The only way onto the islands are via boat. Private boats can be chartered for around $100 per day. Otherwise collective boats leave from a pier in San Carlos near the current construction along the seawall. The schedule is San Carlos to Solentiname Tuesday and Friday 1pm for C$80 and returning the same days at 4:30am for the same price. You might be lucky and find someone from the island running around in Sna Carlos and giving you a ride to the islands.
