At the risk of adding yet another positive review, and causing this place to become even more popular and crowded, here it goes: Mission Cliffs ROCKS! It is the best climbing gym in the city. I love their huge selection of routes, as well as the free classes they offer with the membership. They have so many different options for the routes: they have a wide range of difficulty levels, as well as lengths, and have bouldering options. Also, it's got a great community of people. I've met alot of new friends where who I will climb with when I see them. The sauna is an added bonus, and is great to use after a hard workout.
