There's a concrete boat ramp at the Catamount Rec Area, just like the ones at Pumphouse and Radium, I think it requires that you pay the same fee as at the other two areas, or its included in the fee.
Nothing in the world is more yielding and gentle than water. Yet it has no equal for conquering the resistant and tough. The flexible can overcome the unbending; the soft can overcome the hard. - Lao Tse
