CS2 Boulder Callouts: Complete Map Guide

featuring close-quarters combat, narrow choke points, and vertical angles. The map is brand new, and official CS2 Boulder callouts are still being settled by the community. The names below reflect the most commonly used terms so far — expect some variation as the meta develops.

Why Callouts Matter on a New Map

On a new map, shared vocabulary doesn't exist yet. Boulder map callouts are still forming across the CS2 community, which means different players are using different names for the same positions. Getting ahead of that curve now — even with early-stage naming — gives your team a communication advantage before the wider playerbase catches up.

Bombsite A Callouts

A Site — The main bomb site, set in an open courtyard with stone pillars and cover. The central planting area for most T-side executes.

A Long — The long, open pathway leading from T Spawn to the A site. Highly contested and a natural AWP duel zone.

Garden / Courtyard — The outdoor area immediately surrounding A site, featuring stone structures and natural cover.

Monastery — The main religious building adjacent to or overlooking A site. A key CT anchor position.

Balcony — An elevated platform above A site used by CTs to hold against T pushes from A Long or Garden.

Bombsite B Callouts

B Site — The B bomb site, situated inside the monastery buildings with tight corners and close-quarters angles.

B Short — The tighter indoor route leading directly into B site. Faster but more exposed than the Tunnels approach.

Tunnels / Catacombs — Dark underground hallways leading up to the B area. The secondary T-side approach to B.

Pillars — Large stone support structures on and around B site used for post-plant cover.

Heaven — A raised balcony or upper level looking down onto B site. A dominant CT hold during retakes.

Mid Callouts

Mid — The central lane connecting T Spawn to both bomb sites. The primary sniper duel zone and the key to map control.

Connector — A transition hallway or tunnel linking Mid to either the A or B side. Controlling Connector opens both sites.

Arches — Stone archways along the Mid lane used for cover against utility and crossfire setups.

Window — An elevated CT-controlled opening with sightlines straight down Mid. A critical early-round position.

Spawn and Rotation Callouts

CT Spawn — The Counter-Terrorist starting area, positioned to allow rotation to both sites.

T Spawn — The Terrorist starting area, with routes branching toward A Long, Mid, and B Short.

Quick Reference Table

Note: de_boulder positions are based on early community usage. As the map matures in the CS2 map pool, some boulder site names CS2 players use may shift. This guide will be updated as boulder map communication standardises across the competitive scene.
