The climbing simulator Cairn is expanding its scope with the upcoming release of the On the Trail: Deep Water DLC. Following a period of delay, the developer has confirmed that the expansion is scheduled to launch on Steam on October 29, 2026. This update aims to provide players with fresh environments and mechanical adjustments to the core climbing experience.

New Content and Features

The expansion introduces several additions designed to alter how players approach vertical traversal. Most notably, the DLC adds three distinct climbing locations: Haken, Ruka, and the Lamu climbing gym. These environments are intended to offer varied challenges compared to the base game's existing routes. Furthermore, the update introduces a new playable character named Marco, who brings a unique climbing style to the roster.

Perhaps the most significant addition for those focused on mastery is the new free roam mode. This feature allows players to reload saves and practice specific routes without the pressure of the standard campaign progression. This addition is paired with new water mechanics that provide a safety net for falls, effectively removing the immediate consequences of a slip in specific areas.

Current Promotional Offers

For those who have not yet acquired the base game, there is a temporary discount available. The base game Cairn is currently 20% off on Steam until September 26, 2026. This provides an opportunity for new players to familiarize themselves with the mechanics before the expansion arrives next month.
