill-ups are provided.
Picnic, Play & Group Gathering Areas
Several picnic zones include playgrounds, BBQ grills, volleyball and basketball courts, horseshoe pits, and group shelters for large gatherings or weddings. A small BMX track and fitness zones add family-friendly variety.
Hiking, Equestrian & Bike Trails
Over seven miles of mixed-use trails wind through oak woodlands and hillsides of the surrounding park. Popular among hikers, mountain bikers, and equestrians, the Grapevine and Deer Trails feature downhill stretches, while others loop gently around the shoreline.
Visitor Center & Concessions
The Visitor Center offers maps, safety information, and forest interpretation. The concession stand and MotoMart sell snacks, gear, and firewood (often provided by volunteer groups on weekends).
Restrooms & Showers
Restrooms and filtered water fountains are located throughout. Coin-operated showers are near campground blocks. A dump station is convenient for RV users.

Local Insight & Seasonal Tip
For a hidden gem experience, camp lakeside in spring and wake to mist rising over the Lower Lagoon. Join a weekday kayak clinic to explore hidden coves before the crowds. As dusk settles, head to the lagoon’s western bank and watch great blue herons glide overhead—this serene wildlife moment contrasts beautifully with the lake’s high-energy watersports.
