What is the Challenge? 

The Trail to Bay Challenge is free.

Living Coast cleanups also take place at various locations throughout the year. You will join other families and volunteers passionate about making an impact in their community and help clean up areas near the bay affected by trash and debris. You will also learn ways to conserve our planet, recycle, and compost by making small changes in your daily lives. Attend three hikes and one cleanup to complete the challenge.

Groups that complete the Trail to Bay Challenge will get a family four-pack valued at $80 (one per household) and a Sustainability Hiking Pack.

The Living Coast is proud to partner with the City of Chula Vista on the Trail to Bay Challenge.

How to Prepare

Participants are encouraged to wear comfortable walking shoes, hat, sunglasses, and sunscreen. It is also recommended to bring enough water for the hike, keeping in mind the time of year and temperatures. Dehydration can set in quickly, and it is recommended to bring half a liter of water per mile. Don’t forget to dress for the weather, bring a jacket and dress in layers, if necessary.


Although most sites allow leashed pets, we ask that you keep your pets at home to prevent any disruption to wildlife. Please do not litter or smoke on the trails. Guests of all ages are welcome, but an adult must be present for participants under the age of 18. Please limit phone conversations while on the hike as they are a distraction to your fellow hikers. We ask that these hikes be reserved for families and friends, large groups of 15 or more should inquire about a private hike option by contacting the Living Coast Education Department,


All locations have free parking options, but spots may be limited (Otay Lakes County Park has both paid and free parking). It is suggested to plan ahead and arrive early. All hikes will have a designated location for the group to meet along with a large canopy for identification located nearby the parking lot.


Families and friends are encouraged to join the Living Coast Discovery Center for clean-up events once per month. Locations will vary in and throughout Chula Vista. These opportunities will enable citizens to help make a difference in their community. As the host, the Living Coast will provide all necessary tools for the cleanups. Please dress appropriately. Prior to each cleanup, it is recommended you contact the Living Coast to confirm your spot and to receive important details and instructions. If you plan to complete the Trail to Bay Challenge you are required to participate in one clean up event. More information about upcoming cleanups and how to make a reservation can be found here.
