We report on the attainment of Bose-Einstein condensation of 86Sr. This isotope has a scattering length of about +800a0 and thus suffers from fast three-body losses. To avoid detrimental atom loss, evaporative cooling is performed at low densities around 3\ifmmode×\else\texttimes\fi1012 cm^\ensuremath-3 in a large volume optical dipole trap. We obtain almost pure condensates of 5\ifmmode×\else\texttimes\fi103 atoms.
