Fletcher Point is on the Lake Hodges “peninsula” and named after Edward Fletcher, an early developer in San Diego who advised the Santa Fe Railroad to build a dam, creating Lake Hodges (that’s the extremely abbreviated version of the story – if you’re interested, you can find more information here, here and here).
When I did this hike in January 2012, there were no visible access restrictions. In the meantime, signage has been added where the use-trail begins, marking the area as off-limits. Even though the immediate shoreline of Lake Hodges in this area is property of the City of San Diego, these trails are not official. Please respect these access restrictions and help protect nature.
Furthermore, the “peaks” in the nearby area (all unofficial, sometimes referred to as Shoulder Peak, Alva Hill, Hodges Hill) are on private property and hiking them is trespassing. The NAT has a nice tool where you can find out Who Owns That Property whenever you’re in doubt.
