Pseudo-Tsuga
Massive berms near the bottom, great flow throughout. Less all-out speed than Half Nelson but incredibly fun.
Trail beta
Park at the lower Diamond Head lot (commonly called the 'Pseudo lot') off Garibaldi Park Rd, or stage up at the Climbing Trail lot for Part 1 access. Drive up Mamquam Rd from Hwy 99 (Canadian Tire) which becomes Garibaldi Park Rd. Upper entry is at the SORCA shelter on Ring Creek North FSR. Pseudo drops down-left just before the shelter. Fast, flowy, a couple of optional jumps across Parts 1-3. Lower connector that most riders link after Half Nelson or Angry Midget to get back to the lots.
When to go
Best April through October, SORCA-maintained in Squamish's Ring Creek / Quest University zone. This three-part flow trail system handles moisture reasonably well but is clearly a dry-season trail: the rollable jumps, berms, and bridges ride best June-September. Winter rides are possible on dry-spell days but expect mud on parts 2 and 3.
