2.Private Algarve: Benagil Caves, Lagos Cliffs & Hidden Beaches

★★★★★★★★★★5.0 · 134 reviews · 12 to 14 hours (approx.) · from $544

Spend 12 to 14 hours exploring the Algarve from Lisbon with David, Daniel, or another professional guide. Visit Algar Seco, Benagil Cave, Praia da Marinha, Ponta da Piedade, Praia do Camilo, and Praia dos Estudantes. Hotel pickup, bottled water, and private transport are included. The Benagil boat ride costs extra.

“We enjoyed the gorgeous locations the guide took us, and the additional boat ride to the caves is a must-do to see many unique vantage points. We appreciated his helpful tips, kindness and generosity (bought us snacks, offered wi-fi, charging cables), including taking us to a restaurant that he and other locals frequent. He was even gracious to cover our payments for reimbursement afterward. It was almost like being toured by a friend. However, it would've been five-stars perfect if opinions on politics, religion, race, and gender issues were kept to a minimum, or better yet, none. We travel for respite, after all. We're thankful that our guide drove safely…”
