If you like water sports, Snug Harbor Marina(Tamarack exit, Agua Hedionda Lagoon, (760) 434-3089) is a fun place to rent water-skiing boats, wave runners, canoes and kayaks. An unusual, gentle way to see beautiful Carlsbad is from the open cockpit of Biplane & Air Combat Adventures vintage aeroplanes. Thrill seekers can try their aerial dogfights –you’ll do most of the flying, but no license is required. Call 1-800-SKY-LOOP (1-800-759-5667) for reservations. Located at McClellan-Palomar Airport, three miles east of I-5 on Palomar Airport Road.
