Twilight on the Trails

We have moved the event date from Saturday, June 13th, to Saturday, Sept. 12th. When the sun dips below the horizon and the sky begins to glow, something special happens at Lost Canyon Ranch Open Space. Twilight on the Trails – Castle Rock Parks and Trails Foundation's signature fundraiser in its 5th year – is a unique gathering that brings the community together in a beautiful, relaxed setting. Enjoy guided sunset hikes, live music, and thoughtfully curated food with a local flair. Whether you come with friends or on your own, it’s a chance to connect with others who share a love for the outdoors. This isn’t a traditional fundraiser. It’s a celebration! In the laid-back spirit of Castle Rock, the theme attire is a “Cocktail on Top; Trail on Bottom” vibe – think blazers with hiking boots. You’ll enjoy great food, drinks, and a lively auction – all supporting the preservation and future of Lost Canyon Ranch Open Space. Space is limited to keep the experience personal, so we encourage early reservations. This year, you can also choose to sponsor a ticket for a community member, helping more people take part in the event and support our trails. Join us: Saturday, Sept 12, 2026 | 5:30 – 9 p.m. | Lost Canyon Ranch Open Space | New price! $75
