Description: San Diego's only lakeside resort nestled on the shore of Lake San Marcos. The Quails Inn Hotel at Lake San Marcos Resort offers rooms, suites, and cottages many with a view of the lake, mountains, and swimming pools. Dine in one of our restaurants or play golf on our 18 hole, par 72 championship golf course or maybe a lakeside picnic is just your speed. As a hotel partner to Legoland, the wild animal park, and the San Diego Zoo, we have created packages appealing to all ages and the adventuresome.
