The Park Service has permanently closed the trail connecting San Pedrillo and Sirena ranger stations. This trail is a 25.5 km trajectory that is a technical hike and too rigorous for most hikers to safely transit. This is not the distance that must be covered but also because there are three rivers that must be crossed, which due to their locations cannot all be crossed at low tide. Much of the hike is under the open sun, and to avoid this, the trail must be reasonably hiked in part at night. On top of complications of physical exertion and the technical aspects of the hike, there is no support along the way, most notably no water supply, so hikers are additionally burdened by having to carry even more water. In light of the many safety concerns that the trail poses, this trail is no longer open to the public.
For multiple day park expeditions originating in Drake, it is certainly possible to hike from Drake to San Pedrillo, but a boat charter is required
The trail between San Pedrillo and Sirena has been closed to the public for two years and is no longer an option for visitors. Multiple day excursions from Drake must therefore include private boat transfer between San Pedrillo and Sirena.
At the moment it is uncertain whether this trail will be re-opened to the public or whether it will be opened conditionally to certain groups or to guided groups. However, since this trail traverses the tallest part of the forest with the largest trees and most dense concentration of wildlife, it is hard to imagine that it will be permanently closed. For now, however, the Park Service is publicly stating that the trail is not likely to be re-opened for the coming dry season.
