Alpine Mountain Coasters & Slides

Make the Most of Your Mountain

At ADG we understand the investment you are making when you decide to purchase and build an alpine coaster, slide or waterpark attraction. No other company offers the in-depth analysis that ADG provides.  We approach your purchase with a project mindset and start by scheduling an on-site Mountainside® Intake Assessment designed to analyze everything from soil conditions to existing infrastructure and resort operations, to construction needs, timelines and budget constraints.  This allows you to formulate an accurate up front idea of what building your attraction will truly cost.
