This is hands down on the short list of my top 3 favorite boulders on the LRT. Steep, unique, and with a lazy day approach... Alcatraz has several tough boulder problems to choose from, and a couple classics that shouldn't be missed! Be sure to get on "Escape From Alcatraz" for some steep gnar that exits through a hole in the back of the "cave" and "Paladin" for a frustratingly awesome deadpoint up a steep face to a "credit card" thin slot. If your feeling particularly masochistic you can pull onto the "Great Escape" as well... but bring some fresh skin!
