Volunteer: Trail Maintenance @ Pence Park

Where You'll Be:

Pence Park is a beautiful, quiet respite just thirty minutes from Denver. Pence Park's wide variety of trails has become a popular destination for hikers and bikers along the Front Range. Mountain bikers flock from miles around to ride from Lair O' the Bear to Pence Park, a scenic 13 miles. Pence Park's unique array of wildlife includes bald eagles, Mexican spotted owls, the Preble's jumping mouse, and the Townsend's big-eared bat.

What You'll Do:

Volunteers will help with much-needed trail maintenance at the park, just a short trip from the Denver metro area. Tasks may include clearing the trail corridor by trimming overgrown vegetation to keep paths open and safe, maintaining drainage by removing debris and improving water flow to prevent erosion, and repairing the tread to smooth and reinforce the trail surface for a safer and more durable path. This is a great opportunity for new volunteers and anyone interested in learning more about trail restoration while enjoying a beautiful outdoor setting.

Why It Matters:

Trail maintenance matters from an ecological and environmental standpoint because it ensures a safe and sustainable route for people to use, which keeps the surrounding habitat safe and minimizes the human impacts on flora and fauna, especially in high-use areas like Pence Park.

Eligibility Requirements: Ages 16+

Project Difficulty:

This project is considered moderate; please check our difficulty rating criteria here for more details.

Physical Considerations:

You can expect to bend down, pick up objects, move rocks, carry tools, swing heavy tools, dig, and stretch.

Access Factors: 

Vehicle Access: No vehicle restrictions – 2WD accessible  Other Notes: Cell service may be spotty in this area.

Volunteer: Cascade Falls Park Trail Maintenance @ Ouray

Where You’ll Be:  

Known as the "Switzerland of America" and the "Outdoor Recreation Capital of Colorado," Ouray is a breathtaking destination nestled in the heart of the San Juan Mountains. This unique volunteer opportunity not only allows you to give back but also offers a chance to explore one of Colorado’s most stunning landscapes.

As a special perk, volunteers will receive free passes to Ouray’s famous hot springs—so don’t forget to pack a swimsuit! We’ll be camping at Rotary Park, a beautiful city park that is normally closed to overnight stays, making this a rare and special experience. For those who enjoy climbing, the park features excellent bolted routes, so feel free to bring your gear.

For those who want to extend their adventure, camping will also be available Sunday night, providing a great opportunity to relax and avoid a long drive home after the workday.

What You’ll Do:

The goal of this trail maintenance project is to improve two sections of trail that connect the Perimeter Trail to the base of Cascade Falls. One section on the south side of Cascade Creek has become overly wide, leading to unnecessary trampling of the creekside habitat and unstable footing.

To address this, volunteers will help define a clear, single pathway by incorporating natural landscape features to guide hikers. Work will include installing rock steps, building small retaining walls for stability, and improving the trail surface with native or imported stone. Additionally, we’ll create level areas where visitors can safely gather to enjoy the falls without causing further erosion.

Breakfast and lunch are provided on Saturday and Sunday, along with dinner on Saturday. Bring your own dinner for Friday night and enough snacks for the weekend. Free campsites are available on Friday and Saturday nights, and we recommend arriving at base camp before 8 pm on Friday.

Support This Project as a Crew Chef Helper!
We provide full meals on our overnight projects to ensure volunteers are well-fed and ready for a day of volunteering — and we could use your help to make it happen!
