Loch Lomond Reservoir, a 175-acre lake in the Santa Cruz Mountains, offers flatwater paddling surrounded by redwood-covered hills. The lake serves as a drinking water source for Santa Cruz, which leads to specific restrictions for paddlers. Personal watercraft are not permitted unless stored on-site through the boat storage program. Instead, the recreation area offers rentals including rowboats, pedal boats, and "Nucanoes" available on a first-come, first-served basis.

The lake features several distinct paddling destinations, including Claire Innis Island with picnic facilities, and various quiet coves along the shoreline. The northern end of the reservoir offers more secluded paddling opportunities, with the possibility to explore up the feeder stream until water depth becomes too shallow. Wildlife viewing opportunities include waterfowl such as coots, mergansers, grebes, and occasional osprey hunting overhead.

Operating hours vary seasonally, with the facility open March through early October. The recreation area is closed every Wednesday for maintenance. Water temperature averages around 50°F (10°C), making appropriate clothing essential. Swimming is strictly prohibited to protect drinking water quality.

Rental rates start at $30 for the first two hours for human-powered boats. All boats must be off the water one hour before park closing time. The facility provides a boat ramp, parking, restrooms, and a park store with refreshments. A vehicle entrance fee applies.

Important regulations include mandatory inspection for aquatic invasive species, particularly Eurasian mussels. Dogs are allowed in the recreation area on leash but are not permitted on boats. The lake's smooth waters make it particularly suitable for novice paddlers, though wind conditions can vary throughout the day.

For paddlers interested in fishing, the lake is stocked with multiple species including rainbow trout, bluegill, largemouth bass, and channel catfish, though fishing is prohibited within 100 feet of dock structures.
