Spring is an ideal time for climbing in Portugal, with mild temperatures, fewer rainy days, and beautiful landscapes. This season is typically ideal for various types of climbing, including sport climbing, lead climbing, top rope, bouldering, and trad climbing. Here are the most popular crags: 1. Sintra - Known for its granite boulders and scenic beauty. 2. Arrábida - Limestone cliffs. 3. Cascais - Coastal climbing with a mix of sport and trad routes. 4. Serra da Estrela - Granite climbing in a mountainous setting. 5. Peneda-Gerês - Adventurous multi-pitch routes.
