We present new analytic and numerical results for self-gravitating SU(2)-Higgs magnetic monopoles approaching the black hole threshold. Our investigation extends to large Higgs self-coupling, {lambda}, a regime heretofore unexplored. When {lambda} is small, the critical solution where a horizon first appears is extremal Reissner-Nordstr{umlt o}m outside the horizon but has a nonsingular interior. When {lambda} is large, the critical solution is an extremal black hole with non-Abelian hair and a mass less than the extremal Reissner-Nordstr{umlt o}m value. The transition between these two regimes is reminiscent of a first-order phase transition. We analyze in detail the approach to these critical solutions as the Higgs expectation value is varied, and compare this analysis with the numerical results. {copyright} {ital 1999} {ital The American Physical Society}
