Boat Ramps
South Shores Park has a boat ramp and RV dump, open 4 a.m. to 2 a.m. Boaters may park up to 72 hours. There is no overnight camping, and glass and alcohol are not allowed.
Fishing
The state free pier list names the Mission Bay Jetty North, where a license is needed for the adjacent rock wall touching land. See Pier Fishing Rules.
What We Could Not Verify
- Current City fishing rules for Mission Bay are not confirmed. An old 1994 master plan appendix, seen only in search results, said fishing is allowed in all areas except swimming areas, the watercraft area and bridges. Do not rely on it.
- De Anza Cove boat ramp and the El Carmel Point kayak launch appear only in search results and are not confirmed.
- Accessibility details and Bonita Cove-specific features are not confirmed.
- Smoking is not covered on the Mission Bay page; see the City-wide rule on Beach Rules.
