Trail Description
About this trail
From the Perimeter Loop, this trail starts with a short but furious uphill section heading west and a fast, short saddle rising into another short climb. A sustained downhill section follows. The singletrack then enters into a longish climb and passes the entrance to the Proving Grounds Advanced Drop at left. Alpha then becomes a series of descents, rises, and switchbacks among many small ridges, and eventually crosses a long wooden bridge and passes the Landing Zone before heading back north. The return has a challenging uphill section and ends with a wooden berm and wooden bridge features and some last downhill fun--ending at the West Lake Trail just east of the Alpha entrance.

Review: This is another one of my favorite trails... it is close to the LZ/Parking area and is perfect for a quick ride. Challenging enough, and has some sweet features and trail sections. Do not miss out on this gem when getting out to see the rest of the park!

Review: Alpha is a fun trail that close to the LZ so you can get on the trail quickly if you only have a few minutes to ride and it is a blast.

Review: Great Loop with great features that can be passed up if not ready. Includes 3 foot drop, large wooden berm and a big dirt kicker that will sent you flying if you have your wings. Great flow with a few challenging climbs and numerous downhill opportunities.
