Lower Otay Reservoir is a useful outdoor escape on Chula Vista's inland edge, with fishing, boating, and dry hills that feel far from the bayfront. It shows a different side of South Bay geography: reservoirs, chaparral, and open sky rather than beaches and suburbs.
It is best for anglers, walkers, and travellers who want a quiet morning outside. Check reservoir rules before going, since boating days, permits, and access points can be specific.
