The 214-acre site, developed in conjunction with the 241 Toll Road, includes preserved and restored coastal scrub habitat surrounding Siphon Reservoir. The restored area was formerly a citrus orchard. Come prepared to walk along fire roads that cross the site and see the wildflowers that have bloomed following the Santiago Fire. A plant ecologist will discuss fire recovery and the resurgence of specific plants that follow fires in Southern California. This tour will also include information about the restoration techniques used to create sustainable habitat for the California gnatcatcher, a threatened songbird. This is a moderate hike.

This conservation area located near Coto de Caza was preserved as part of the construction of the 241 Toll Road. This hike gives participants a peek at an 1,182-acre area rich with coastal sage scrub, oak woodland, perennial grassland and natural drainage habitats. The natural history of the site, including geology, soils, plants, insects, birds and reptiles will be the focus of this hike. The tour, which includes some hills, will be led by a plant ecologist and an ornithologist.

This moderate six-mile hike begins in the Laguna Coast Wilderness Park and leads participants up through an oak woodland canyon, toward the 73 Toll Road. It continues through a wildlife undercrossing where participants can look for tracks and identify wildlife using the crossing. The hike will continue to a scenic point overlooking Shady Canyon, Laguna Canyon and beyond. The plant ecologist who oversees the Toll Road slopes will describe restoration techniques used to create sustainable habitat along the slopes for the California gnatcatcher, a threatened songbird. Come prepared to walk along moderately steep trails.

The 21-acre Bonita Creek restoration site is the main wildlife link from Upper Newport Bay to the San Joaquin Hills and was restored in association with the construction of the 73 Toll Road. This creek was restored from a narrow rip-rap lined ditch and underground culverts to a viable riparian habitat rich with wildlife. This easy hike will be primarily on a path located on top of the slopes that buffer the riparian area. The walk will include a path along San Diego Creek to a restored saltwater marsh. Bird watchers will see wetland, riparian, and coastal sage scrub bird species. The restoration hike will focus on plants and the methods used to restore the creek and riparian habitat.
