Jack and Isaac Bay Preserve

Amazing wilderness area of Saint Croix! Preserved but relatively easy to get to - nice hike to nearly private beaches and amazing snorkeling!

The most beautiful beach I visited on the islands with incredible white sand beaches and snorkeling right off the beach. It's worth the hike

Great views and beaches. Isaac’s Bay beach is partially protected by the reef and a few people were out snorkelling. Not crowded on the day we visited, maybe a dozen other people along the trail in mid-Feb. A small parking lot holds about a dozen vehicles though you can probably park along the shoulder too. There have been some break ins reported so we just left our windows open with nothing of value in the car.

A great place for an intermediate level hike. The path is very rudimentary and rough especially as you start out and then widens a bit. Hiking poles will be helpful. Amazing views from the high points. Very interesting foliage - tropical and desert mixed together! Probably the most pristine beaches in St Croix with smooth, soft sand and beautiful blue water! A relaxing dip in the cool water is the perfect mid-hike break before heading back to reality!

A great hike with a very high beautiful view to effort ratio! Amazing foliage, cacti and more arid plant life. Lots of sea birds. And miles of gorgeous clear water and white sand beaches. A few other hikers on the trail but certainly not crowded.

25May2025: This is a beautiful hike. At the parking lot at the top before you get to Udall point, you can park if there is a spot. Parking lot will hold about eight vehicles. Remember, leave no valuables in sight or even in the car. I recommend you leave the car unlocked with the windows in the back rolled down, as to keep from having a window broken. Some windows had been broken in at the parking lot previously. The hike is not too strenuous. but lose shake in places. You do need to have decent shoes. Unfortunately the sargassa seaweed at Jack's Bay and beach covered everything, and it was unusable. Isaac's Bay is a little better but still not good.

Nice hiking trails, with beautiful beaches and views! I wish we could have snorkled here, but it was too windy/huge waves, tho we still saw a few people out there. Hopefully next time, if we make it back to ST Croix.

Nature at its best. Roads to the beach are well paved, and not like the west side of the island. We were told to not bring anything valuable and roll down the windows of the car in the parking lot so that the windows don’t get smashed out. And we saw the evidence of that in the parking lot. There’s not very many parking spots. Maybe 10 and that’s all the people that seem to be at the beach, which was perfect for us! That being said, the beach and area is gorgeous! Very remote and very few people at the beach, be sure to bring good hiking shoes to make the trek down the path approximately 1 mile to the beach and then there’s miles and miles of beach and mountain side area to hike and explore. Two cool little driftwood huts were constructed to help get out of the sun. The best experience on the whole island.
