When I go on a hike, I want to know there is something worthwhile at the end of the line.  Well, the hike along Annie's Canyon Trail in Solana Beach provides that and so much more.  Not only is there an amazing view of the ocean when you make it to the top, there are great views along the way.  Plan for about 40-minutes.  The entrance is off the Rios Avenue Trailhead.  This is a residential neighborhood and the trailhead begins at the end of the cut-de-sac.  As you start out you will overlook the San Elijo Lagoon, where they are currently performing environmental mitigation.  At the beginning, the trail is fairly flat, with only a minor incline. As you continue you will reach a fork in the road.  To the left you can take the moderate hike up to the viewpoint.  If you are going with people who are scared of heights or are not that flexible - I would recommend they take this route.  However, you are really missing out if you don't take the trail to the right - the more strenuous route.  However, it's really not difficult.  Just narrow.  And expect to do a little climbing. Once you start this way, there is no turning back since it is so narrow.  It's a one way loop to the top.  Here you'll see naturally eroding sandstone walls that will quickly surround you.  You can take little detours here and there and you may choose to climb some of the walls and enter some caves.  The maritime terraces look like large staircases that are flat on top. After you make your way through a few turns you will see a ladder staircase that will take you to the top.  From here you will see a panoramic view of north San Diego County to the east, the San Elijo Lagoon to the north, and the Pacific Ocean to the west.  You can look back behind you and see the natural beauty of the mushroom caves.  As you make your way down, you'll take the easy route.  There is a separate trail that can take you closer to the lagoon if you so choose.
