We study the fractal geometry of O(n) loop configurations in two dimensions by means of scaling and a Monte Carlo method, and compare the results with predictions based on the Coulomb gas technique. The Monte Carlo algorithm is applicable to models with noninteger n and uses local updates. Although these updates typically lead to nonlocal modifications of loop connectivities, the number of operations required per update is only of order 1. The Monte Carlo algorithm is applied to the honeycomb O(n) model for several values of n, including noninteger ones. We thus determine scaling exponents that describe the fractal nature of O(n) loops at criticality. The results of the numerical analysis agree with the theoretical predictions.
