At the heart of Castro Valley sits Lake Chabot, a 315-acre drinking-water reservoir surrounded by miles of parklands and walking trails. At the marina, Lake Chabot Fishing Outfitters provides a complete assortment of bait and tackle, along with rod and reel rentals, boat rentals, and a café stocked with breakfast and lunch. Depending on the season, anglers can try different fishing methods to track down their desired targets. In the fall through the spring, spoon and fly fishers often reel in hungry trout, and summertime anglers are often successful with catfish, crappies, bluegill, and largemouth bass.
At San Mateo and Alameda beaches, a look over the watery horizon often shows dotted figures atop surfboards taming the wind and waves. Boardsports' team of certified instructors schools these adventurous participants in kiteboarding, windsurfing, and standup paddleboarding during lessons that leave both beginner and intermediate participants ready for relays with dolphins. Its fully stocked retail shop also provides gear, equipment, and rentals of surfboards, wetsuits, and other supplies to make watertop experiences fun, safe, and stylish.
The Headwaters owners Dan and Ashlie Arbuckle strive to make aquatic exploration accessible by providing patrons with high-quality equipment, as well as moral support from their canine companion, Henna. The shop rents paddleboards and kayaks to paddlers intent on exploring the Mokelumne River and also organizes guided trips, exhibitions, and private or small group classes for newbies. In addition, fishing kayak packages rent out rod holders, fish finders, and scripts for tall tales about "the one that got away."
The owners of 7Star Rental wield more than 20 years of boating experience to equip ocean and lake adventurers of all levels for an active day on the water. Knowledgeable staffers can harness equipment such as wakeboards and inner tubes to all-fiberglass Tigé and Centurion-brand boats, or loan out a fishing vessel with plenty of storage space for bait and tackle. Events such as fishing trips and wakeboarding lessons help watersports newbies get their feet wet. In addition, Sea-Doos carry wave wranglers through California's many lakes, delta waterways, and Guinness World Record–breaking goldfish bowls.
Underneath the sky-blue rafters of Rockzilla's spacious indoor gym, a veritable mountain range of multicolored walls challenges climbers of all experience levels. Sheer-faced cliffs challenge the top-roping and lead-climbing techniques of both beginners and experts, and a mushroom-shaped structure builds skills in bouldering and reveals the fossil record of ancient screws and bolts. The mat-lined floor, harnesses, and dedication to belaying skills ensure every visitor's comfort and safety. In addition to hosting hangouts, parties, and team-building exercises onsite, Rockzilla crashes entire tectonic plates into customers' backyards, forming portable climbing walls available for rent.
Armed with gear from City Kayak, guests paddle past scenic San Francisco sites such as Alcatraz, the Golden Gate Bridge, and South Beach Harbor during guided or unguided treks. Visitors can navigate their way beneath the Lefty O'Doul drawbridge and catch home-run hits soaring out of the baseball stadium and into McCovey Cove, or advanced paddlers can traverse strong winds and tidal currents en route to Treasure Island. City Kayak also schedules classes, which teach students basic sea-kayaking skills, self-rescue techniques, and how to eskimo roll, an escape maneuver that one could use to avoid the songs of tone-deaf penguins. City Kayak rents out gear such as wetsuits and booties and also sells a collection of kayaks, paddles, and accessories to equip paddlers for future travels.
