  • TERRAIN: A mostly even path to reach Annie’s Canyon Trail. However, watch out for tree roots that people could trip on. Note some soil erosion on the descending trail from Annie’s Canyon viewpoint and some stairs.

    The slot canyon’s vertical, narrow areas could aggravate claustrophobia. On the slot canyon path, there are ladder-style stairs, and on the switchback approach, you encounter wooden-plank stairs. At certain points, you need to scramble (aka use your hands + feet to propel yourself up).

See a true natural wonder – right in your county’s backyard –

The sandstone canyon walls display breathtaking shapes that are a don’t-miss gift from mother nature. What happens when thousands of years of coastal rains fall? In this particular case, those rains yielded a unique slot canyon – and what we think is one of the best hikes in San Diego – for us to appreciate and enjoy.

In this slot canyon, you get up-close and personal with San Diego’s unique geology. On either side of you, you can observe these naturally eroding canyon walls. Don’t forget your camera – and a spirit of adventure! (Tag your Instagram photos with #anniescanyontrail)

What to Expect

  1. Starting with a slight decline with spaced-out steps, the Rios Trail brings you through the coastal sage scrub.
  2. Green signs will direct you towards Annie’s Canyon Trail as you continue to follow the Rios Trail.
  3. Benches along the trail provide resting places with fantastic views of the estuary channels throughout the lagoon.
  4. As you approach Annie’s Canyon Trail, there are 2 options: (1) You can go through the canyon, which requires some strenuous activity, or (2) you can hike up the switchback portion. Note the switchback’s moderate incline (rising ~300 feet in approx. a quarter-mile) and erosion-control steps.
  1. If you decide to go through the canyon, keep in mind that the path is one-way, so you must take the switchback path down. As you progress through the canyon, the path narrows. However, you can use available footholds – and ladder-like stairs – to maneuver to the top of the canyon.
  2. Whether you go through the canyon or up the switchbacks, the top of Annie’s Canyon Trail offers views of the Pacific Ocean and wetlands.
  3. Once you’re ready for the return journey, go down to the Rios Trail, and retrace your steps. You arrive at the trailhead.
